AP Sky Accurate Time of Day

Description

Program Synopsis
The 2D skies in Train Simulator Classic are only accurate for four days a year (one in each season) and for one location in the UK. This program allows them to be accurate for every day of the year, no matter where the route/scenario is in the world. You can drive with the correct sun/moon trajectories, sun/moon rise/set times, lighting, sky colours and adhesion based on the scenario date and location, whilst using the skies from the Armstrong Powerhouse Sky & Weather Enhancement Pack 2.0. Due to its complex nature, it is essential that you read the manual before attempting to use this program.

Please note that because Quick Drive scenarios do not show up in the scenario list like Career, Standard and Free Roam scenarios do, they are NOT SUPPORTED by this program. They are made by the simulator when you click to load into them, so it's not possible to select them beforehand.

Detailed Description
Train Simulator Classic has two systems for the sky/weather: a 2D Time of Day (TOD) system, and a 3D dynamic system using SilverLining.

The 2D system is from the original Train Simulator Classic release and comes with several limitations. Firstly, the lighting, sun/moon trajectories, and sunrise/set and moonrise/set times are all set on a per-season basis for one specific latitude, meaning any scenario set as summer will have the exact same sun/moon trajectories and timings. This particularly becomes an issue for scenarios set in winter months, where the sun should set between 4pm and 5pm (in the UK), but the season chosen in the scenario is spring to prevent there being snow on the ground, which gives a sunset time of 5:45pm. On the contrary, the 2D system is visually far more flexible and customisable, which is why Armstrong Powerhouse use it for their Sky & Weather Enhancement Pack 2.0.

The 3D system was introduced in Train Simulator 2015 under the Dynamic Clouds option. It improves upon the 2D system by dynamically setting the sun/moon trajectories and timings based on the scenario date and location, as well as having actual 3D clouds which move and cast shadows, compared to a static texture for the 2D system. However, it has less customisation and has other limitations, such as clouds not rendering in the distance.

This program gives you the best of both systems by combining the superior visuals and choice of sky/weather from the 2D system with the dynamic nature of the 3D system. This provides the most realistic sky/weather representation in Train Simulator Classic. Using the Sky & Weather Enhancement Pack 2.0 from Armstrong Powerhouse as a base (required for this program to function), it allows you to select which scenario you want to drive before you load it and updates the sun/moon trajectories and times to match the scenario date and location, just like the 3D system does by default. It will also set the lighting, sky colours and adhesion (on Armstrong Powerhouse rolling stock add-ons) to match the scenario date, rather than it being based on the season that is chosen in the scenario editor. For example, if you have a scenario with a date in January (northern hemisphere), but the season is set to spring so that there is no snow on the ground, the program will use lighting, sky colours and adhesion that is applicable to winter, rather than spring, to make it even more realistic.

The table below shows which lighting, sky colours and adhesion will be used, based on the scenario date.

There are a number of factors which could cause a specific route or scenario to generate an error message when using the program. Whilst the program has been thoroughly tested on multiple systems, it is impossible for us to test every route and scenario combination, so if you encounter any issues whilst using the program, please fill out the Google Form here, providing as much detail as possible.

Changelog

v1.0.0 – Initial release.

v1.1.0 – Various fixes and improvements based on user feedback, including:

  • Routes and scenarios without an English display name should now be listed
  • Route and scenario names are now listed in the language the game is set to use in Steam (if the content has been translated to that language)
  • Extra white lines in the route and scenario lists removed
  • Attempts are now made to parse malformed XML files, reducing the number of errors when loading routes/scenarios
  • XML files in the wrong folder location should now be ignored in most cases
  • Added an option to have Lua scripts updated automatically when the program loads, so you don’t need to remember to press “Update Scripts” after installing/updating AP products
  • Added an option to set your RailWorks install path in the Settings window, rather than it relying on the install path set in the registry
  • Added an option to choose between light/dark mode, rather than it relying on the system setting
  • Relaunching Train Simulator Classic shouldn’t open a second window of the program if you hadn’t closed the previous window

v1.2.0 – Various fixes and improvements based on user feedback, including:

  • Fixed an issue where routes that directly reference the AP TOD files were unable to be selected with a file not found error
  • Fixed an issue when the TOD files referenced by a route differed between the route properties file and the route template file which meant the TOD didn’t update
  • Added a pop-up message when selecting a scenario that uses TOD files from Kuju/RailSimulatorCore that requires the simulator to restart
  • Fixed a crash if your Steam app manifest for TS had missing language fields
  • Added check to stop multiple instances of the program opening

  • Steam should no longer register that the program is part of the game itself, meaning it should now be possible to restart Train Simulator Classic from Steam whilst keeping the program open
  • Moved all options to the Settings window
  • Added a new option to automatically close the program when TSC is closed
  • Added a new option to enable logging if asked to by support

v1.2.1 – Various fixes and improvements based on user feedback, including:

I'm writing a second comment, I checked the program's operation. Now I can believe that it's autumn in the 1D66 scenario from HST (MTU), and at 19:00 it's already completely dark. Thanks again, I've been missing this for a long time!

