TS2015 DTG CSX NRE 3GS-21B Physics Mod Pack

This is the DTG CSX NRE 3GS-21B Physics Modification pack version 1.0

In order to utilize this freeware physics upgrade, you must have purchased the "Train Simulator: CSX NRE 3GS-21B 'Genset' Loco Add-On" pack available at Steam:

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.

This is NOT a sound mod pack. Physics adjustments made around existing sounds.

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

List of general changes; specific changes for each specific locomotive located below:

  1. Modified tractive effort curve (

  2. Modified power ratings @ alternator and @ wheel.

  3. Removed "Field Divert" function to unlock maximum performance potential.

  4. Modified weights.

  5. Removed coupler slack.

  6. Adjusted rpm rate of change.

  7. Adjusted locomotive load response times.

  8. Adjusted fuel consumption (

Technical specifications:

  1. NRE 3GS-21B (3x Cummins QSK19; 2100 BHP)

    1. Starting tractive effort of 80,386 lbs (357.575 kN) up to 7.5 mph.

    2. Continuous tractive effort of 46,044 lbs (204.814 kN) @ 12.5 mph; 8,500 lbs (37.81 kN) @ 65 mph.

    3. No Dynamic Brake

    4. Maximum speed of 65 mph

    5. Engine RPM range = 650 - 2100

    6. RPM change rate (rpm/second) = 100

    7. Fuel consumption range (gph)= 2.5 - 112

    8. Weight = 268,000 lbs (121.564 metric tons)

    9. Fuel capacity = 2900 gallons

    10. Max traction amps = 1500

IMPORTANT; Install Instructions

  1. Locate GensetCSXPack01 (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\DTG\GensetCSXPack01)

  2. Open DTG_CSX_NRE_3GS-21B_Physics_Mod_Pack.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 TS2015 to check.

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

Thank you for downloading and installing.
