Atlas Master Line HO 10003806 Gold Series U33/36B Locomotive, CSX (MCVX Safety Train) #7764





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.

Analog (DC) Operation Features:
The LokSound Select Dual-Mode decoder allows your Atlas Gold Series locomotive to be used on DC as well as on DCC layouts.

DCC Operation Features:
Supports all DCC-programming modes – Flexible mapping of function keys F0 to F28.
A total of six DCC function outputs are available
Follows all NMRA DCC standards and recommended practices.

Sound Functionality Features:
Over 20 sound effects are available, including engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes and more.
There are 16 user-selectable horns, 2 user-selectable bells, and 2 user-selectable synchronized brake squeals.
Manual and Automatic Notching modes with the ability to change modes “on the fly” are provided for true realism.

Please note that the Atlas Quantum Engineer will NOT operate an Atlas Gold Series locomotive equipped with a LokSound Select decoder on an analog (DC) layout. However, the sound and lighting functions of the LokSound Select decoder in the Atlas Gold Series U33/36B locomotive can be controlled by an easy-to-use basic DCC system

Also note that on a DC-powered layout, a DCC and sound equipped locomotive (such as the Atlas Gold Series U33/36B) CANNOT be consisted with another locomotive that does not also have both DCC and sound. (This statement does NOT apply to DCC-equipped locomotives operating on a DCC layout.)
