Traction tires. 2 each 7226 smoke generators can be installed in the locomotive. The headlight changes over with the direction of travel. The headlight, the backup light on the tender, the number board lights, and the smoke unit contacts will work in conventional operation and can be controlled digitally. The engineer's cab lighting can be controlled digitally. Maintenance-free, warm white LEDs are used for the lighting. The locomotive has an articulated frame enabling it to negotiate sharp curves. It also has Boxpok driving wheels. Steam lines are mounted to swing out and back with the cylinders. There is a close coupling between the locomotive and tender. There is a powerful speaker in the tender and the volume can be adjusted. Coupler hooks can be inserted in the pilot on the front of the locomotive.

Additional Information:
- The locomotive can be used on curved track with a radius of 360 mm / 14-3/16" or more, however
Märklin recommends larger radii. Due to the overhang of the long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. must be installed for sufficient clearance on curves. The track must be well mounted due to the heavy weight of the locomotive. The locomotive can only be run through a turntable or transfer table.
