Atlas' Store: H0 MASTER EMD GP40 LOCOMOTIVE

Atlas tells us about the GP40:

    In 1966 EMD introduced a new line of locomotives based on the 16-cylinder 645-series prime mover. The “40-series” included a six-axle and four-axle model, the latter being the GP40. A total of 1,145 units were produced between 1966 and 1972. These turbocharged 3,000hp locomotives were used primarily in road freight service. The GP40 was a versatile locomotive that could be found across the US hauling drag freights over mountain passes and leading high-speed intermodal trains across flat terrain. Three rooftop radiator fans at the rear of the long hood differentiate a GP40 from its lower horsepower counterpart, the GP38, which has two fans at this location.

    Concurrent with GP40 production, EMD offered a lower horsepower, non-turbocharged locomotive based on the same 645-series prime mover. The four-axle GP38 was rated at 2,000 hp and had the advantage of costing less than the GP40. A total of 727 units were produced between 1966 and 1971 when the model was superseded. The wheelbase of the GP38 was identical to that of the GP40. Both units shared the same EMD road-switcher style body that was introduced with the GP35 in 1963. A desire for standardization caused the GP38 to share the same wheelbase, frame and many external components as the GP40. The GP38 was purchased by large and small roads alike. It was routinely found in local and road freight service throughout the US. Many GP38s and 40s are still in service today.

Master™ Series Silver GP40

Atlas packages this model in a telescoping lid-tray carton.  The lid has a clear sheet viewing window to display the model.  Inside, the model is secured in a three-piece plastic cradle which is very secure; the third piece is a hard plastic base to which the locomotive is affixed by two screws. A foam block protects the top of the body. Thus it can not shift about and scuff. It is also unlikely to topple out of the cradle if one handles it clumsily. (Don't ask how I know.) The screws hold the loco where the fuel tank is located.

 A small bag of optional parts is included.

 An exploded-diagram line art parts sheet is included. It shows all parts and components, most with its part number. However, while well detailed, it provides no guidance as to how to attach or detach anything.

The box window allows for a good first impression. Immediately noticed a sharply molded and detailed model. The styrene shell is sharply molded and detailed with molded-on/in hood access doors with hinge and latch detailing, a radiator cooling vent, rivet detail and such.

The model is engineered with plastic frames on metal truck sand wheels, a cast metal chassis frame for weight, an injection-molded body shell and a sill, detailed with plastic and metal parts. It is further equipped with AccuMate® knuckle couplers. Inside the body is the motor, dual flywheel drive shafts and electrical suite.

Atlas short and long body shells are modular for railroad-specific details. The shell has a cutout for the dynamic brake hatch, of which there are three types. These snap into place, as does the single-piece cab. Three different plows and two sizes of fuel tanks are available. Other details specific for individual railway companies are ditch lights and headlight configurations.

Detail

Options for the Atlas GP38 and GP40 models include a long hood with or without dynamic brakes and an underframe with 2,600 or 3,600 gallon fuel tanks.   As listed above, Atlas equips their GP40 with plentiful individually-applied details:

    ·        Detailed cab interior with crew

    ·        Separately-installed scale windshield wipers, metal grab irons and fine scale handrails

    ·        Movable drop steps

    ·        Walkway safety tread

    ·        Coupler cut bars

    ·        Multiple unit hoses and trainline hoses

    ·        Snowplow

    ·        Lift rings on the body roof

    ·        Windshield wipers

    ·        Clear eye glass on right hood

    ·        Piping on the trucks

Additional feature parts included but not installed(GP-40):

    •              Electrical cabinet air filter box (ECAFB)

    •             Two engine compartment roof vents which were added by many railroads sometime after delivery

The  locomotive body hosts more than 60 individually-applied detail pieces!  The cab interior contains an interior wall, control stand, an engineer, a fireman, and seats.   Notice the etched fans inside the roof grilles?  Detailed truck sideframes sport separately applied brake cylinder with piping and spring hangers.  The AccuMate couplers are mounted to the frame instead of the trucks. The cab is shielded from headlight and number board illumination.

Separate sun shades and two round parts are held in the baggie.

When one looks closely at this model, "wow" should come to mind.

Technical

EMD GP40s are 59 feet 2 inches long.  This model is 59 feet 9 inches from couple to coupler.  This model weighs 13.8 ounces.  I did not check the drawbar pull the loco should allow you to pull 35 cars weighted to NMRA standards along flat tangent track.

Throttle Up! 

This model is ready to go straight out of the box.

With the weight of the die-cast frame this loco can pull a respectable consist. The can motor and flywheel assembly, transmission linkage and gearing gives a smooth performance.

Let the Light Shine

This model is equipped with golden-white LEDs for illumination. Headlights, number boards,and cab lights illuminate.  The lighting is directional.

Paint and Markings

The first quality of this model that I noticed is the smooth, sharp, painting and markings. There are several stencils on the unit.  All are legible, even those smaller than my camera’s resolution can display. You can see those markings in the photos.

Atlas provides more than one road number for a given railroad.  Other road names for this release include:

    Bangor and Aroostook (Blue/Yellow)

    Conrail "White Frame Stripe" (Blue/White)

    Conrail "Bicentennial" (Red/White/Blue)

    Norfolk Southern (Black/White)

    RJ Corman (Red/Silver/White)

    New Orleans Public Belt (Orange/Black)

    Georgia Railroad* (Black/White)

    Western Pacific "WP Nose Lettering" (Green/Orange)

    B&O* (Blue/Yellow)

    Southern Pacific "Speed Lettering" (Scarlet/Gray)

    NJ TRANSIT (Silver/Black/White)

Each road name comes with two or three road numbers.

Summary

Atlas' Master™ Series Silver GP40 is an impressive model! The fidelity and amount of detailing, ease and smoothness of operation, molding, engineering and quality all combine to make this an exceptional model.   So does the paint and markings.   The number of railroads available means few modelers will not have the choice of a GP40 for their layout.

 Model railroaders modeling the past 50 years have a great deal of choice with this impressive GP40.   Recommend.
