Model: All cars have factory-installed indirect LED interior lighting, which can be dimmed and controlled digitally using a decoder in the control car. There are buffer capacitors to bridge short spots without current. The control car is fitted with an mfx digital decoder. The triple headlights and dual red marker lights will work in conventional operation and can be controlled digitally. Long-distance headlights, cab lighting, and control desk lighting in the control car can be controlled separately in digital operation. There are 4-pole current-conducting couplers fitted between the express train passenger cars. The express train passenger car with running number 1 is fitted with a 2-pole coupler in an NEM pocket as an electrical connection to the locomotive. Maintenance-free warm-white and red LEDs are used for the lighting. Car 1 is aligned with the locomotive with a rubber gangway connection. The interior details are modeled in detail in multiple colors. The minimum radius for operation is 360 mm / 14-3/16", ignoring the clearance gauge. For operation on larger radii, the skirt fitted as standard in the area of the couplings at the ends of the cars can be replaced with a separately supplied skirt. A defined car sequence is specified to enable the full functionality of the entire train. Length over the buffers approximately 214 cm / 84-1/4". The matching class 101 electric locomotive is also available in the Märklin H0 range as item 39478. In keeping with the prototype, only the class 101 electric loco, item 39478, can be coupled with the express train passenger car set, item 42930. This item has been developed in a cooperative venture with PIKO Spielwaren GmbH, Sonneberg, Germany. Find more Märklin explanation videos on our YouTube Channel.
