fell to the scrappers torch under the Penn Central at Dover Street Yard in Boston, in August 1970. The DL-109s of the other railroads were primarily scrapped during the 1950s. The Rock Island had rival builder EMD repower their newest, the #621, with dual V12 567B engines but this does not seem to have extended its career greatly. The Chicago and North Western retired its DL-107 in 1954 after it developed a cracked frame after a derailment on a turntable. The units on the Milwaukee logged over 3 million miles by 1953, and were overhauled. The electric motors and prime movers were sent to Alco for rebuilding, and the shopmen at the Milwaukee Road's Menomonee Valley shops rebuilt the locomotives. They came out of the shops with facelifts, with the addition of EMD bulldog noses, and changed appearance, which made them look like an EMD locomotive. The units then worked on secondary lines to Canton, South Dakota, Green Bay, Wisconsin, and Madison-Chicago trains until retirement; #14B was finally scrapped at Jones Island in Milwaukee in May 1964. None have been preserved. Units produced A units (cabs) B units (cabless boosters) References (1972). "DL109/110 Roster and Drawings." Extra 2200 South 9 (8) by Dan Dover and W. A.
