Atlas - HO Scale - Gold Series - B23-7 BNSF #4230 (Green/Orange/Yellow) - Sound & DCC Installed (SKU 1500-8145)

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. The first units were produced for Conrail in September, 1977 (ironically, 3 months after the last U23B was delivered to Conrail). 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.
Several features distinguished B23-7s 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 on B23-7s, but some railroads opted to use ?trade-in? trucks. Therefore, AAR type B and Blomberg trucks could be found on some models. The 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..
There were three distinct ?phases? to B23-7 production. Our model is of a ?phase 1? unit with a 36?2? wheel base. Phase 1 production lasted through the spring of 1979..
