BALDWIN DS-4-4-1000 DIESEL-ELECTRIC LOCOMOTIVE
The Baldwin DS-4-4-1000 were two models of four-axle 1,000 horsepower (746 kW) diesel-electric switcher locomotives built by the Baldwin Locomotive Works between 1946 and 1951. The first models (56 locomotives) were powered by an 8-cylinder normally aspirated prime mover, but from 1948, a change was made to the second model powered by a 6-cylinder turbocharged engine. These two models replaced the VO-1000 in Baldwin's catalogue, and were in turn replaced by the S-12 in 1951.

Southern Pacific Baldwin DS4-4-1000 No. 1393 in a builder photo at Eddystone, Pennsylvania, August, 1948.
As per Rich Sievers, the "DS 4-4-1000s predated the S12s and followed the VO 1000s (SP bought all three models), and referred to their DS 4-4-1000s as 'S-10s'."
SP 1393 was the first unit of an order for ten units built in August and September, 1948. It was renumbered SP 1863 in the 1965 general renumbering.
It was retired on May 18, 1972, and traded in to EMD in September, 1972.
