Application #4

Alternating Two Trains at a Siding

See Application #4 from the "Applications Documentation Set" for details.

Description:

This track configuration allows two trains to alternately run around the layout. When one train enters the siding and passes over a train sensor, the other train will pull out and exit the siding.

Implementation:

In this track configuration, both of the sidings are isolated from each other, so that only one siding will have power at a time. The SwitchMaster controls the turnout, and puts power on the appropriate isolated siding. Since the SwitchMaster is using two different channels for sensors, this allows trains to PARK on top of the sensors with no ill effect. What this means, is that you can now add slow-down diodes or resistors in these sidings so that the trains creep into the sensor before they switch.

In addition, the SwitchMaster puts out a 1 second "burst" to the electric turnout when triggered. This means that it is impossible to overheat or damage electric turnouts. For switching reliablity, the SwitchMaster puts a pure DC voltage on the switch instead of a half-wave rectified AC signal. This gives MUCH more power to the turnout and eliminates the need for "boosters" or amplifiers to drive the switch.
