This 'Page B' describes operation of the unit as a 2-track S gauge "Automatic Passing Siding" for controlling 2 trains.

The following 'Page C' describes addition of a relay, to control 3 trains with the same track unit.

[full size drawing]
This drawing is similar to the unit built in Photos 1, 2, & 3 above, but is simpler. It does not have the rheostats nor a "slowdown" section,
nor does it have the "block" control to operate the 3rd train.  Mark also has it designed so that it can be operated in either direction.
