The Baldwin Class 12-48 ¼ E was a class of 2-8-2 "Mikado" type steam locomotives that were built by the Baldwin Locomotive Works for several railroads all across the United States of America.
History.
The Baldwin 12-48 ¼ E locomotives were constructed between 1911 and 1917, not only built by the Baldwin Locomotive Works (BLW), but were also built in a collaboration between the American Locomotive Company (ALCO) at their own Richmond, Virginia works, and the Lima Locomotive Works (LLW).
Two railroads, used this locomotive design. The Southern Railway (SOU) owned 182 of these locomotives and classified them as their Ms class.
The Mobile and Ohio Railroad (M&O) purchased 21 engines and they classified them as the class 400. The Denver and Rio Grande Railroad (D&RG) purchased 13 similar locomotives in December 1912 which they classified at first as their 280 class, these later became their K-59 class when the D&RG merged with the Rio Grande Western Railroad (RGW) to become the Denver and Rio Grande Western Railroad (D&RGW).
The Wabash Railroad Company (WAB) also used some 2-8-2s similar to these and classified them as their K-1s.
