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. 4 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. The long-distance headlights, the cab lighting, and the electric locomotive operating sounds, as well as the acceleration and braking delay can be controlled with a 6021 Control Unit or Märklin Systems. Additional operating sounds can be controlled with Märklin Systems: bell, horn, the pantograph mechanism, and blower motors. Additional sounds can be controlled with the Central Station: the sounds of the relay system at work, cab radio "chatter", the sounds of couplers engaging, and the "clickety-clack" sound of the train running on jointed rail and the sound of squealing brakes. Large American design pantographs. Length over the couplers 28.0 cm / 11". Highlights: Locomotive constructed of metal. Controlled high-efficiency propulsion with a powerful can motor with a bell-shaped armature. mfx decoder with many operating, light, and sound effects functions. Electric locomotive sounds as in the American prototype. 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.
