This rolling road can be used to run in new locomotives, or to test issues and repairs. 

This newly developed and patented rolling test bench consists of three rolling blocks for one axle each (not all axles of a locomotive have to be underlaid with rolling blocks). Two contact surfaces serve as a track support per roller block and transmit the power from the track via the rollers to the wheels of the locomotive. The roller blocks can be extended by additional contact springs (included) with an additional centre conductor contact for the Märklin® system. The castors are precision turned parts to ensure optimum running properties and power transmission.
