Viessmann HO 5235 Decoder for C-Track, 3-way. Same as item 5231, single track decoder but for a Märklin C-track, three-way turnout. Controls 2 drives. Decoder can be controlled by loc addresses and can thus be used for driving devices unable to address switching decoders (such as the early Mobile Station and Roco Lokmäuse). Suitable for Märklin-Motorola, NMRA-DCC and Märklin systems. Electronics are still sealed in plastic.
