• Connect the reed switches to push-switches A and B (see the stripboard layout).
• The switches can be held in place between the rails with a small piece of blu tac.
• Connect the track wires to the COM and NC contacts of the relay.
• When soldering to the track make sure you solder to the outside of the rail.
• Each locomotive will need a miniature magnet glued to its underside - test first with blu tac, but superglue is probably best once you are sure it is in the correct position.
• Note that railway signals have red at the bottom, unlike road traffic lights where red is at the top.
