Atlas Master Line HO 10003789 Silver Series U33/36B Locomotive, Auto Train #4009

Silver Series – DC Standard

The horsepower race was in full swing by the late 1960s when GE introduced the 3,300hp, four-axle U33B locomotive. 137 units were produced between September 1967 and August 1970 when production ended. GE upped the horsepower ante in 1970 with the introduction of the 3,600hp U36B which was produced between May 1970 and December 1974. Both models were externally identical, and internally they were both powered by the same GE FDL-16 cylinder four-stroke engine. The horsepower increase was achieved through adjustments to the fuel rack settings and other internal component changes. One key spotting feature of both models was the built-out radiator “wings” on the long hood.

Atlas’ U33B and U36B model is being offered in both an early and late phase. The early phase model includes flushmounted radiator screens and air intake screens on the long hood. In addition, there is a built-out area on the top of the front and rear pilots. Late phase models include corrugated radiator and air intake screens, with a flat pilot face. An optional separate electrical equipment box is included on the left side walkway behind the cab per the prototype. AAR-B or Blomberg trucks are used when appropriate.
