Stan Rothwell has kindly contributed this 'potted' history of the SP RSD12's, thanks Stan, more contributions like this welcomed.
These units are interesting in that they were carried as "rebuilds" on the SP books. In 1961 SP sent 21 RSD-5s (SP #5294 - 5307, 5336 - 5339, 5445 - 5447) back to Schenectady for rebuilding. A new 251 prime mover was used; trucks and generators were reused. I'm not sure if new frames were fabricated, but they were all were low nose.
In 1965 these units were reclassified as switchers and renumbered 2950-2970.
Quite a few of these wound up in the Los Angeles area in the 1970's, and were quite common on the Taylor-West Colton transfer drags, along with the double-engined units and whatever else SP could scrape up for the occasion. One of the more interesting consists I saw in 1977 consisted of an SD45, an SW1500, an Alco C415, an RSD12, a U50 AND a DD35B (as well as a couple other EMD's which I don't remember)!
A few of these units were stored in the Bullring Yard (old SP passenger yard N of Chinatown) by 1980, and later moved to Aurant Yard in Alhambra (5-6 miles east of downtown LA) where they were heavily vandalized. They didn't actually leave SP property until 1986 when SP did some housecleaning.
Two of these units wound up in Long Beach at Metropolitan Stevedore, and were recently donated to the Orange Empire Railway Museum in Perris. They are currently on BNSF property awaiting rail shipment to Perris once certain brake repairs have been completed to satisfy FRA requirements.
Latest on the units above, from Stan Rothwell is that they are now at Perris. Present status is that the units run 'somewhat', but require some further brake work and have more than their share of flat wheels.
Late News: The numbers of the Metropolitan Stevedore units at Perris are 2954 and 2958.
Chapter xx of the Joe Strapac listed below provides further information on the RSD12's. These were RSD5's with the flawed Alco 244 engine, Alco agreed to do a frame up rebuild with 251 engines. They received carbodies similar to the then current RS11.
