Hi again, got a problem with a left hand point. I put a loco into a siding, then switch the point to isolate the said loco. The problem i have got is that, when i run another loco going forwards, on the main line, The loco in the siding also moves. Another problem is the voltage reverses when i get past the said point. What is happening ? Is it a faulty point ? It is an insulfrog point.
