I need some advice quick as the clan is coming over tomorrow for Christmas day. All of a sudden, the switch on one of the loops is not swinging back all the way which is causing the loco to enter the reverse loop from the wrong direction. the switches on either end are just spring loaded and have always worked just fine in the past. But the one now on the right side of the mainline, after a few loops through the thing appears to be very sluggish in springing back and is not spring back all the way causing the loco to derail.
Any suggestions on how to get this this to snap back as it has always done in the past or why this would be happening all of a sudden?
