Semantics

Best Practice / Examples

Indication of midnight overruns

Day offset is used to define whether a block connection (in railML® 2 <circulation>) includes none, one or more than one midnight overruns when validities with more than one operating day are used.

Interpretation a) assumes that both block can happen after each other on the same day by setting offset to 0.

Interpretation b) - block 2 is executed on the next day after the execution of block 1 by setting offset to 1. The vehicle is not planned for the whole weekend. After the block1 on Friday it continues with block2 on Monday. There is day offset is three nights. For this case there is a need of two block connections.
