Caltrain Sound Mod: Enhancements and Adjustments - Peninsula Corridor

v1.4 - Released 06/19/26 - See List Below for list of changes made:
-Fixed sound mixing for the passenger ambience in the coach vestibule (Gallery Coaches) and cab vestibule (Gallery and Bombardier Coaches)
-Added and adjusted several rattling sounds, and added cab squeaking sounds for both the F40PH-2CAT and MP36PH-3C locomotives
-Re-implemented and adjusted cab wind sounds to both the Gallery and Bombardier Coach cab windows, as they were not implemented correctly in v1.3.
Going forward, to maintain consistancy between the MP36PH-3C and Bombardier coaches in both this sound mod, and my Metrolink Sound Mod, any sound adjustments done on both pieces of rollingstock in the Metrolink Sound mod will also be applied to this mod as well.
(For a full rundown of the sound changes done on the included locomotives in this mod, please view the dropdown menus of each of the rollingstock below).

v1.3 - Released 06/05/26 - See List Below for list of changes made:
-Implemented Rail Singing from NYS onto route. (also implemented in my Caltrain Logo Restoration + Small Route Enhancements & Adjustments mod)
-Adjusted several sound attenuations to each locomotive.
-Adjusted several occlusion mixes to prevent external sound bleeding into the cab of each respective locomotive.
-Added cab wind sounds to both the Gallery and Bombardier Coaches.
(For a full rundown of the sound changes done on the included locomotives in this mod, please view the dropdown menus of each of the rollingstock below).

v1.2 - Released 04/17/26 - See List Below for list of changes made:
-Spliced Radio Chatter samples to remedy, though not fix entirely, an issue where the original thirty-minute sound sample loops would restart when switching between camera views. There is still an issue where some of the individual radio transmissions may repeat however.
-Implemented new and missing sounds that were not included in v1.1 of this mod. The bulk of these changes are mostly present in the Bombardier and Gallery Coaches, as well as the UP GP38-2 locomotive.
-Reverted several sounds that were converted to stereo in v1.1 back to mono. This was mainly due to some of the sounds either being too loud or being mixed weirdly with the sound formats and cue changes.
-Increased Max Channels Count from 256 sounds to 1024 sounds on ALL locomotives associated with Peninsula Corridor. This is mostly a band-aid fix to ensure that there are no sound anomalies that occur when using this mod, although this will not prevent them entirely. Some examples of these sound anomalies range from rapid fire sounds, sounds cutting in and out, or sounds disappearing entirely (this issue is especially prevalent on the MP36PH-3C, however it does apply to the rest of the rolling stock to various degrees).
As of this recent update, I am mostly satisfied with the changes made to this mod. Any new updates done with this mod will be smaller fixes and updates that may or may not have been adressed with either this version, or the previous version.
(For a full rundown of the sound changes done on the included locomotives in this mod, please view the dropdown menus of each of the rollingstock below).

v1.1 - Released 12/25/25 (First Release) - See List Below for list of changes made:
-Changes several sounds of all of the Peninsula Corridor rollingstock (including the MP36PH-3C, Bombardier Coaches, and MP15DC DLC).
(For a full rundown of the sound changes done on the included locomotives in this mod, please view the dropdown menus of each of the rollingstock below).

Radio Chatter:
-Adds radio chatter for ALL locomotives associated with the Peninsula Corridor DLC, which also includes the MP36PH-3C, Bombardier Cab Car, and MP15DC (Recordings taken from RailroadRadio.Net). v1.2 - These samples are spliced into 5 different categories:
1. Signal Callouts - Should be Self Explanatory
2. Station Callouts - Again...Should be Self Explanatory
3. Miscellaneous Transmissions - Smaller or otherwise unintelligible radio transmissions
4. Conversations - Larger radio transmissions usually consisting of a couple random scenarios such as a train going into PTC emergency, or engineers acknowledging and complying with a stop and protect rule at a grade crossing (GCOR 6.32.2 - Procedure 2).
5. Static One-shots - Smaller radio transmissions which consist of short radio static noises.
These transmission splices will usually be randomly selected, followed by roughly 30 seconds of dead air after the initial transmission.

