Prototype: German Federal Railroad (DB) class VT 92.5 four-axle diesel-powered rail car. Buffer cladding included. Based in Nürnberg. In limited stop fast train service on the routes Nürnberg-Amberg and Nürnberg-Furth im Wald as an experimental combustion engine rail car among other things. Crimson basic paint scheme. Powered rail car road number VT 92 501. The car looks as it did around 1957 to 1959.

Highlights:
- completely new tooling;
- first time as a Märklin H0 model;
- the frame and body of this diesel-powered rail car are constructed mostly of metal;
- ventilation propeller fan mechanism can be controlled in digital operation;
- cab lighting, baggage area lighting, corridor lighting, restroom lighting, sleeping compartment lighting, and locker room lighting can be controlled in digital operation;
- current-conducting close couplers are included at both ends.

Model: The unit has an mfx+ digital decoder and extensive sound and light functions. It also has controlled high-efficiency propulsion with a flywheel. Two axles in the motor truck are powered using a cardan shaft. Traction tires. Dual headlights and dual red marker lights change over with the direction of travel, will work in conventional operation, and can be controlled digitally. The headlights and marker lights front and rear can be controlled separately in digital operation. Cab lighting front and rear can also be controlled separately in digital operation. In addition, baggage area lighting, corridor lighting, restroom lighting, sleeping compartment lighting, and locker room lighting can be controlled separately in digital operation. Maintenance-free, warm white and red LEDs are used for the lighting. A working ventilation propeller fan is included. The ventilation propeller fan mechanism can be controlled separately in digital operation. Current-conducting close couplers are included at both ends. Interior lighting for passenger cars from the 41327 limited stop fast train car set coupled to this unit can be controlled separately in digital operation using the current-conducting close coupler on the powered rail car. End skirting is included and can be installed for a version of the powered rail car without plugged in close couplers. The powered rail car has detailed buffer beams. Brake hoses, imitation prototype couplers, and heating lines, which can be installed on the unit, are included. In addition, the buffer cladding installed on this unit, which is necessary for reliable operation with cars coupled to it, can be swapped with buffer cladding of prototypical height.

The class VT 92.5 diesel-powered rail car is being produced in 2021 in a one-time series only for Insider members.
