The picture might show a different road number. General Electric's 'Dash 7' locomotive line replaced the older 'Universal - Series' from the 60s and early 70s. It offered better fuel efficiency, tractive effort, and reliability. The B23 - 7 replaced the 2,250HP U23B model. Production started in September 1977 for Conrail and lasted until 1984, with 535 units built. Conrail bought the most, with 141 units. The B23 - 7 has some unique features. Its long hood steps out at the exhaust stack for a relocated oil cooler, and the frame is 2 feet longer than the U23B. It usually has an FB - 2 style truck, but some models have AAR type B or Blomberg trucks. The six power assembly doors near the long - hood center mean it's powered by a 12 - cylinder GE FDL engine.
