Diagram 103: 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 and 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 and the<br />

train must not proceed.<br />

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

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

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

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

behind of this route are reserved, too. This is done to reserve and activate the route in<br />

time before it comes to unintentional train stops caused by long lasting route activation.<br />
