In conjunction with the possibility to select successors randomly it is possible to control<br />

a hidden yard automatically. A train arriving in a hidden yard can be enabled to select<br />

another waiting train, which will leave the hidden yard.<br />

If it is intended to start the successor with the same train, then it is recommended,<br />

that the successor starts with a destination block of the previous schedule. In this<br />

block the control of the train is transferred to the successor.<br />

It is also possible to specify that all listed successors are started. These successors are<br />

started simultaneously, when the previous schedule is about to be terminated.<br />

If several schedules shall be executed in a sequence, e.g. schedule 2 shall be executed<br />

after schedule 1 and schedule 3 shall be executed after schedule 2, then<br />

schedule 2 is to be specified as successor of schedule 1 and schedule 3 as successor<br />

of schedule 2.<br />

Since it is not possible to reverse a train or to change trains during the execution of a<br />

schedule successors must be used if<br />

• a train shall be reversed<br />

• trains shall be changed<br />

5.14 Schedule Selections<br />

Sometimes it is desirable to select one of several schedules. This is supported by schedules<br />

selections. A schedule selection enables the selection of certain schedules out of a<br />

selection of several other schedules. Even though there is schedule diagram associated<br />

with a schedule selection such selection can be started like any other normal schedule.<br />

It can be used wherever a normal schedule can be used. When a schedule selection is<br />

started then one or more of the schedules contained in the selection are selected and<br />

started. This selection may also include other schedule selections.<br />
