The U23B was General Electric’s competitor to the EMD GP38. The little U-boat has a 12-cylinder FDL engine, necessitating six tall engine access doors on each side. Buyers included Santa Fe, Conrail, Delaware & Hudson, Lehigh Valley, Milwaukee Road (pictured), Monon, Penn Central, Western Pacific, and others. Most rode on AAR type B trucks, but some, like MILW 4802, were equipped with GE’s distinctive FB-2 trucks.
