General Electric’s “Dash 7”
locomotive line was introduced as a replacement for the older “Universal-Series”
of the 60s and early 70s. “Dash 7” series improvements included
increased fuel efficiency, tractive effort and reliability. The B23-7
was a direct replacement for the 2,250HP U23B model, while the B30-7 replaced
the 3,000HP U30B. The first B23-7s were produced for Conrail in September,
1977, and the first B30-7s were produced for Frisco three months later.
B23-7 production continued through 1984, with a total of 535 units
built. Conrail was the largest purchaser of the model, with a total
fleet of 141 units. 199 B30-7s were produced through 1981, with the
combined fleets of Southern Pacific and Cotton Belt being the largest
at 110 units.
Several features distinguished B23-7s and B30-7s from predecessor models.
The long hood stepped outward in the area of the exhaust stack to accommodate
a relocated oil cooler. In addition, the frame was 2 feet longer than
that of the U23B. An FB-2 style truck was offered as standard equipment,
but some railroads opted to use “trade-in” trucks. Therefore,
AAR type B and Blomberg trucks could be found on some models. Six power
assembly doors (located near the center of the long hood) indicated
that the B23-7 was powered by a 12-cylinder GE FDL engine. Eight power
assembly doors in the same location help to identify the B30-7, which
included a 16-cylinder FDL engine.
