Owner's Manual
The ALCO DL-109 was one of six models of A1A-A1A Diesel locomotives built to haul passenger
trains by the American Locomotive Company (ALCO) between December, 1939 and April, 1945
(“DL” stands for Diesel Locomotive). They were of a cab unit design, and both cab-equipped lead
A units DL-103b, DL-105, DL-107, DL-109 and cabless booster B units DL-108, DL-110 models
were built. The units were styled by noted industrial designer Otto Kuhler, who incorporated into
his characteristic cab (US Patent D121,219) the trademark three-piece windshield design. A total
of 74 cab units and four cabless booster units were built.