Funnily enough I think that was one of the scenarios I tested an early version of this on a couple of months ago! It's amazing how many scenarios we drive in daylight when realistically it should be dark. On the other hand though, if you're driving a summer scenario in Scotland without this program, it gets dark up to an hour and a half too early, but that's all rectified with this. Glad you're finding it useful!

Also apologies if you got notified for my reply to Shamus just now. TSC doesn't allow you to reply to replies, so I had to add another reply under your original comment (like he did).

Avatar of Average Enjoyer 777

ChiefJack, It's okay, I don't get notifications anyway, thanks again! And do I understand correctly that this program is not suitable for German routes? The program gives me an early dawn at 12:00 with my IKB4 route (update of IKB3) in quick drive

Avatar of ChiefJack
ChiefJack 16 Feb 2025

It is suitable for any route. However it won't work in Quick Drive because Quick Drive scenarios do not show up in the scenario list like Career, Standard and Free Roam scenarios do. They are made by the simulator when you click to load into them, so it's not possible to select them beforehand. Are you also getting that issue when trying a Standard scenario on that route?

Avatar of Average Enjoyer 777

Ohh, sorry, I mean Free Room scenario, not quick drive, mistake

It should work fine for a Free Roam. Do you have a link to the route at all?

Avatar of Average Enjoyer 777

I'm sorry to mess with your head a little, I'm working on improving the IKB3 route, the route was copied a little crookedly, as it turned out, and the coordinates flew off. They were 0/100. I set the coordinates of the original route and everything worked perfectly.

Hello possibly a stupid question can you still use the weather extensions from the AP weather ep 2.0?

Avatar of ChiefJack
ChiefJack 16 Feb 2025

Yes you can. This program won't affect the weather component of the AP EP in any way, it just edits the sky component for the selected scenario. Those are two separate components of the AP EP so weather and weather extensions will still work as normal.

Avatar of ChiefJack
ChiefJack 18 Feb 2025

The program finds every file named RouteProperties.xml that's within your RailWorks/Content/Routes folder and lists them in the route section. Similarly, once you select a route, it finds every ScenarioProperties.xml file within that route folder and lists them. This includes files that are within ap files. I don't really own any German content but the filenames should be the same in English and German otherwise the game wouldn't work. Do all the routes/scenarios show up in other third party tools like TS Tools and LocoSwap?

Avatar of ChiefJack
ChiefJack 18 Feb 2025

Paul, I think that is quite an extreme comment. Given that hundreds of people have used this and not had it freeze their PC, it suggests you have done something wrong when using the program.

Anyhow, to remove the program, delete this folder: RailWorks/plugins/AP Sky Accurate Time of Day

Paul, if you're still having it freeze after removing the program, it's clearly nothing to do with using this program because all files related to it have been deleted. If it's just one specific scenario, then it's an issue with the scenario (or perhaps some of the trains used in the scenario).

I think the program does not recognize if you have a clone of a route. In my case all cloned routes are missing. Perhaps you can fix this, so that this mod could be used with all routes. That might be perfect.

The program should work with all routes, including clones. It finds every file named RouteProperties.xml that's within your RailWorks/Content/Routes folder and lists them in the route section.

That error means that the RouteProperties.xml files for those specific routes aren't valid xml files, usually because they're corrupt or have invalid xml characters. The program will still run fine if you dismiss the error, you just won't be able to use it on scenarios for those routes. If you want to clear the errors, you'll have to find those files and correct the issues in them.

hi, does this program install the AP weather files to ALL routes (as long as you own the AP weather pack) or only the routes specified in the AP weather manual. If the route is not listed in the AP weather manual does this pack still work on that route? Many thanks

Avatar of ChiefJack
ChiefJack 12 Mar 2025

Hi, when you select a scenario, it will put the AP sky on any route, even if it's not listed/supported by the AP SWEP by default. Then when you deselect the scenario after driving it, it will revert the sky back to whatever it was before. So back to the default AP sky if on a supported route, or the default DTG/Kuju/other devs sky if on an unsupported route.