Rail Singing
-Implements Rail Singing feature onto route (Ported from NEC: Stamford). These sounds function exactly the same as they do on NYS, in which noise from the rails ("Rail Singing") will play as the train approaches, as well as the sounds getting louder when the train reaches a faster speed when viewing the train in free camera view.
NOTE: These sounds have also been implemented in my Caltrain Logo Restoration + Small Route Enhancements & Adjustments Mod, you do not need both mods for it to work.

Known Issues:
-Due to my personal limitations of how the editor works, the radio chatter cannot be turned off. The on/off toggle for the radio chatter will be something that I will try to figure out how to get working in the future.
-Due to the way that the radio chatter is setup, there is a possibility that you may end up hearing some repeat individual transmissions.
-As these recordings were recorded in October of 2025, nearly a year after the full electrification of the IRL Peninsula Corridor line took place, there are instances where you will hear the electronic bell sounds of the Stadler KISS EMU's in the recordings; keep in mind the Peninsula Corridor DLC in TSW takes place before the Caltrain Electrification. If you are a foamer, and somehow present-day recordings with modern-day sounding electric rollingstock in the background hurts your timeframe-realism OCD when playing a 2016-2019 era route populated with only diesel locomotives, it's probably advised to not use this mod. :)

-Added new exterior and interior horn sounds (Sounds courtesy of SCAX868 of TheAudioShack)
-Added Air Hiss sounds to the interior horn that play concurrently when sounding the horn from inside the cab car (Sounds recorded by me) v1.2 - Removed Air Hiss sounds completely, as a new horn has been implemented in which the hissing noises are present in the new sound samples.
-Removed interior air discharge noise when sounding the horn; The new horn sound samples contain it's own air discharge noises.
-Fixed an issue where the Attendant Call Bell would stop for a split second after initially pressing the button; this was fixed simply by extending the length of the sound sample as the sample originally was far too short.
-Added improved interior wind sounds when opening the windows, as well as the center door vestibule, in the cab car (Ported over from BOW B/CTC-5 coaches) v1.3 - Reinstated the open window wind roar sounds and adjusted the sound cues so that the wind roar sounds are slightly quieter. Re-implemented new sounds into separate cues so they are similar to how they are set up in the BOW CTC-5 cab car. v1.4 Re-implemented and adjusted cab wind sounds to both the Gallery Coach cab windows, as they were not implemented correctly in v1.3.

-v1.2 - Added Interior Doorway HVAC sounds that were previously unused in the Gallery Coaches files.
-v1.2 - Re-attenuated Air Sander, Bell Air & Stop, and Wiper Air start & loop cues so the sounds do not cut out when leaving the cab passenger seat.
-v1.2 - Added new exterior bell sounds (Sounds courtesy of SCAX868 of TheAudioShack) v1.3 - Removed bell sounds from v1.2 and implemented both new interior and exterior bell sounds (Sounds courtesy of SCAX868 of TheAudioShack).
-v1.2 - Re-Isolated interior bell sound samples to remove the internal HVAC noises that were initially found in the sound sample.
-v1.2 - Added new bell stop sound (Sounds courtesy of SCAX868 of TheAudioShack)
-v1.2 - Linked interior running and rumbling sounds to the root socket in the mesh, as this allowed for the sounds to be mixed 1-to-1 with the rolling stock the sounds were ported from (in this case the sounds were from the BOW B/CTC-5 Coaches)

