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.\u003cbr\u003e\u003cbr\u003eSeveral 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.\u003cbr\u003e\u003cbr\u003eThere were three distinct \"phases\" of GE 4-axle \"Dash 7\" locomotive production. Models on this run represent both \"phase 1\" and \"phase 2\" units. Phase 1 units feature a 36 ’2\" wheel base and were built through the Spring of 1979. Phase 2 units feature a 37' 2\" wheel base, and production lasted from the Spring of 1979 through the Fall of 1980.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e\u003cbr\u003eThe Atlas B23-7 and B30-7 locomotive models include such optional\/road name specific details as:\u003cbr\u003ePilots with and without anti-climber\u003cbr\u003eCab headlights or low-nose headlights\u003cbr\u003eCab with 4 or 2 side windows\u003cbr\u003eBell mounted under the sill or on the long hood\u003cbr\u003eFB-2, AAR type B, or Blomberg truck side-frames used where appropriate per road name\u003cbr\u003e\u003cbr\u003eAdditional Features:\u003cbr\u003eSeparately-applied scale detail parts include: windshield wipers, metal grab irons, coupler cut levers, multiple-unit hoses, snow plow, train line hoses, fine scale handrails, and more!\u003cbr\u003eSee through step detail on sill\u003cbr\u003eEtched metal radiator grilles\u003cbr\u003ePainted crew members\u003cbr\u003eFactory-equipped with AccuMate knuckle couplers\u003cbr\u003eCoupler pocket designed to accept AccuMate Proto-couplers\u003cbr\u003eFive-pole skewed armature motor with dual flywheels for optimum performance at all speeds\u003cbr\u003eDirectional lighting\u003cbr\u003e\u003cbr\u003eAtlas Master Series Gold Additional Features:\u003cbr\u003eSound equipped","brand":"Atlas","offers":[{"title":"Default Title","offer_id":43565460881471,"sku":"ATL-10004723","price":283.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0269\/7461\/7663\/files\/h10004707__21608_0373a5fe-501b-4eb3-a419-0422f1db2584.jpg?v=1784678646","url":"https:\/\/factorydirecthobbies.com\/products\/in-stock-atlas-master-line-ho-10004723-gold-series-ge-b30-7-low-nose-southern-pacific-7828-dcc-sound-equipped-283-46","provider":"Factory Direct Hobbies","version":"1.0","type":"link"}
