[vanilla]. v.1.1.82: Changing a unique (or the last) TrainStop name will update the schedule of all trains with this TrainStop. Regardless of possible pathing.
Can be tested with the red or blue TrainStop. In case of the green TrainStop both stops will have to be renamed to update the schedule.
Duplicate TrainStop names can occur by renaming (i.e. rename "A" to "B").
Works with "Shift-Copy", Blueprinting or manual renaming.
Will not work on multiple surfaces.