-v1.2 - Added phone pick-up/hang-up noises to the contact signaler phone (Ported over from NYT Amfleet Cab Car).
-v1.2 - Adjusted the Cab Door rattling cues so that the rattling sounds are much faster in speed, and the pitch and volume of the sounds increases as the train moves to a faster speed.
-v1.2 - Removed horn originally implemented in v1.1, and added new exterior and interior horn samples (Sounds courtesy of SCAX868 of TheAudioShack)
-v1.2 - Re-attenuated Ditch Relay cues so the sounds do not cut out when leaving the cab passenger seat.
-v1.2 - Adjusted the interior Door Vestibule whistling cues so that the pitch of the sound increases as the train moves to a faster speed.
-v1.2 - Implemented Passenger Ambience. v1.4 - Fixed sound mixing for the passenger ambience in the center vestibule and cab vestibule
-v1.3 - Removed Default exterior running sounds and implemented new running sounds (Ported from BPE/NYT/NYS Amfleet Coaches, the cues however use the default running bass alongside the ported over sounds).

Default sounds converted from mono single channel to stereo dual channel format:
-Exterior HVAC (Originally Unused)
-Interior HVAC
-Bell Air Loop and Park v1.2 - Reverted bell air loop back to original mono sound and removed default bell park sound

-Interior Bell
-Exterior Bell Actuator v1.2 - Removed bell actuator sound
-Exterior Running v1.2 - Reverted back to original mono sound
-Exterior Joints v1.2 - Reverted back to original mono sound

Known Issues:
-Originally planned to include interior HVAC for the center doorway vestibule. This was removed due to the internal sounds being heard on other formations on the route. Not sure if this is an attenuation-related issue, or if the occlusion files might be broken. v1.2 - Implemented interior HVAC sounds to the center doorway vestibule.
-For some reason, when traversing coaches starting from the cab car, the Interior HVAC noises become much louder than what they normally are. v1.2 - Linked interior HVAC sounds to the root socket in the mesh as this fixes the interior HVAC loudness issue.
-When travelling on certain portions of the route, the joint sounds (both Exterior & Interior) will begin to play over each other. This is due to the track condition on certain points of the route being set to rough, which causes the joint sounds to play continuously, despite there being no junctions present at all on the sections of the route where it does happen (This issue also pertains to the Bombardier Bi-level coaches as well)
-v1.2 - When switching between camera views with the bell activated, the interior bell sound may become out of sync with the exterior bell sound. This is due to the bell cue being setup differently than how it is normally supposed to be setup.
-v1.2 - Passenger Ambience has mixing issues where it is equally as loud in the cab vestibule of the Gallery Cab Car as it is in the passenger seating area. Not sure if this is something that can be fixed, as this issue is not present in any TSW6 rollingstock that has Passenger Ambience implemented. This also applies to the Bombardier Bi-Level Coaches as well. v1.4 - Passenger Ambience mixing fixed
-v1.3 - For some strange reason, the interior rattle, cab wind, and cab wind whistle sounds sometimes cut out when switching to one of the external cameras, then back to the cab camera. Not sure entirely if this is a sound priority issue of if this is due to the numerous amount of new looping sounds implemented in the cab vestibule of the Gallery Cab Car, but for the time being, it cannot be fixed.

New and Adjusted Sounds:
-Updated Horn and Cab Control Attenuations (Ported over from SMH SD40-2)
-Swapped default horn button sound to a different push button sound located in the GP38-2. v1.2 - Implemented horn button sound from CJP ES44C4.
-Added Interior Reverser Motor sounds (Ported from Griggs CSX GP38-2 sound mod)
-New Exterior and Interior horn (Ported over from SMH SD40-2). Only the horn start and loop works currently as I was unable to get the horn end sound to work, despite my best ability to do so, though I do intend on getting it working next time I update this mod. v1.2 - Implemented the horn end sound for the three part horn. (A HUGE thanks to SpaceyKat for helping implement the logic in the locomotive's RVV for the three part horn sound to work correctly)
-v1.2 - Updated Exterior Engine Sound Attenuations.(Ported over from SMH SD40-2)
-v1.2 - Added phone pick-up/hang-up noises to the contact signaler phone (Ported over from NYT Amfleet Cab Car).
-v1.2 - Slightly adjusted the volume in the cab Visors
-v1.2 - Slightly increased the volume for the Automatic Brake Lever, and Throttle Lever
-v1.2 - Added new Dynamic Brake Sounds (Ported from Griggs CSX GP38-2 sound mod). Adjusted the attenuation so the Dynamic Brake Sounds are equally as loud as the engine when viewing the locomotive from a distance.
-v1.2 - Added new Intertial Filter Blower sounds (Ported from Griggs CSX GP38-2 sound mod). Adjusted the cue so it is similar to the SMH SD40-2
-v1.2 - Added new Radiator Fan Sounds (Ported from Griggs CSX GP38-2 sound mod). Adjusted the cue so it is similar to the SMH SD40-2
-v1.2 - Added new Engine sounds (Ported from Griggs CSX GP38-2 sound mod). Adjusted the cue so it is similar to the SMH SD40-2.
-v1.2 - Updated Interior occlusion mixes (Ported over from SMH SD40-2)

