Model: The rail bus has an mfx decoder and extensive sound functions. It also has controlled high-efficiency propulsion with a flywheel in the motor car. 2 axles powered. Traction tires. The rail bus has factory-installed interior lighting in the motor car and the trailer car. The rail bus has dual headlights and dual red marker lights that change over with the direction of travel, will work in conventional operation, and can be controlled digitally. The headlights at the Engineer‘s Stand 2 and 1 of the motor car can be turned off separately. Dual red marker lights are on for the trailer car depending on the position of the motor car. Maintenance-free warm white and red LEDs are used for the headlights, marker lights, and interior lighting, and they can be controlled together in digital operation. The rail bus units have a current-conducting drawbar coupling with a guide mechanism between them. An additional non-current-conducting drawbar coupling is included for use in multiple hookups of rail bus sets. When you have a maximum 4-part unit (2 double units), the red marker lights on the trailer car can be turned off by means of a switch. The engineer‘s stands and the cars‘ interiors in the motor car and trailer car allow an open view through the windows. Brake hoses are included and can be mounted on the rail buses. Length of the two-unit set approximately 28.2 cm / 11-1/8“.
