The roll test stand is used to jack up a locomotive. With the roll test stand current transfers from the rail to the wheels of the locomotive allowing them to turn freely while the locomotive remains stationary. The roll test stand is handy in the workshop for locomotive repairs, cleaning, oiling, or for displaying locomotives on bookshelves, etc.
This newly developed and patented roll test stand consists of three sets of roller supports each of which cradles an axle (all the axles of a locomotive do not have to be supported with roller supports). Two contact areas pick up current from the track and pass it to the wheels through the roller support casters. The roll supports can be made compatible with the Märklin® system by the use of additional contact springs (to be provided) and an additional neutral conductor contact. The roller supports are constructed of high-precision turned parts, which ensure smooth running properties and current transmission.