Default sounds converted from mono single channel to stereo dual channel format:
-Exterior Enginesounds v1.2 - Removed default sound entirely and implemented new sounds.

Known Issues:
-Interior Radio Chatter sounds can heard when playing a different locomotive. Not sure if this is an attenuation related issue or not. v1.2 - Radio Chatter issue fixed
-Dynamic Brake Fan sounds have a weird clipping issue once the loop replays. Not sure if this is an issue with the re-built cue, or something with the RVV.

Note that all changes implemented here have also been implemented for the MP36PH-3C in my Metrolink Sound Mod for consistency between the two locomotives.
New and Adjusted Sounds:
-Added new exterior and interior horn sounds (Sounds courtesy of SCAX868 of TheAudioShack)
-Added horn valve solenoid pop to the horn sound (Exterior horn sound courtesy of CorniestCob's Caltrain MP36PH-3C Horn Mod, and Interior horn sound courtesy of SCAX868 of TheAudioShack) v1.3 - Adjusted the horn sound cues to correct when the horn valve solenoid pop sounds play.
-v1.2 - Added horn lever up and down sounds to the horn lever (Ported from BOW/BPE HSP46) v1.3 - Removed horn lever up and down sounds from BOW/BPE HSP46 and implemented new horn lever sounds (Ported over from GWR Class 166)
-v1.2 - Silenced Emergency Valve air cue when activating the secondman Emergency Brake
-v1.2 - Added phone pick-up/hang-up noises to the contact signaler phone, as well as rattling noises when operating the train at speed (Ported over from AVL/SBD F125). v1.4 - Swapped contact signaler rattling cue with different cue.
-v1.4 - Added cab squeaking sounds when operating the train at speed (Ported over from AVL/SBD F125).
List of assets and sounds ported over from the Metrolink MP36PH-3C over to the Caltrain MP36PH-3C:
For the Caltrain MP36PH-3C, I did my best to try and make the sounds as 1-to-1 as possible with the Metrolink MP36PH-3C which mainly involved re-creating the exact same sound cues as the Metrolink variant, as well as linking them similarly to how the Metrolink MP36PH-3C's sound are in it's respective RVA (the Caltrain MP36PH-3C does not have an RVA so it's sounds are linked to the RVV).
-Attenuations - Bell, Exterior Cab Door, Interior Cab, Wipers (Both Exterior and Interior), Compressor (Both Exterior and Interior), Engine, and HEP (both Exterior and Interior).
-All Occlusion Mixes
-All Audio Curves
-Exterior and Interior Compressor Sounds
-Bell Sound (the bell ported from the Metrolink MP36PH-3C has also been converted to Stereo, as the sound sample was originally Mono)
-Sander (just the start and looping noises, as I was not able to get the sander end sounds to work)
-Wipers (Only the Exterior and Interior wiper impact noises, as I was not able to get the Interior Wiper Hiss loop sounds to play)
-Bell Button
-Reverser, Throttle, and Independent Brake Handles (I did not bother changing the Automatic Brake handle sounds as I personally like the sounds from the Caltrain version better, although the sound parameters have been adjusted to match the Metrolink version)
-Exterior and Interior Dynamic Brake Air Hiss
-Exterior and Interior Cab Door. v1.2 - Implemented missing interior door sounds for when the door opens fully on the interior of the locomotive.
-Interior Windows
-Exterior and Interior engine sounds v1.4 - Adjusted the enginesound cue so the enginesound is slightly louder both externally and internally.
-Exterior and Interior HEP sounds. v1.3 - Adjusted the HEP cue so that only the exterior HEP sounds play instead of the interior ones. This was mainly done to "correct" an issue where the interior HEP sounds would play in the first coach behind the locomotive. This is mainly due to the socket placement of where the HEP sounds are linked and cannot be fixed. The cue is mostly set up like this on the SBD MP36PH-3C as well.
-v1.2 - Emergency Brake Lever
-v1.2 - Brake Cut-Out Valve
-v1.2 - Fuse Cabinet
-v1.2 - Sun Visors

