Joined: 28/01/2004(UTC) Posts: 617		Dear Märklin Friends, This oldest version of the 5112 uncoupling track section, has only one wire (black color), which has to be connected to L socket of a Märklin Trafo for uncoupling. Does somebody know, please, how (i mean with what) it was correctly managed in a Layout in the early '50?. Thank you very much for any advice! Best regards Stefano Rocca

When the switch is closed (E.g. with a push button) then the current will flow through the wire, through the coil (and thus actuate the uncoupler) and then to the ground of the track.

I only thought it was existing, maybe, a special switcher of those ages, that would make it possible, without overloading the uncoupling switch. Thank you so so much for the advice!

At the same time transformers were delivering 16 V for lamps and 20 V for solenoids. So the black wire goes to the 20 VAC. Cat Marklin 1950 FR.pdf (5,034kb) downloaded 17 time(s). Look especially at pages 18 and 19 (transformer outputs): Red for track 7 to 12 VAC), Yellow for lights (16 VAC) and Green for Solenoïds (20VAC) Operation by "Stellpults" Control boxes 474/4 (4 buttons) or 474/8B (8 buttons with back lighting) See page 35. Cheers Jean
