I have a Jack Pfeifer photo of the 1250 at the Albina engine shop in Portland on May 5, 1969 in fresh paint showing "Road of the Streamliners" lettering on the left side of the cab (long nose is front).
A Ken Ardinger photo dated August 1, 1969 shows it still in fresh paint but back on the Mount Hood branch line with "Serves All The West" on the right side. This was the normal configuration -- different lettering on each side of the cab. Most switchers, though, had 'SATW' on the left and 'ROTS' on the right.
Pfeifer's photo shows a sheet metal plow on the cab end, and Ardinger's doesn't doesn't show one on the radiator end, so maybe the cab end was the front of the UP's only S3.
stefanuccio also what type of truck did the Alco S-3 use ? thanks
also
what type of truck did the Alco S-3 use ?
thanks
In a parallel of the S-2 and S-4 configuration, the Alco S-1 rides on Blunt trucks ("curvy" on the top frame of the truck) while the S-3 has the AAR type A trucks (with a prominent lower straight beam).

hi there Jim
thanks very much for your reply
regards
The engine was built for the Mt Hood Railroad in 1950. UP bought the Mt Hood Railroad in 1968, repainted the engine in 1969, and scrapped it in 1970. I have seen no pictures of that engine, so I cannot confirm what slogan was on that engine. The Atlas model may be wrong, or maybe the UP paint crews used an older stencel that 'fit' in the Alco S-3 cab side...

hi Bill
thanks for your input
From The Second Diesel Spotter's Guide by Jerry Pinkepank:
(The 1000 hp. S-2 and S-4) are distinguished from the otherwise similar 600-hp S-1 and S-3 by having a larger radiator shutter area (square instead of oblong) and a fat oblong-based stack which goes with the trubocharger. S-2s have Blunt trucks; S-4s have AAR type A trucks.
hi all
I would like very much to know a bit more abouth the Alco S-3 uf the UP
I know from Utahrails website that this switcher was the only one S-3 and was numbered 1250 an unusual number for UP diesel switcher
Utahrails roster of the UP also says that it was painted in UP colours in 1969 and according to the same record it was scraped in 1970 [just a1 year later also very unusual]
My Ho model of the Atlas S-3 shows this locomotive with the UP colours and the slogan SERVES ALL THE WEST wich was obsolete by 1969 being replaced by the new slogan DEPEDABLE TRANPORTATION
Is this Atlas model correct ?
What are the esterior differences [if any ] of the UP Alco S-3 with compared to the other switcher of the UP Alco S-2 and Alco S-4 ?
thanks very much for your help