Default sounds converted from mono single channel to stereo dual channel format:
-Interior Joints v1.2 - Reverted back to original mono sound
-Bell

Known Issues:
-No Engine High Idle sound plays, both when inserting the Reverser, and when the compressor turns on. This is likely a simugraph-related issue, in which it cannot be edited.
-Interior HEP noises overlap when switching the HEP Isolate/Run switch, due to there being no low idle noises on the Metrolink MP36PH-3C. This is something that I do potentially plan on fixing overtime, as it is technically possible to creating low idle HEP sounds specifically using pitch-editing tools found in the editor, however I am going to leave them here as is. v1.2 - Implemented the low and high idle noises on the Caltrain MP36PH-3C using the samples from the Metrolink MP36PH-3C. This method is not perfect however as some of the sounds do still overlap between when some of the sounds fade in or out.
-HEP noises may stop playing after a certain period of time. Not sure why this happens, though simply turn the HEP Isolate/Run switch for the sounds to play again.
-Small attenuation issue where the interior HEP, joint, and engine sounds can be heard in the first car behind the engine. v1.3 - Interior HEP sounds "disabled" but not removed from the HEP sound cue to correct this attenuation issue.
-No interior air brake sounds due to missing audio sockets in the mesh.
-No interior wiper hissing noises due to missing audio sockets in the mesh.
-No sand end noise when releasing the sander button due to missing parameters in the RVV.
-For some strange reason, when playing the locomotive for a certain length of time, nearly all of the sounds will start glitching out. I have updated the stereo max count to allow 256 sounds - v1.2 - now 1024 sounds - as it basically, though not entirely, remedies this sound bug. I am not sure exactly why this happens specifically with the locomotive, however it seems it cannot be fixed due to the age of the DLC.

