This is a GE ES44AC Physics Modification pack for the Norfolk Southern Heritage SD70ACe locomotives.

In order to utilize this freeware physics upgrade, you must have purchased the "Norfolk Southern Heritage SD70ACes Loco Add-On" pack available at Steam: http://store.steampowered.com/app/222543/

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 UPGRADE PACK. Physics adjustments made around the existing sounds.

The purpose of this pack is to adjust the locomotive weight, fuel capacity, motor amperage limits, and traction and braking effort values for more realistic operation.

General Parameter Change Log (same for all three locomotive classes):
1. Set fuel tank capacity to 4,900 gallons.
2. Changed HUD ammeter function so that it displays tractive/braking effort in thousands of pounds. This means that if the HUD ammeter reads "157 Amps", the locomotive is putting out 157,000 lbs of tractive effort. Conversely, if the HUD ammeter reads "-34.52 Amps", the locomotive is putting out 34,520 lbs of dynamic braking effort.
3. Adjusted tractive effort ratings and curves for individual locomotive models based on the specifications listed below.
4. Adjusted dynamic brake effort ratings and curves for individual locomotive models based on the specifications listed below.

Specific horsepower and tractive effort ratings used in calculation for individual locomotive models:
1. EMD SD70ACe (EMD 16-710G3C-T2; 4500 GHP)
 a. Starting tractive effort of 189,000 lbs (840.714 kN) up to 7.646 mph.
 b. Traction horsepower at wheel is 4,185 hp (3,123.134 kW); efficiency rating of 93%.
 c. Max Dynamic Brake effort of 105,000 lbs (467.063 kN) from 18.395 mph to 3 mph; linear fade from that speed to 0 lbs @ 1 mph.
 d. Dynamic Brake horsepower at wheel is 5,145.6 hp (3,840 kW).
 e. Increased weight of 190.51 metric tons (420,000 lbs).
 f. Maximum speed of 75 mph.
 g. Fuel consumption @ notch 8 is 187 gallons per hour.

IMPORTANT; Install Instructions

1. Locate the RSC assets folder (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\RSC\ES44NSHP)
2. Open Railworks_NS_Heritage_ES44AC_Physics_Mod_Pack.rar
2a. Before proceeding to step 3, make sure your "RSC" folder is NOT set to "read only". You can change the folder settings using the properties function. IF the "RSC" folder is read only, the files will not overwrite existing files when you attempt step 3.
3. Drag the file folder from the .rar in step 2 into the directory you opened in step 1. Overwrite if asked.
4. The installation should be complete. Run TS2015 to check.

Thank you for downloading and installing.
Enjoy =)
