ALCO Boxcab

The ALCO boxcabs, also known as AGEIR boxcabs, were early diesel electric switcher locomotives built between 1925 and 1928 by a partnership of three companies: the American Locomotive Company built the chassis and running gear, General Electric supplied the generator, motors and controls, and Ingersoll Rand built the diesel engine, which drove a 600 volt DC generator powering four traction motors. Thirty three units were produced across three models rated at 60, 66 and 100 tons, and after Ingersoll Rand and General Electric acquired their own diesel engine maker, the American Locomotive Company built further boxcab and end cab switchers in 1931 using engines from that source before developing its own HH series. Five of the earliest boxcabs survive today in railway museums in Baltimore, St Louis, Huntsville, Union, Illinois and Dearborn.