Note that all changes implemented here have also been implemented for the Bombardier coaches in my Caltrain Sound Mod for consistency between the two coaches.
New and Adjusted Sounds:
-Updated Bell, Cab, Door Audio, Horn (Both Interior and Exterior), Running, and Interior Wind attenuations (Ported over from both AVL/SBD Rotem Coaches & AVL/SBD Bombardier Coaches)
-Updated Interior occlusion mixes (Ported over from AVL/SBD Rotem Coaches).
-Swapped Brake Cut-out valve sounds with different valve open/close sounds found in the Bombardier Coaches.
-Added Improved Reverser Handle Sounds
-Added improved Wind sounds when opening the windows, as well as the center door vestibule in the cab car (Ported over from AVL/SBD Rotem Coaches). v1.3 - Reinstated the open window wind roar sounds and adjusted the sound cues so that the wind roar sounds are slightly quieter. Re-implemented new sounds into separate cues so they are similar to how they are set up in the AVL/SBD Rotem cab car. v1.4 - Re-implemented and adjusted cab wind sounds to both the Bombardier Coach cab windows, as they were not implemented correctly in v1.3.
-Adjusted the sound parameters of the Throttle/Dynamic brake and Automatic Brake Handles to play sounds when the handles are in certain positions (this was done as I had originally planned to implement the Throttle/Dynamic Brake handle sounds from the SBD F59PHR, and the Automatic Brake Handle sounds from the BOW F40PH-3C, but couldn't due to the limitations of my editor allowing me to create the cues) v1.2 - Removed default Throttle/Dynamic Brake and Automatic Brake handle sounds
-Added phone pick-up/hang-up noises to the contact signaler phone, as well as rattling noises when operating the train at speed (Ported over from AVL/SBD Rotem Coaches).
-Adjusted volume and re-adjusted sound class for the Cab Door on the Bombardier Cab Car. Also included closing sounds for when the cab door closes in both the cab vestibule, and the passenger vestibule.
-Adjusted volume and re-adjusted sound class for the end vestibule doors.
-Added new and improved passenger door opening and closing sounds (The door opening and closing sounds were ported over from the SBD Bombardier Coaches with the alarm sounds removed from the samples, while the "Caution, the doors are about to close" announcement sounds was taken from this video with permission from YouTuber "Raised Letter" to use for this mod: https://www.youtube.com/watch?v=5\_O6eMIr0c8\&lc=UgxNap7V9ewpXebruXB4AaABAg.AP\_Ypz5Yk\_AAP\_ZLkIA-gg)
-Added Improved Exterior & Interior Running, and Joint sounds (Ported over from AVL/SBD Rotem Coaches)
-Added New exterior and Interior horn sounds (Sounds courtesy of SCAX868 of TheAudioShack). v1.2 - Added secondary Exterior and Interior horn sounds. These sounds are recordings of one of the two Bombardier Cab Cars that have a Nathan Airchime K2 horn, and are setup to switch between either the P2 or the K2 horn when spawning the coaches into a route (though for some reason, the cue does not work properly to do so, only the K2 horn will be selected) (Sounds courtesy of SCAX868 of TheAudioShack)
-Improved doppler effect of the exterior bell
-Added exterior bell actuator sounds (Ported from SFJ F40PH-2CAT)
-Added Air Hiss sounds to the interior horn that play concurrently when sounding the horn from inside the cab car (Sounds recorded by me)
-v1.2 - Removed sander sounds when activating the sander button (In real life, pressing the sander button on the Bombardier Cab car would activate the locomotives sander as there is no sander on the cab cars themselves)
-v1.2 - Removed parking brake apply and release sound cues when activating the parking brake button.
-v1.2 - Added sounds to the guard panel buttons (For some reason there are a few buttons in which the sounds will not play. Not sure entirely why this happens, likely to do with the way the inputs are setup in the RVM as well as the default cues).
-v1.2 - Re-Attenuated Wiper Air cues so the sounds do not cut out when leaving the cab passenger seat.
-v1.2 - Added new horn plunger button sounds (Ported from BOW B/CTC-5 Coaches)
-v1.2 - Re-Attenuated Cab Window cues so the sounds do not cut out when leaving the cab passenger seat.
-v1.2 - Added new visor sounds (Ported from SFJ MP36PH-3C)
-v1.2 - Added new interior Wiper Blade sounds (Ported from AVL/SBD Rotem Coaches)
-v1.2 - Added new Automatic Brake Handle sounds (Ported from BOW F40PH-3C)
-v1.2 - Added new Throttle/Dynamic Brake Handle Sounds (Ported from SBD F59PHR)
-v1.2 - Added new Driver Door Blind sounds (Ported from AVL/SBD Rotem Coaches)
-v1.2 - Adjusted the sound parameters when activating the Wiper Switches
-v1.2 - Added sounds to the end door of the end vestibule in the cab car.
-v1.2 - Added sounds to the gangway barrier of the end vestibule in the in the cab car.
-v1.2 - Linked interior running sounds to the root socket in the mesh, as this allowed for the sounds to be mixed 1-to-1 with the rolling stock the sounds were ported from (in this case the sounds were from the AVL/SBD Rotem Coaches)
-v1.2 - Added and mixed External HVAC sounds to blend into the internal HVAC cues
-v1.2 - Implemented Passenger Ambience

