This is the Amtrak GE P30CH (Pooch) Physics & Sound Modification pack version 2.5 In order to utilize this freeware physics upgrade, you must have purchased the "Train Simulator: Amtrak P30CH Loco Add-On" pack available at Steam: http://store.steampowered.com/app/277...


This is a freeware pack; in no way is it to be used for commercial purposes. You are free, however to further modify the physics enhancements found in this pack for personal use if you so choose.


Version 2.0 update includes sound mod by Railworks America User Callum Beatson aka "StrategyFirst". Prime Mover sounds have been updated, and two horns + new bell have been provided as well. To switch between the horns, follow the instructions provided in the user manual below.


Version 2.5 includes the signature JohnS Brake fix.


The purpose of this pack is to adjust the physics performance of the locomotive.


List of changes:


  1. Modified tractive effort and braking effort curves.

  2. Modified power ratings @ alternator and @ wheel

  3. Set fuel capacity to 3600 gallons.

  4. Set weight to 386,000 lbs.

  5. Removed coupler slack.

  6. Adjusted rpm range and rate of change.

  7. Adjusted locomotive load response times.

IMPORTANT; Install Instructions


  1. Locate P30CHPack01 (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\DTG\P30CHPack01)

  2. Open DTG_Amtrak_GE_P30CH_Physics_and_Sound_Mod.rar

  3. Drag the file folders from the .rar in step 2 into the directory you opened in step 1.

  4. The installation should be complete. Run TS2016 to check.

  5. If installation is botched or does not work, to back up to original files, delete the folder from step 3.

User Manual: Once installation is complete, the default horn that is being used is Horn


  1. In order to change the horn that is used, follow the instructions below:

  2. Open folders until directory reads "C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\DTG\P30CHPack01\Audio\RailVehicles\Diesel\P30PH\Exterior"

  3. You will see two folders; "Horn 1" & "Horn 2"

  4. Open the respective folder that contains the files you want to use and copy them (CTRL + C).

  5. Proceed back to the directory from step 1a.

  6. Paste the selected files (CTRL + V); overwrite when prompted

  7. Horn swap should be complete. Run TS2016 to confirm.

Thank you for downloading and installing.


Enjoy =)
