a direct move is performed in all cases, i.e. the fastest (shortest) possible move to reach<br />

the destination track. The bridge is assumed to be occupied if the indicator element associated<br />

with the bridge is turned on. If no indicator element is associated with the<br />

bridge, then the specified move is performed anyway.<br />

Since a direct move is more prototypical in cases where no engine is located on the<br />

bridge, it is recommended to assign a feedback indicator to the bridge, if possible.<br />

Otherwise TrainController is not able to determine if the bridge is free or not<br />

while deciding to perform a direct move or not. Without a feedback indicator assigned<br />

to the bridge TrainController will never perform a direct move when under<br />

control of the Dispatcher.<br />

Usually you will also associate a block of the Dispatcher with the bridge of an<br />

automatically operated turntable. Stop indicators assigned to this block are<br />

needed to stop each engine automatically at the correct location on the bridge.<br />

The only other thing you will have to do is to adjust the turn boundary carefully. The<br />

rest is done automatically by the software. In the usual case where a turntable is located<br />

in front of a roundhouse you will adjust the turn boundary in a way that the accessing<br />

tracks are located on one side of the turn boundary and the roundhouse is located on the<br />

other. In the diagrams displayed above you can assume that three accessing tracks are<br />

located on the left side of the turn boundary and the roundhouse is located on the right<br />

side.<br />

More generally the following rule applies: if the tracks connected to a turntable are associated<br />

with blocks, then the blocks located on one side of the turn boundary face the<br />

turntable with their right exit, the blocks on the other side of the turn boundary face the<br />

turntable with their left exit. This is illustrated in the following diagram:<br />
