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.\u003c\/p\u003e","brand":"Atlas Model Railroad Company","offers":[{"title":"Default Title","offer_id":50060557451510,"sku":"AHO-10004700","price":163.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/0560\/files\/h10004699_0c8c7826-3447-4ad0-aac7-06fe6cda907a.jpg?v=1772384317","url":"https:\/\/mrmuffinstrains.com\/products\/aho-10004700","provider":"MrMuffin'sTrains","version":"1.0","type":"link"}
