This railroad, after putting Alco trucks with GE motors under some of its EMDs, put Baldwin trucks with Westinghouse motors under some of its Alcos.
The only railroad that comes to mind is Soo Line.
Soo put the trucks from 21 of its 22 Alco “Road-Freight” (FA1) engines under GP30s 701-721 (700 got a spare pair) with the trucks from the 22nd going under GP35 722. At about the same time, the funky A1A tucks under RSC3s 372-374 and 2380 were replaced by Baldwin trucks from DRS-4-4-15s or AS16s. Even though the rebuilt Alco trucks lasted until the units were retired in the 1990s or later (715 is still operable) they were considered to be troublesome in winter. The retrucked RSC3s only lasted a few years working as switchers away from the light track that they were purchased for.
In your court, Paul.
In a similar vein, this railroad re-powered some of its Alco power with EMD engines, the Alco engines were then used to re-power some EMC switchers. Which railroad is it and what further modifications were made to the re-powered Alcos?
Sounds like the Roach Island. Frisco and Katy did it , too, but did not own any EMC as far as I know. The further mods? eh. That I don’t remember.
You’ve got the railroad correct. Further modifications are still open.
CRI&P put Blomberg trucks under their humpbacked, re-engined FA1s.
We have a winner. rcdrye, your question.
After the last question we’ll be TRUCKING along!! 
Each train set of this pair of postwar streamliners was expected to make a round trip per day. The First-Class equipment on the train was named after the trains’ endpoints.
Monon - Hoosier and Tippecanoe
Mark
The Hoosier and Tippecanoe were each named after ONE end of their run. The first-class cars on these trains were anmed after BOTH ends, with each train getting one of the cars. Both trainsets served the same endpoints.
C&EI - Meadowlark and Whipperwill
Mark
I made a small mistake in posting the original question. Initially the train sets each made 1 1/2 round trips per day (giving three round trips with the same train names), though the service was cut back to two round trips only a couple of years after it was inaugurated. Each train set’s first class car was named after one of the endpoints. The cars were carried in the same trains after the service was cut back to a single round trip, and even operated briefly on the Amtrak service of the same name. The train name described a characteristic of the service, shared with one other train pair operated by the same railroad.
Rob:
GN’s “International” trains with the “Port of Seattle” and “Port of Vancouver”. The second part of the question should be the “Winnpeg Limited”.
Ed Burns
Ed has the answer. The common part with the “Winnipeg Limited” is that the “Streamlined International” was international as well. The two observation cars were used on the “International” until 1971. Both were bought by Amtrak in the second wave of equipment, and used briefly on the “International” when it was started again in 1972, before ending their careers in Milwaukee-Chicago-St. Louis service.
Rob and All:
The BN merger was in 1970. They repainted about 25 passenger cars before discontinuing the project. What was the reason for that and how many heavyweight cars were repainted? Numbers of those cars are optional.
Ed Burns.
They did not need to repaint any stainless steel cars. The NP and GN had painted lightwieghts that were repainted into BN green, and the program was halted because of the pending AT&SF to BNSF merger, but I believe the only heavyweight cars repainted were their business cars. I do not know how many or what their numbers were, but other than business cars, they would only have repainted liightwieghts -or heavyweights repainted for MoW duty.
Dave:
Not even close. Think 1970 and not the 1995/6 merger of the BN and ATSF.
Ed Burns
I would guess the heavyweights were for the last storage mail contracts, and repainting stopped when the contracts were dropped. The renumbering and repainting of other cars stopped in early 1971, after NRPC (Amtrak) ID’d the cars it wanted.