Default sounds converted from mono single channel to stereo dual channel format:
-Sander v1.2 - Removed default air sander sound
-Air Discharge v1.2 - Reverted back to original mono sound
-External Bell
-External HVAC v1.2 - Reverted back to original mono sound
-Internal HVAC

Known Issues:
-HVAC noises may stop playing after a certain period of time. Not sure why this happens, though simply turn the HEP Isolate/Run switch in the MP36PH-3C for the sounds to play again.
-Small clipping sound with interior bell loop, though this clipping sound isn't really noticeable when running the cab car at higher speeds.
-When travelling on certain portions of the route, the joint sounds (both External & Internal) will begin to play over each other. This is due to the track condition on certain points of the route being set to rough, which causes the joint sounds to play, despite there being no junctions present at all on the sections of the route where it does happen (This issue also pertains to the Gallery coaches as well)
-v1.2 - As mentioned above, I have added a secondary horn that will be selected at random when spawning the Bombardier Coaches onto a route. However for some reason, the cue does not work properly to do so, as only the K2 horn will be selected when spawning in the coaches. This will be something that I look into fixing in a possible hotfix.
-v1.2 - Passenger Ambience has mixing issues where it is equally as loud in the cab vestibule of the Bombardier Cab Car as it is in the passenger seating area. Not sure if this is something that can be fixed, as this issue is not present in any TSW6 rollingstock that has Passenger Ambience implemented. This also applies to the Nippon Sharyo Gallery Coaches as well. v1.4 - Passenger Ambience mixing fixed

New and Adjusted Sounds:
-Updated Bell and Horn attenuations (Ported over from BOW F40PH-3C) v1.2 - Removed Horn attenuations as the way the exterior horn is mixed in it's respective sound cue caused the horn to be heard from a very far distance.
-Added new bell plunger button sounds (Ported from SFJ Gallery Cab Car)
-Added new horn plunger button sounds (Ported from SFJ Gallery Cab Car)
-Added Interior Reverser Motor sounds (Ported from Griggs CSX GP38-2 sound mod)
-Added new exterior bell sounds (Ported from SFJ F40PH-2CAT) v1.3 - Removed bell sounds from v1.1 and implemented new bell sounds (Ported over from NECNY SW1000R).
-Added new interior horn sound (Ported from the AEM-7 found in the Northeast Corridor DLC in Train Sim Classic). v1.2 - Redid hornsound cue to better mix the interior horn.
-Added Air Hiss sounds to the interior horn that play concurrently when sounding the horn from inside the cab of the locomotive (Sounds recorded by me)
-Remixed exterior horn sound samples to include re-verb. v1.2 - Redid hornsound cue to better mix the exterior horn.
-Added attenuations to the interior rattling and movement sound cues to fix an issue where the sound would be heard when passing by the MP15DC while playing in the cab of another locomotive.
-v1.2 - Fixed an issue with the air brake sound cues in which applying either the Automatic Brake or Independent Brake would cause the brake sounds to rapidly play.
-v1.2 - Added phone pick-up/hang-up noises to the contact signaler phone (Ported over from NYT Amfleet Cab Car).
-v1.2 - Added doppler effect to the engine sound cues.

Default sounds converted from mono single channel to stereo dual channel format:
-Exterior Enginesounds v1.2 - Reverted back to original mono sound
-Exterior Horn Sound

Known Issues:
-No doppler effect on the Exterior Engine sounds, since for some odd reason, editing the engine sound cues causes the engine sound to not play whatsoever. Not sure why this happens exactly. v1.2 - Doppler effect added on engine sound cues
-Window rattling sounds can be heard from the inside of other locomotives when passing by the MP15. For some reason I must've never gotten around to fixing the issue, though I will be sure to fix this hopefully in another update. v1.2 - Fixed internal attenuation issue with the window rattling sounds
