This is the DTG Soldier Summit Locomotive Physics Modification pack version 1.0

In order to utilize this freeware physics upgrade, you must have purchased the "Train Simulator: Soldier Summit Route Add-On" pack available at Steam: http://store.steampowered.com/app/277775/

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 full sound mod pack. That full mod pack MAY be available separately from this one (if I deem it necessary to create one).

The purpose of this pack is to adjust the physics performance of the three diesel locomotives that come with the DLC (EMD GP9, EMD SD40T-2, & EMD F40PH-2).

List of general changes; specific changes for each specific locomotive located below:
1. Modified tractive effort and braking effort curves.
2. Modified power ratings @ alternator and @ wheel.
3. Modified fuel capacity.
4. Modified weights.
5. Removed coupler slack.
6. Adjusted rpm range and rate of change.
7. Adjusted locomotive load response times.
8. Created F40PH HEP mode locomotive ("nd" unit).
9. Fixed botched notch 8 values in F40PH engine sound proxyxml files.
10. Fixed botched idle & notch 8 values in GP9 engine sound proxyxml files.

IMPORTANT; Install Instructions

1. Locate SoldierSummit (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\DTG\SoldierSummit)
2. Open DTG_Soldier_Summit_Loco_Physics_Mod_Pack
3. Drag the file folder 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 folder from step 3.

Thank you for downloading and installing.
Enjoy =)
