In order not to destroy my landscape, i cannot solder the feedback wire below the track... So, i am creating small section (shorter than a piece of track in order to have not connected rails) by cutting one rail in the middle of a track piece. My problem is to solder on the rail. It seems that the metal used for Marklin C-track is difficult to solder... Does anyone knows about this ? Any solutions ? Thank you in advance, Francois.

NN Phosphoric Fluxes are a bad choice for any electronics work since they're so corrosive. I've used superior no515 for stainless soldering with decent success. It still needs thorough cleaning (hot water seems to work the best). It helps as well to have a wide tip to promote better heat transfer.

A conductive glue may also be considered for sticking the wire on the rail, for the S88 current is quite low, and the contact resistance can be rather large. (seen on other forum, but I don't know the reliability!) Fred
