Prototype: Pennsylvania Railroad (PRR) class GG-1 heavy general-purpose locomotive. "Loewy" Design in "Tuscan Red", version in the Fifties.
Model: The locomotive comes with an mfx digital decoder, controlled high-efficiency propulsion, and a sound effects generator with many functions. It has a centrally mounted powerful can motor with a bell-shaped armature. 4 axles powered in each power truck. Traction tires. The locomotive has 2 power trucks and 2 pilot trucks and can negotiate sharp curves. The headlights and cab lighting are maintenance-free LED's. The headlights and the cab lighting will work in conventional operation and can be controlled digitally. Large American design pantographs. Length over the couplers 28.0 cm / 11".
A wider wiper for the pantograph may be necessary for operation under catenary mounted in a zigzag pattern or bent to follow a curve. A suitable wiper is available as a spare part: item no. 231802.
The GG-1 is being offered as a Trix model for 2-rail DC using the American standards: item no. 22812 (RP 25).
GG-1: Brunswick Green and Tuscan Red. The Pennsylvania Railroad did not introduce a new form of motive power with the electrification of its main routes in the Thirties; it introduced a new dimension of power for locomotives. The prototype for the GG-1 provided over 4,600 horsepower (3,400 kilowatts) with its 6 twin motors and short term it produced almost 8,000 PS (6,000 kilowatts). With 208 tons on an articulated frame with a 4-6-6-4 wheel arrangement, this locomotive was designed to pull heavy freight trains of up to 6,000 tons and fast passenger trains at speeds up to 145 km/h / 91 mph. Suitably simple adaptations to the gear drive were planned in the design of the locomotive. The French designer Raymond Loewy developed an unmistakable and unsurpassed shape for a locomotive from the prototype, which was similar to a "Crocodile" from the future. The timeless shape goes hand in hand with the indestructible technology for these locomotives, some of which were still in service into the Eighties. Most of the GG-1's were painted in the very dark Brunswick Green. They were designed for general use, and the drive gear could be changed at short notice for freight or passenger service. Several locomotives were used exclusively for the Pennsylvania Railroad's deluxe "Congressional Limited" trains. They consistently kept their high speed gearing and were painted in Tuscan Red, the dignified reddish brown for the entire fleet of the earlier "Pennsy" express train passenger cars. Both versions kept the typical gold colored striping and later broad bands on the GG-1 paint scheme up to the merger creating the Penn Central and the later distribution to Amtrak (passenger trains) and Conrail (freight trains) in the Seventies.
