I imagine most modellers will know a lot more than me about making track reliable. I have picked up the following tips.
- Don't have step changes in rail height. check fishplate joins carefully - particularly if plastic fishplates have been used for isolation.
- Rail height through points at crossings is critical . Mark the rail tops with a magic marker, then file out the whole point with a flat file until all the marking has gone.
- Avoid sudden changes in angle. Be particularly using flexitrack on curves: it is hard to get the last 10mm to follow the radius. I removed the sleepers and "pre bent" each rail to try to help here.
- The very end of the point switch blade can stick out. If this happens, insert a piece of cardboard behind it then gently file the blade.
