Prototype: Three different design German Federal Railroad (DB) express train passenger cars for the "Rheinpfeil" express train F22 from Dortmund to Munich. One type AD4üm-62 vista dome car, 1st class, with a raised panorama compartment and service areas beneath it. The vista dome area has four side windows. One type Av4üm-62 compartment car, 1st class, and one type Ap4üm-62 open seating car, 1st class. Cobalt blue / beige basic paint scheme. The cars look as they did in the summer of 1963.

Highlights:
- newly designed interior lighting for the vista dome car to light up the dome area better;
- all of the cars include built-in LED interior lighting;
- one car includes built-in marker lights;
- operating, current-conducting couplers.

Model: All of the cars have factory-installed LED interior lighting with warm white LEDs. The open seating car has factory-installed marker lights. All of the cars come from the factory with current-conducting close couplers. The interior lighting and the marker lights work only in conjunction with the humped back dining car from the 43882 set and they 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 85 cm / 33-7/16".

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 43882.
