Do the GP40MCs have 16-645E3s? The F40PH-2Cs have 16-645E3s and they sound like 710s when starting up while the GP40MCs sound like a geep starting up. (starting up from being off)
The F40PH-2Cs are said to have 16-645E3Cs, but according to Wikipedia the 645E3C was only used on the British Class 59 and would have to be rated at 3300HP.

The information on that page is of dubious quality. Just as an example, a book of mine lists the SD40-2 as having an 16-645E3C prime mover, and I'm sure there's others if I want to look through it. It's also unclear if the horsepower rating on that page is for the horsepower available for traction or the engine's total horsepower output (in general, locomotive prime movers generate 300 horsepower more than the locomotive itself is rated at, with the excess used to power the locomotive's auxiliary systems).

There is two doors in the nose, so in a collision it wouldn't make it into the cab. That's the most crazy reason I have heard. WHERE did you hear that???
Umm, it's someone that you probably know and respect who was probably just screwing with me. I'm not going to name him in public. He's also the guy who told me that the doors were welded shut (for that reason)

What are max speed theses engines can go outside of the Cars?? I hope nothing crazy like 100 mph that is over kill for a Geep!!

I don't know what the gearing is for the MCs but I can definately remember them having to be regeard because traction motors were being burnt up left and right when the first came around, I have a pic somewhere of one that was heavily damaged by fire in the cab.

Gear Ratio for the rebuilds and screamers from the loco manual is 57:20

How so? Mostly all psgr engines are setup to run max speeds of 100 or so.

I wonder what engine have the fire in the cab and how would you burn up a traction motor??

The Geeps were originally geared for hauling freight. The motors probably didn't take well to having to run at higher RPMs to handle passenger train speeds.

Okay, the engine has RPMs, motors are electric. The engine produces electricity for the motors, the motors turn the gears which moves the axles.

As a Mechanical employee at BET / Seashore life member often says, a locomotive is nothing but a subway car with its own power station (I'll bet anyone else who's active up there will know who I'm talking about :wink:).
