Santa Fe RS1 2394
at San Bernardino, CA in 3/73. The RS1 can be distinguished from Alco
switchers by the presence of a short hood and road trucks, while they can
be distinguished from RS2's and RS3's by the square-edged cab and the switcher
style long hood.
Pacific Fruit Express S3
1023 at the PFE repair facility at Roseville, CA in 7/72. This S3 was
ex-SP, and was used to shuttle reefers needing repair into the shop. S3's
can be distinguished from other Alco switchers by the narrow radiator (taller
than it is wide) and AAR Type A trucks (the same as used by EMD). S1's
have Blunt trucks but are otherwise identical.
Sacramento Northern S2 406
at an onion dehydrating plant (smelled like hamburgers!) at Vacaville, CA
in 9/71. The S2 can be distinguished from other Alco switchers by the
wide radiator (wider than it is tall) and Blunt trucks (different from any
other truck design). The S4's have AAR Type A trucks but are otherwise
identical.
Soo Line RS1 352 at the North
Fon du Lac, WI shops on 7/20/73. Note the switcher style cab and long
hood, but also the short hood and road trucks that distinguish the RS1.
