Change of Origin

Overview

When a train is due to start from a location other than the first location in the schedule, a change of origin message will be sent.

Trains may start from an alternative location for two reasons:

  • When the previous working is terminated short of its destination and the return working will start from that location
  • When the train starts from, for example, Doncaster North Yard rather than the schedule location of Doncaster South Yard
