Connecting the Unit
The track is divided up into a minimum of three sections, the main section and two
ends.
The ends are formed by isolating the right-hand rail by using an insulated rail joiner,
or by cutting the rail with a dremel or hacksaw. Fill any remaining gaps caused by
cutting with epoxy glue to ensure smooth running. This is not necessary at the
testing stage, but will ensure the final running is smooth.
The right-hand rail is relative to the forwards direction of the locomotive.
The length of the end sections of the track should be sized to allow for the loco to
enter, be detected and to stop. Carriages with lights which draw power from the rails
will be detected if they draw more than 4mA.
