T must not depart Z until X mins after Y has finished joining.
This rule forces train "T" to wait for a period of time at any timetable location Z relative to the time of completion of a join involving train "Y".
The join must be effected at the same location as the train T is being held.
The reference to Y can be to any train being joined but T need not be involved in the join itself.
| For example: 1A00 can be held at the station while 1A01 and 1A02 join at that same station. |
