Are you a garden railroader and would like to switch blades on your garden railway as slow as real tracks do? With the EVO-S, Massoth has not only improved the switch drive, but practically reinvented it and filed a patent application for the unique product concept. What makes it so unique? It offers the typical slow drive, and at the same time the possibility to push open the switch blades from the frog. The EVO-S is the only drive that can switch the drive back to the previous position after opening the blades. Alternately, the drive can be configured in such a way that the switch blades fit closely against the tracks.
