Improved Lego Interlocking Method
My previous machines used tensed thread to interlock the levers. My newer method uses 100% unmodified Lego, and is built with common parts. It is a very basic replication of tappet interlocking. As one lever is pulled into its reverse position is displaces the 1x1 round a half a plate into the gap on the adjacent tappet. This prevents the adjacent tappet from being reversed until the lever in reverse has been returned to normal. This basic principle is used to construct tappets so that arranging conflicting routes is impossible.
The machine controls five signals, that are part of an interlocking where three tracks converge to two. Each lever represents a route, either straight or diverging. Pulling the lever will clear a signal but, the actual aspect (y/y or y/r or g/r) is determined by the track circuits, not the lever.
It can be used with mechanical signals as well.
