This pack is a complete rework of the RSC P42DC locomotive and rolling stock.

For this pack to work you must install the “Amtrak P42DC 'Empire Builder' Loco Add-On”, which you can buy here:

I made a YouTube video of this pack, if you want to see it in action:


Version 2.5 Changes:
- Tweaked the prime mover sounds.
- Included the emergency brake’s air release sound.
- Tweaked the locomotive textures, especially on the trucks.
- Improve the effectiveness of the independent brakes.

GE 7FDL-16 prime mover sound in normal mode (200-1047 RPM) and HEP mode (900-908 RPM):

The sound is directly linked to the RPM. So, for the HEP engines I gave it 1 RPM per throttle notch. That way you can hear the change in sound according to the throttle position. As you give it more power, the rhythm/beat of the engine stays the same as in real life (900 RPM regardless of throttle notch). But the base sound becomes more powerful and the engine sounds “grouchier”. Also, when you have non-HEP and HEP engines combined, the sound from the HEP engines will overpower the much quieter non-HEP engines. That is until the non-HEP engines surpass 900 RPM (notch 7 & 8). Then, they become KING!

HEP Implementation (Same as before):
For simplicity of installation, I made the non-driver engines operate in HEP mode. Since Train Simulator doesn’t implement HEP loads according to the type and length of a consist, I decided to simulate an 800-kW load, which takes 1072 hp from the engine. On HEP mode, the engine runs at a constant 900 RPM, regardless of throttle position. This limits the power output to 3655 hp, without a HEP load. When you add an 800-kW load, it reduces the power available for traction to just 2583 hp.

If you try to tinker with the power settings in the engine’s configuration file, please bear in mind that according to the “Train Simulator Developer Documentation” (Available here: http://tscdevdocs.co.uk/reference-manual/blueprint-editor/diesel-simulation-blueprints/diesel-electric-subsystem.html#TOC-Diesel-Electric-Subsystem), engine power values are expressed in kW and tractive effort in kN.


1. Go to your Rail Works directory
(Typically: C:\Program Files (x86)\Steam\steamapps\common\RailWorks).

2. Drop the “Assets” folder in the directory (Overwrite the previous version).
3. Make sure that you set the in-game “Ambient Occlusion” to, at least, the “Low” setting (Preferably “Dynamic”).

And that’s ALL you have to do.
