Prototype: Two different design German Federal Railroad (DB) express train passenger cars for the "Rheinpfeil" express train F22 from Dortmund to Munich. One type WR4üm-62 dining car with two dining areas, a galley, a washing up area, a buffet, and a crew compartment. One type Av4üm-62 compartment car, 1st class. Cobalt blue / beige basic paint scheme. The cars look as they did in the summer of 1963.

Highlights:
- extensive light and sound functions with a built-in decoder in the dining car;
- dining car includes table lamps that can be controlled separately;
- all of the cars include built-in LED interior lighting;
- the upper and lower galley lighting can be controlled separately.

Model: The dining car has an mfx digital decoder and extensive light and sound functions. The table lamps, area lighting, vestibule lighting, and bar lighting can each be controlled separately. Both cars have factory-installed LED interior lighting with warm white LEDs. Both of the cars have current-conducting close couplers. The interior lighting works only in conjunction with the dining car and it can be turned on and off digitally using a decoder. The specified sequence of cars must be maintained for this purpose. The roof shapes, side walls, underbodies, and skirting are specific to the car types. The trucks are type Minden-Deutz with brake shoes, magnet rail brakes, and separately applied generators. The train destination signs are imprinted on the cars. The minimum radius for operation is 360 mm / 14-3/16". Total length over the buffers approximately 57 cm / 22-7/16".

Motive power and an add-on express train passenger car set to go with this car set can be found in the Märklin H0 assortment under item numbers 39126 and 43881.
