An <b>exclusive zone</b> is a track section which can be occupied by only one train at a time. Exclusive zones are marked with a blue band in the middle of ties. By default, every bi-directional track starts as an exclusive zone.

Any neighboring tracks that are marked as exclusive zones will be considered one contiguous zone, regardless of the track directions.

Tip: Hold <b>{0}</b> while using the <b>{1}</b> tool to toggle exclusive zone of an entire track segment at once.

When to remove exclusive zones

There are cases where the default exclusion zone on bi-directional track is not desired. For example, when connecting a double-track main line to a multi-track terminus station from. In this case, it is common to first converge the main line (1) to a bi-bidirectional track (2) and then split it to terminus stations (3). The bi-directional segment between the main line and stations (2) should not be exclusive, otherwise it would form, together with all lanes of the station, one exclusive zone and no more than one train could use the station.

When removing an exclusive zone from bi-directional tracks, <b>always replace it with a no-stopping zone</b>. Having a naked bi-directional track without exclusive and no-stipping zones will almost certainly result in trains blocked head-to-head.
