The Atlas Gold 40005459 N Scale model of the GE B23 - 7 ATSF Santa Fe #6400 features a Warbonnet paint scheme in blue and yellow. Note that 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 directly replaced the 2,250HP U23B. Production ran from 1977 to 1984, with 535 units built, and Conrail was the biggest buyer with 141 units. The B23 - 7 has unique features. Its long hood steps out by the exhaust stack for an oil cooler, and the frame is 2 feet longer than the U23B. It usually has an FB - 2 style truck, but some models may have AAR type B or Blomberg trucks. The six power assembly doors near the long - hood center show it's powered by a 12 - cylinder GE FDL engine. Key features include directional lighting with golden - white LEDs, dual brass flywheels, a low - friction mechanism, accurate painting and lettering, and factory - installed AccuMate® magnetic knuckle couplers. Gold locomotives offer great DCC operation features, supporting all DCC - programming modes, including RailCom and RailComPlus with various speed steps and addressing options.
