Is anyone familiar with the former K-Line superstreets system? Or the Bachman EZ Street system? Will the different track systems mate up, without a problem? It looks, from what I've seen, that the tracks will mate. I'm trying to find either the K-Line D16 or D21 curves, and the necessary 2.5" transition sections of track. I've got several straight track sections, and a couple o railroad crossings but no curves. Didn't know what I wanted, or needed way back then! Was thinking I had everything I needed. Was maybe hoping I could incorporate the superstreets along with a smaller Lionel Fasttrack layout at club show next week. Any help and/or information much appreciated. Thanks.
