stlsw 4-8-4 "Northern" Locomotives in the USA

The St. Louis Southwestern Railroad acquired Northerns at three different times. It bought 10 Class L-1 Northerns in 1930 from the Baldwin Locomotive Works and assigned them road numbers 800 through 809. These 4-8-4s were oil burners with 70" drivers, 26 x 30 cylinders, a boiler pressure of 250 psi, a weight of 419,800 lbs and a tractive effort of 61,564 pounds.

In 1937, StL-SW's Pine Bluff, AR shops built five (road numbers 810 through 814) additional Class L-1s which were identical to the 10 from Baldwin. Then, in 1943, another five (road numbers 815 through 819) came out of the Pine Bluff shops which were very similar to the other Class L-1s except they weighed about 6,000 pounds more.

There is one surviving Class L-1, number 819, at the Arkansas Railroad Museum in Pine Bluff, AR.
