The GP40-2 was EMD’s follow-up to the very successful GP40 locomotive model. While many internal upgrades were introduced (such as the use of improved, modular Dash 2 electrical components), there were some external differences between the early production GP40-2 and late-production GP40. This included an engine water-level sight glass on the right side of the body (a feature common to all EMD Dash 2 models), a larger electrical cabinet air filter box, a lengthened battery compartment on the left side, and a slightly modified cab.

All GP40-2s featured a 16-cylinder EMD 645-series diesel engine which was rated at 3,000 horsepower. Early to mid-production phase 2 GP40-2s were built from mid-1976 through late-1979. Several major spotting features of Phase 2 units include: an 88” low nose, corrugated radiator grilles and notched step wells.

• Dynamic Brake options: standard range, extended range or non-dynamic brake hatch used where appropriate per road name.
• 3,600 gallon fuel tank.

Undecorated units information:

• Dynamic Brake Part: standard range and non-dynamic brake hatch
• Hood and frame bells included
• 3,600 and 2,600 Gallon fuel tanks included
• Trucks: Blomberg Type-M only

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

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.
• 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 GP40-2 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 GP40-2) 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.)

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.
