Introduction

Atlas Gold 40005468 N Scale GE B30-7 Chessie System C&O 8243 DCC LokSound

General Electrics 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.
