This is for servicing and presenting locomotives with up to 8 driving axles and coupled axles. This roller test stand is suitable for the "Big Boy". Eight adjustable pairs of roller brackets with precision ball bearings are included. The aluminum parts of the roller brackets are black anodized. The construction and technical features are the same as the 78150 roller test stand.
The test stand has train power connections for a conventional transformer or a Digital system. The roller test stand has a removable center conductor in the roller area. The running rails can be connected separately to a power pack, thus making this test stand suitable for two-rail locomotives.
