Getting another switch is the easy solution but doesn't really address the situation, especially if there is another short somewhere that is causing the intermittent failure. I am thinking of replacing all my tubular track with Gargraves track and compatible switches. Even my old engines seem to go into the shop for repairs twice a year which is prompting me to go with more modern (but not digital) conventional engines just so I don't have to run around dealing with derailments while guests view my layout. After all, who needs the frustration?
