Another big difference between Gen 1 and Gen 2 was the air intake system. Gen 1 had multiple hood louvers while Gen 2 had a centralized intake.

The ironic thing is some of the FTs parts are still running around for now at least on the railroad. Most of the Santa Fe trade ins for GP 30s and 35s were built using recycled FT trucks that had been made in WW2. So if it’s a former GP 20 -35 in your fleet with Santa Fe heritage more than likely the trucks have a casting date from the early 40s on them.
Just a little bit of history there.

No worse than my ‘favorite F units’… what if you built an F45 with a proper bulldog nose?

)

No, the Australian CL series. You may remember that the replacement for the passenger Es after 1964 was the FP45/SDP40F with its angular nose. The Australians kept the bulldog nose with the newer carbody and 645 power – best of both worlds.

Very quickly ‘improved’ with better 6-cylinder tugboat engines into the RT-624, with 2400hp and (ultimately) trimounts –
But not as oddball as the Lima version of that transfer unit, though…
which had 2500hp in 1950…
(Note the snazzy builder’s plate on the cab)

The Lima was actually a pretty good unit. Great photo.
I always found the Baldwin and Lima centercab transfer units intriguing. Too bad that I never saw one.
The Fairbanks-Morse H24-66 “Train Master”, introduced in 1953, was the premier high-horsepower diesel-electric locomotive of its era, producing 2,400 hp (often referenced near 2500 hp in discussions). It was the most powerful single-engine locomotive when built, featuring a 12-cylinder opposed-piston engine and a 6-axle design, though its complex maintenance hindered widespread adoption.

God please let someone make these in plastic in HO scale…..
I know, wrong forum.
But it wouldn’t be long before Alco developed the intercooled 16-cylinder 244H engine for the RSD-7, the first-generation visual equivalent of the SD90MAC/SD70ACU. Demonstrators (DL600/601) by January 1954 at 2250hp each; quickly boosted to match the FMs.
The nearly-identical locomotive with the new and improved 251 was the RSD-15. Penn Central, in a somewhat misguided attempt at frugality, re-engined one of these with an EMD engine to be a slug mother (9949, I think)..
Somehow, the meaning of the thread title escapes me. Someone please clarify. Thank you.
It was one more try to have the equivalent of the MR cafe. As on there, the theme its denizens change from month to month.
