Thank you. I guess the number of engines and the weight of the train load would also have something to do with it.
I am running Trainz 2012, a train simulator game. I am building a custom route based on the Mojave Subdivision in southern California. I have a Santa Fe Superchief passenger train (Pullman stainless steel cars) head by a N & W GP9P doubleheader. 2 each Santa Fe F7 A and B units are pushing this same train. The speed limit for this mainline route is 70 MPH. I like the gear-whir sound from the GP7/9's as the blowers were gear-driven. Same with GM/EMD F7/A7 bulldog nose locos. I like the engine 2-cycle exhaust grunt of the Geeps and TS 12 does a marvelous job at reproducing this sound. The GM/EMD car-body/streamline locomotives of the 50's have the same gear whir sound but not nearly as much grunt as the Geeps.
I ask about speeds wondering if Geeps would have ever cut it for speed on the Mojave mainline doing passenger service.
actually designates this engine for passenger use.
The grades are steep: 2+ % and 2 GP9P's alone had slipping wheels pulling this 14-car passenger consist so I threw so GM F series streamliners on the end for helper duty.
