Diagram 119: Reservation of the Block ahead<br />

In the situation displayed above the train has just entered block “Main Line East” (displayed<br />

in red). The block ahead is reserved for the train.<br />

If there is a route located between the block <strong>and</strong> the block ahead, then this route is activated,<br />

too. A route is assumed to be located between two blocks, if it connects these<br />

blocks in the schedule diagram.<br />

If it is not possible to reserve at least one block ahead of the train or if the route to this<br />

block cannot be activated, then the signal at the related block exit is set to red <strong>and</strong> the<br />

train must not proceed.<br />

The Dispatcher follows different strategies to reserve the next blocks <strong>and</strong> routes.<br />

By default, the Dispatcher applies a smart mode. This means: when a block directly<br />

ahead of the train is about to be reserved, then the Dispatcher checks, whether there is a<br />

route behind the block ahead. If this is the case, then this route <strong>and</strong> the block behind<br />

this route are reserved. This is done to reserve <strong>and</strong> activate the route in time to prevent<br />

unintentional train stops caused by long lasting route activation.<br />
