This pack offers you scratch-built models of EMD GP7 and GP9 locomotives in two Pennsylvania liveries. This should cover most of the freight roster of the PRR's GP7 and GP9 units. I tried my best to get the roster numbers correctly assigned to the versions with and without dynamic brakes but am not entirely sure that I have got it right.
This locomotive was built from parts of my earlier SD7 model and has essentially the same functionality: basic cab controls and TS12 effects, but there aren't any advanced scripting features like for instance a start-up sequence. The models feature custom couplers, dynamic numbers (real roster numbers), light effects and window rain effects, animated wipers, and cab controls.
The animated roof fans were modeled by Dan Vystrcil of Virtual Rail Creations and are used with permission. To see more of the fantastic VRC models, please stop by at their website: http://vrailcreations.net/
The engine comes ready to run with its physics and simulation parameters based on the default F7, so it will perform similar to it (albeit a bit more powerful, the GP9 being a bit more powerful than the F7). Sounds are also aliased to the default F7. Please note that due to these aliased components, you must own the US Loco & Assets Pack: http://store.steampowered.com/app/208306/, which most users will already have. See below for more details.
