we were brought in on the wrong platform, why the signaller couldn't just hold us for an extra 3 minutes at the junction is beyond me. [/person A]
[person B].... because the signaller was probably fed up at getting delay minutes allocated to him for making a regulating decision.
Example:
- We can have a freight train enter our area Right Time, gets held in the middle for a passenger train and arrive late at a second regulating point 5 minutes late.
- It is booked to be held at the regulating point for 35 minutes.
- When it leaves the regulating point it is 3 or 4 minutes early (but in its right pathway)
If the freight was booked to time, track defects mean that the passenger train would be 5 or 6 minutes late to destination.
With the freight being held, both trains get to destination on time. It does not inconvenience any other service and there are no crew changes or anything that would be affected.
Logic would tell you holding the freight is the right thing to do. Each train gets to it's critical points on time (station stops, destinations).
What actually happens is the delay to the freight for holding it is allocated to the signaller and (theoretically) anything from £80 to £400 a minute of delay is passed from the Infrastructure Operator to the Freight Operator.
(of course - delay payments, etc, is just a paper exercise, but it still auditable)
So the signaller can be stuck between a rock and a hard place. The
