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 (BLW) 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).^{[citation needed]}

Two railroads, used this locomotive design. The Southern Railway (SOU) owned 182 of these locomotives and classified them as their Ms class.^[1]^[2]

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).^{[citation needed]}

The Wabash Railroad Company (WAB) also used some 2-8-2s similar to these and classified them as their K-1s.^{[citation needed]}

Preservation

Only one locomotive was preserved:

Southern 4501, built in October 1911 is currently operational at the Tennessee Valley Railroad Museum based in Chattanooga, Tennessee.^[3]
