well as usual I turn to you guy’s
how can you tell I just got a sweet rs and was just trying to find out what’s the differance from rs-1 rs-2 and so on
Ken[B)]
Do you mean apart from their obvious differences in appearance?
RS-1 is square looking (hoods), has a cab overhang
RS-2 and RS-3 are similar. More rounded, no over hang.
RSD-4/5 has 3-axle trucks.
RS-11 is easy - high hoods, notches where the number boards are…
I don’t get why its hard to tell the differences. Its extremely simple.
RS10 is a Canadian Model with no notches on the hoods (as is RS-18).
RSD-12 is essentially an RS-11 with 6 wheel trucks.
Ironically, RSD-7, which was longer than RSD-12 was also more powerful (2250 HP vs. 1800 HP).
'Course you could always look it up on the 'net. Kinda like this: http://www.northeast.railfan.net/diesel7.html
Great place the 'net. Information out the ying-yang.

You really need a copy of 'The Second Diesel Spotter’s Guide" It contains
all that information you’re looking for. Or the new updated version called,
I believe, Classic Diesels: the First 50 Years , or something like that.
This might help:
just what the doctor ordered
COOL
thanks for the info
Actually, there were also low (short) hood RS-11s, then there was the RS-27 & RS-36 too (basically higher horsepower RS-11s with low short hoods).
RS-1 and RS-2 had the fuel tank under the cab and the fuel filler in the side of the cab.
Morrison Knudson rebuilt some of the RS-3s with EMD prime movers and low short hoods, known as the RS-3m.
Immediately after the end of WW II, the American Locomotive Company (ALCO) produced the RS, Road Switcher Diesels. The third version, the RS-3 ,was first delivered in 1950 to the Great Northern Railway. Over 1,272 were built by ALCO. RS-3’s have been used in local freight train service as well as commuter passenger service. The RS-3’s ran throughout the US, Mexico, Cuba, Canada, and S. America. Production of the RS-3 ceased in 1956
THe New Haven after getting RS-2’s had the specs for their RS-1’s changes.
THe NH had the RS-1’s fuel fill moved OFF the cab.
They didn’t like the fuel spill on the cab of the RS-2’s.
