Roller-type test stand for model railway locomotives has base rail, bearings and roller brackets formed form three metal profile sections stuck together via insulating material

摘要

The test stand has a base rail, and a variable number of roller bearings brackets for driven axles, a short bearing bracket, and a long bearing bracket for non-driven axles. The base rail, bearing and roller brackets consist of three metal profile sections stuck together, with insulating material between the sections, so that they form electrically isolated components for supply of current to the locomotive.
