Model: This is a 5-part basic set. The dining car G and the two intermediate cars F and H arranged on the left and right are coupled permanently with Jakobs trucks. The train has an mfx+ digital decoder and extensive sound and light functions. It also has controlled, high-efficiency propulsion with a flywheel, centrally mounted in the dining car. All 4 axles in both Jakobs trucks on the left and right of the dining car are powered using cardan shafts. Traction tires. The cabs in the end cars have interior details. Current pickup is done from the end car at the front of the train and changes with the direction of travel. There is a guide mechanism in the Jakobs trucks. Triple headlights and dual red marker lights change over with the direction of travel, will work in conventional operation, and can be controlled digitally. The train can be switched to a white marker light (Swiss headlight / marker light code). There are additional separately controlled light functions. The train has factory-installed interior lighting. The interior lighting is supplied with power from a continuous electrical connection throughout the entire train. The cab and control desk lighting are also each controlled separately in digital operation. Maintenance-free warm white and red LEDs are used for all of the lighting. The pantographs on the F and H intermediate cars can each be raised and lowered separately as a digital function. The train is modelled true-to-scale. The minimum radius for operation is 360 mm / 14-3/16". Length of the basic set approximately 112 cm / 44-1/8". The 39812 5-part basic set can be expanded to a prototypical 11-part powered rail car train with the 43451, 43452, and 43453 2-part add-on car sets.
