This mod provides a necessary and essential fix to Boston Sprinter, being able to use the Boston Worcester HSP46s and Rotem Cars on the route that contains the MBTA Boston - Providence/Stoughton Line.
Initially, the HSP46s and Rotem Cars were supposed to have subbed into the route (as evidenced by looking through the formation properties in the editor) when the MBTA Commuter DLC was released as Boston Sprinter has had subbing enabled since release. However, due to the way that the game allows substitution from other DLC, the HSP46s and Rotem Cars never appeared in Boston Sprinter, and will never likley be fixed (given that DTG has given up attempting to fix the substitution for the MP36 and Bombardier Cars on Antelope Valley Line).
Without the use of this mod, the only rolling stock from the MBTA Commuter DLC to be playable on Boston Sprinter is the updated F40PH-3C and B/CTC-3 cars.
Note: Due to the fact that the MBTA services on Boston Sprinter uses only 1 formation for ALL of the services instead of the occasional fixed formations used on many of the services in the Boston - Worcester route, there may be repeated looking formations on several of the MBTA services throughout the route.
v1.3 Update: Updated Scenario and Training Modules: As of the most recent version of the mod, I have updated all of the scenarios and training modules on Boston Sprinter to include the BOW rollingstock on the MBTA formations, including the HSP46's and Rotem Bi-Levels:
-The scenarios "Marching In, Reverse Engineering, Gimme 5, High Speed US, and I Just Cleaned There" uses a mix of the BOW Single Level and Bi-Level coaches on all MBTA Formations, with either an HSP46 or an F40PH-3 as the main locomotive. The latter three scenarios are only playable with the Amtrak Acela DLC installed.
-The MBTA scenarios "Foundations, Cold as Ice, and Long Way Round" use the BOW F40PH-3 and CTC-3 as the main playable locomotives instead of the BPE versions and uses a mix of the Single Level and Bi-Level coaches on their respective formations; they do not use the HSP46 and CTC-5 as the main playable locomotives due to incompatibility issues with the objectives needed to progress through the scenarios. The rest of the MBTA formations found in these scenarios use a mix of the BOW Single Level and Bi-Level coaches, with either an HSP46 or an F40PH-3 as the main locomotive.
-Due to one of the training modules using a MBTA formation found in one of the scenarios, all of the training modules on Boston Sprinter have been updated as well to include the BOW rollingstock on the MBTA formations. The F40PH-3C training module is sadly broken as it will not let you progress after the objective "Hold the Start Switch for 4 seconds" (this is due to the fact that the tutorial is scripted specifically for the BPE F40PH-3C in mind). All other training modules work as intended (including the CTC-3 training module, which uses the BOW CTC-3 instead of the BPE CTC-3), and use a mix of the BOW Single Level and Bi-Level coaches, with either an HSP46 or an F40PH-3 as the main locomotive for all of the MBTA Formations on all of the training modules.
Version and Release History

-Removed BPE F40PH-3 and CTC-3 from timetable formations
-Updated all MBTA formations on the scenarios to include only the BOW rollingstock.
-Updated all MBTA formations on the training modules to include only the BOW rollingstock.
v.1.2 - Released 4/11/25:
-Re-created the formations in the FRM_MBTA files, rather than creating the formations in the the NEC_Formation files.
-Removed BPE coaches from the formations due to issues with the doors not opening when loading/unloading passengers (the BPE CTC-3 cab cars however will remain playable with this mod for consistancy reasons with BOW which keeps the BPE CTC-3 playable, albiet on a few services for that route removed BPE verisons as of v1.3).
-Re-adjusted the substitution probability to accomodate said removal of BPE coaches from formations.
v1.1 - Released 3/25/25:
-Adjusted the substitution probability on the MBTA formations to generate somewhat more "realistic" formations that were present in 2019 (the timeframe in which the timetable was set in).

In response to Dinosbacsi since I cannot post pictures on replies...
Interesting, I have seen that a few times with a similar mod that I had installed from discord, though coincidentally enough, that only seemed to happen with the Boston Sprinter rolling stock. I ran through a service with this mod installed and so far no issues with the doors, although occasionally the trap doors would open on the higher level portion of the low level platforms, and even then that only happened once (see image below)
THANK. YOU
omg i thought this would never happen!
Did another run and yeah, there is something wrong when the two versions of coaches mix in a consist. Here is an example of the two single level cars. You can see which is which by the new one having a detailed guard panel and the old one does not. The original Boston Sprinter variants open their doors, while the newer ones do not.
This only happens when they mix. If it's only Boston Sprinter cars or only MBTA Commuter cars, then it's fine.
After some invastigation I have noticed that the MU and communication cables between the two variants of cars are broken.
Here are the cables between two old Bostron Sprinter cars.
And here are the cables between an old Boston Sprinter and a new MBTA Commuter car. The MU cable is there, but twisted and goes through the couplers, while the comms cable is completely missing (I checked both sides)
So I guess it must be something related to this.
After playing several services on BPE with my mod, I can safely say that, apart from maybe the first coach located behind the locomotive, I have not had this issue occur on this route but only a few times at a couple stations, mainly between canton junction and Providence (and even when the issue did arise, it involved the entire formation including the outdated BPE coaches). Unfortunately, since I have not had this issue occur on my end with my mod installed, I wouldn't really be able to fix the issue on your end.
Ah, don't get me wrong, I didn't expect you to fix it. I assumed it is simply an issue with the base rolling stock itself.
I wonder what might cause it to happen for me but not for you. Do you have other mods affecting the MBTA stock that might somehow cause it to work properly on your end? lol
Update: After playing through a few timetable sessions, I have indeed noticed that there is, in fact, an issue on my end where the BOW stock doors won't open when loading and unloading passengers, and only the BPE specific rolling stock will open their doors when loading/unloading passengers. This issue seems to only happen at specific stations such as the Providence and Stoughton stations, as well as playing the BPE CTC-3 cab car.
I'll be issuing an updated version of the mod in the next day or so that will remove the BPE coaches from the formations to prevent this from happening, although the BPE cab car will still remain playable.
Looking at the comments the Dinosbacsi posted, I'm having the same issue where some of the railcars dont have their doors opening. It seems like the rolling stock is mixed with Worchester, and Boston Sprinter rolling stock, causing the doors to not open. I dont think the two versions are compatible.

Modders once again doing what DTG can't be bothered to fix. Amazing, my man.
However I did notice that the doors on the MBTA Commuter stock don't open at stations. Only the original Boston Sprinter variants open their doors. Some compatibility issue I assume(?).
Regarding this one, I had another run where I got a full bi-levels consists. The doors worked fine this time around. Might be something to do with the old and new stock mixing?
