Isolating track after ballasting?

[RobertInOntario]

It is fairly common to isolate ballasted track just as you stated. Carefully cut the rails and then glue some plastic in the gap, and carefully file it to shape. I think it was Russ that suggested using plastic bread wrapper clips for this purpose (the little rectangular plastic thing that holds the bread bag closed in lieu of a tie.) I'll be using a Dremel tool with a cutting disk to do my gaps.

Thanks, Gary. I'll try this then, following the previous suggestion but also inserting small pieces of plastic into the gaps as suggested by Russ. I'll try to save some of those bread bag clips then!
