I don't like the Marklin Z isolator tracks much. They place an unslightly connector tab beside the track which I have to figure out how to cover up, and the flat plastic on the roadbed I am finding awkward now I am starting to ballast. I am wondering about eliminating them and cutting a break in an ordinary piece of track instead and soldering wires to it. I have never done this before and would appreciate input from anyone who has experience in this or who has done any direct soldering of wires to track. Thanks !