So yes, in summary, this program will work with any route, even if it's not one that's supported by AP.

I have noticed that Mount Shasta Route with my enhancement patch is listed twice in the route list. Looks like my patch makes a false positive somewhere, however I dont have any idea what can trigger this. Can you please take a look?

The patch is here:

Avatar of ChiefJack
ChiefJack 17 Mar 2025

Hi, I don't own that route, but I've just downloaded your patch and had a look at the files. It appears that you're re-distributing the RouteProperties.xml file for the route in your ShastaRouteEnhancementsScenarios.ap file which goes in the route folder. Hence the program will be picking up the RouteProperties.xml from the main route ap file, and then also from your ap file.

If you're wanting to redistribute that file so that the route uses AP skies, you should include it as a file in the route folder itself. That way the program will only detect that version, and it also removes any chance of the sim getting confused with which version to pick as well (the sim is likely to randomly pick either the default or your updated one when they're both in an ap file, but if it's outside any ap file, it will always pick your updated one).

Avatar of Ingwar
Ingwar 17 Mar 2025

Thank you, that fixes the problem! And I did not know about that random selection. Wanted to keep things clean, but it looks like it leads to some potential problems. And thanks again for the explanation.

BTW how do you get information about some route position on Earth surface (or just getting information about its location relative to the equator)?

Avatar of ChiefJack
ChiefJack 17 Mar 2025

Glad to hear that fixed your problem. The program gets the location information by reading the ScenarioProperties.xml and seeing where the scenario marker has been placed for that specific scenario.

This mod doesn't change the sky colours from the original SWEP from AP - it just adjusts the timings for things like sunrise, sunset, moonrise and moonset, and then the sky colours match the date of the scenario rather than the season, but all using the original colours.

Have you checked also to see whether Windows Defender is quarantining it? In Norton, can you restore the program files from the quarantine area to fix it? I used to have Norton installed but found it to be more of a nuisance than an aid so removed it myself - I just stick with the basic Defender offering these days.

I'm having the same issue with McAfee. ATS and AP downloads are being tagged as viruses. It's probably the Antivirus suites giving false positives, rather than a real issue. I emailed AP and they said that it's undoubtedly the case. With McAfee, I can restore the quarantined files and mark them as safe, so that I can run the installers.

Dunworkin2, indeed that’ll be the case. Sadly, unless people pay several hundred quid a year for a certificate, AV software will generally block programs even when there are no issues with it at all. For individuals releasing free software like myself, it’s unjustifiable to pay that unfortunately, meaning some users run into issues with their AV software reporting a false positive. Thanks for your understanding though.

HI, No I get a "whoops" error this file cannot be restored message every time I try to restore and create exception. I don't understand how it doesn't pick up error when downloading, or even installing. It's only when I start to load TSC it pops up and moves it to quarantine asking me to restart PC. If I close the message, the game loads and plays but I cannot use this add on.

Hi Miguel, that suggests it might be trying to quarantine the launcher.exe file which is located in the Config folder for the program. Have you made an exception in Norton for that file, as well as the main program exe?

Avatar of Miguel
Miguel 21 Jul 2025

I'm at a loss tbh mate. I've created an exception for the launcher.exe in the config folder but it still insists on placing it in quarantine every time I run TSC. Like I say it's strange it doesn't pick it up when initially downloading it or the initial install, just opening the game. Even tried disabling aspects of Norton but it's the same result.

ChiefJack 21 Jul 2025

I’m at a loss too unfortunately. It seems very weird that it’s removing an excluded file, I can’t even see anything on Google about others having the same issue. Final thought, have you tried excluding the whole folder?

Miguel 22 Jul 2025


This is what I get. Tried the full folder but same result.

ChiefJack 23 Jul 2025

Hi Miguel, this is very odd. Could you try filling out this form from the Norton website to tell them that they're wrongly reporting the exe as a false positive: https://submissions.norton.com/reportfalsepositive#pc
I doubt they'll doing anything but it's worth a go.
I'm also sure you've already done all this, but I asked ChatGPT for ideas and it suggested that you need to make a couple of different types of exceptions for the program: https://chatgpt.com/share/68813b1d-ac44-800c-b91d-549e97a9c360

Hi mate. I don't know how or what has happened but it is now working without any issues. I'm not aware of any updates to either my PC or Norton. I tried many things myself and each time started TSC. The last thing I tried was a reset of Norton which seemed to do the trick. So I'm now happy. Thanks for taking the time to help mate, much appreciated. Great work, it adds so much more realism.

