Dan Padova,
I believe you are talking about the original post war Lionel Conventional Tubular. In reality there are three versions of the the Lionel conventional Tubular 072 Switches, the early 711- 072 Switches were the very best, built for Tin Plate Trains, Pre-War. The post war 072's were very good, and the modern Lionel 072 versions are nothing but trouble. Further the original K-Line Super Snap 072's were the very best low voltage 072 ever made, the RMT version of these K-Line Switches had some minor problems, that can be over come, and the newest version are just RMT's with different name on them.
Hope this helps a might. Purchase either the original Pre War 711, original post War 072 or the original K-Line Super Snap 072 Switches. The FasTrack 072 FTCC switches are also great stuff, that works perfectly on over 90% of all engines and rolling stock.
