Nostalgia & History > Questions about carbody dieselsDate: 01/19/22 22:31 Questions about carbody diesels Author: Sp1110 Why didn't Southern Pacific or Pennsylvania Railroad order the F9 or FP9 locomotives?
How many heavyweight passenger cars can be pulled by one F9? When did the last F Unit pull a freight train on a Class 1 railroad? Edited 4 time(s). Last edit at 01/20/22 21:15 by Sp1110. Date: 01/19/22 22:41 Re: Question about carbody diesels Author: radar The F9 overlapped with the GP9, and SP bought a lot of the latter. That's when a many railroads began to see the wisdom of the road switcher. Besides, they also had a pile of F7 units.

The minor advantage of walking between units at high speeds in carbody units is more than offset by the difficulty in getting on and off them. Then comes the difficulty in working on the engine in a carbody. G Date: 01/20/22 21:02 Re: Questions about carbody diesels Author: Lurch_in_ABQ Function beats form.
Date: 01/21/22 14:54 Re: Questions about carbody diesels Author: NCA1022 Weren't GP-9's less expensive to purchase than an F9? think I read somewhere that the F-unit carbody was more expensive to fabricate / form and that the equipment layout of the Geeps took less labor to assemble on teh shop floor. Is this right?
So initial cost could also be a factor in addition to the operational ease of using Geeps to switch and the easier maintenance with Geeps vs. wrestling with repairs and parts within the confines of the F-unit carbody. - Norm Date: 01/21/22 17:20 Re: Questions about carbody diesels Author: Sp1110 Why was there no F unit carbody version of the GP40-2 or GP38-2?

In my previous post, I failed to ask about the speed restriction when running a carbody unit backwards. G Date: 01/21/22 19:40 Re: Questions about carbody diesels Author: Coast On the Santa Fe of the 1970-1990s a car body , or a comfort design cab when backing maximum speed is 45 mph

Date: 01/22/22 08:35 Re: Questions about car body diesels Author: Sp1110 So you are saying that a non-comfort cab unit like a GP50 can go in reverse faster than 45 mph?

I belive they got retrofitted with conventional control stands.

Even in their final days before refurbished they ran like EMD's should run. The refurbished engines run like crap. Worse yet are the refurbished 500 class GE's. Used on locals and yard service; they aren't much better than Gensets.