Hi, this is a known issue with the template route file that is included with SWEXR. I have previously notified Just Trains of the issue and am awaiting a fix to be released from them. In the meantime though, you can drop in this file to fix the issue: https://drive.google.com/file/d/18lXJIjv2L49mo0KCQYyZ6KErPG5HHGoP/view?usp=sharing

This has generally been a very nice mod but I'm not sure its working with some routes.

Hi Jack

Hope you are well, i have just installed the Barnstable to Exeter route by DPS, the route loads fine however i am getting the following error. Once I click ok the app still lets me select the scenario and sunrise/sunset times are displayed.

Avatar of ChiefJack
ChiefJack 2 Nov 2025

Hi, this just means that one of the scenarios that you have installed for the route has some corruption, meaning the program can't read its data properly. This means that it won't be displayed in the list of scenarios to select. All other scenarios for the route will be fine and can be selected as normal - it's just one specific scenario that won't be available to select. Hope that make sense!

Avatar of Dkentflyer

I just installed this, before I start using it I wanted to ask, once the game is open and your scenario is selected, can you safely close the program window, or does it have to be open the entire time you're playing?

Avatar of ChiefJack
ChiefJack 23 Nov 2025

The program was designed to be kept open whilst you're driving a scenario, but in theory it should still work fine if you select a scenario, close the program, and then drive the scenario. Closing the program won't deselect the scenario so you will still see the correct TOD updates. When the program is next opened, it will effectively deselect the scenario and revert the files back to normal. So yes, you should be able to select and then close the program for each scenario you drive. Hope that helps!

Avatar of Matty_1843
Matty_1843 23 Nov 2025

Thanks Jack! Only reason I brought it up was because I've found sometimes when I try to record a clip in the game with another window open, it sometimes records that instead, so I was hoping to avoid that while using it. I'll let you know if anything happens when I try it out.

Hi Jack, sorry, had to make a second comment because it won't let me post images in replies, something's happened, I've been using the program fine for a couple of days, but now AP weather on JT South Western Expressways is broken. Any other weather works fine (although it looks terrible), and it seems exclusive to SWEX, it hasn't happened to other routes I've used the program on, or other JT routes. I tried copying the TimeOfDay folder from APWeather to SWEX thinking the original had been deleted, but no change. Do you have any idea what's happened? I installed the template fix and did a scenario on SWEX with no problems yesterday.

ChiefJack 26 Nov 2025

Hi Matty, please could you confirm whether this is the original SWEX route, or the newer extended SWEXR (SWEX to Reading).

Oh, it's the newer one to Reading, sorry, should've mentioned that. I checked Midland Main Line too, that's unaffected, so doesn't seem like a Common Library issue.

I've just tested my end and all is working fine. May I ask if you're seeing the fully black route with or without a scenario selected in the program? Please could you enable logging in the program settings and then try to select a scenario on the route. Then could you DM me the log on Discord (chiefjack_). If you don't have Discord, please could you fill out the support form and provide me some other means of contacting you.

Avatar of ChiefJack
ChiefJack 18 Apr 2026

For the Birmingham 2010 route, it looks like the scenario markers have for some reason been placed many 1000s of miles away from where the route actually is. So much so that the latitude for them is 103.625... - latitude only ranges from 0-90. Therefore, even if it didn't have that error message, the timings used would be completely inaccurate. It's a scenario issue, not a program issue.

For the Marston Vale one, I'm going to need more information. It's likely a scenario issue, but that scenario doesn't appear to come with the route, and I can't find it online anywhere.

Hi Paul, sorry but I have no idea what you mean here. As I've said already, I've checked to see if the scenario is one that comes with the route, which it isn't, and you don't seem to know where it is from either, which means I can't really be of much help to you. If you can give me a link to download the scenario I can have a look at this further, but otherwise there's nothing I can do sadly.

Hi Jack.

I've never had any problem with this program until the last update. Now it will only change the skies if I select the scenario from the plugin whilst the game is already running. I can't get the plugin to apply to any of the routes with Kuju files because it makes me restart the simulator and that somehow disrupts the plugin.

Hi Ryan, apologies for the late reply. This was caused by the recent update to the SWEP, and could only be fixed by AP. I’m pleased to say that AP have updated the SWEP today, so if you redownload that, and then reinstall this plugin, it should hopefully work again. I haven’t been able to test this though, so if you could let me know how it goes, that’d be appreciated. Thanks.

Hi Ryan, that looks like an internal issue with the code whilst it’s trying to calculate the timings for that specific scenario. If you fill out the support form linked in the description with some more details about the scenario, and leave me a contact method (email, Discord etc), I can get you to send over a copy of the scenario for me to debug. Thanks.
