“Protection <strong>and</strong> Locking with Conditions”. They are valid for all schedules, that use<br />

these blocks or routes.<br />

Conditions can also be specified on a per-schedule basis, while editing the diagram of a<br />

schedule. Conditions specified in this way apply only when this schedule is being executed.<br />

Such local per-schedule conditions are always only valid for the schedule they<br />

have been specified for, other schedules are never affected by these local conditions.<br />

Critical Sections<br />

In the diagram displayed below “Main Line East” <strong>and</strong> “Main Line West” are specified<br />

as critical sections. Critical sections are displayed on the computer screen with a blue<br />

marking.<br />

Diagram 162: Critical Sections<br />

The most usual application of critical sections is to protect opposing trains from deadlocking<br />

each other. If the Dispatcher encounters during reservation of the next blocks<br />

ahead, that a block is marked as critical section, it will continue reserving further<br />

blocks, until a block is reached, that is not marked as a critical section.<br />
