Bi-Directional Operations 

For this BitSwitch the general rule of one (1) track contact per isolated section applies except for an additional contact that is needed just before the trains enter the Single Track portion of the layout (contacts 2 & 4). As with all other BitSwitches, contacts can be shared.

[when using “Brake on DC” option
engine decoders
 must brake in both directions]

 

The DT-ST-DT BitSwitch provides automatic control when trains exit from Double Track main and enter a Single Track section of the road.  This BitSwitch will allow bi-directional traffic on a Single Track main line.

When the "DC Brake Generator™" is set for automatic operation this DT-ST-DT BitSwitch™ provides automatic collision protection when  dual tracks converge to a single track main line.

When a train enters a block controlled by the "DT-ST-DT BitSwitch™" from either direction the BitSwitch checks for the following:

Is the bi-directional single track segment occupied?

Has the preceding train traveling in the same direction failed to reached the next dual line and trip the release trigger?

Does a train approaching from the opposite direction have right-of-way?

If the answer to any of the above is YES the train will slow to a stop.
When the answer to all three questions is NO the train will enter the single track segment.

The DT-ST-DT Bitswitch can be combined with additional Block BitSwitches where Block BitSwitches are added for track segments A2,A3 and B2,B3

The track contacts for this BitSwitch may be shared with adjacent BitSwitches.
