This model has never been run and only has been removed from packaging for sale photos. NOTE: Front and Rear handrails as well as the snow plow are packaged separately (see photos).Information from Atlas web site: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.

There were three distinct “phases” of GE 4-axle “Dash 7” locomotive production. Our models on this run represent \"Phase 2\" units with a 37\' 2\" wheel base. Phase 2 production lasted from the Spring of 1979 through the Fall of 1980.
