    I see GA have a "shortage of traincrew" tomorrow and have cancelled about 50 trains for tomorrow, PG coded of course so they won't be counted against ppm. Hertford branch be damned.

    A measure of performance you can believe in for honest reporting. well, sort of, ish, anyway...

    What does PG coded mean?

    Suitable for general viewing, but some scenes may be unsuitable for young children. ;)

    Oh, you mean in railway delay attribution? That's a planned cancellation by the operator.

    It's only fiddling if they got the cancellations uploaded by 2200 last night, hence making them STP (Short Term Plan) alterations. Later than that and PPM is measured against the timetable that would otherwise have applied.

    What penalties will GA incur for these cancellations?

    One thing that irks me about performance statistics is that trains which are cancelled are not included in the punctuality measures. After all, a cancelled train can't be delayed. It's as if to say that had the train actually run it would have been on time. But it didn't so it wasn't!

    There is a performance metric called CaSL, Cancelled and Significantly Late, so it is measured.

    Cancellation have quite tight benchmarks as well - at least 99% in some cases.

    That's not accurate:

    Trains fail PPM if:

    (1) It does not start where it should start;
    (2) It does not finish where it should finish;
    (3) It doesn't stop at all the stations it should do;
    And
    (4) It arrives at its terminus 5 minutes (or 10 minutes for Long-Distance) or more late.

    As such, cancelled trains fail PPM.

    However, as these trains appear to have been P-Coded and are therefore not in the "Plan of the Day", they can't fail PPM in the first place, as, it was not booked to run in the first place.
    --- old post above --- --- new post below ---
    The train has to be part of Plan of the Day to be measured under CaSL.

    Exactly so. As long as they got them to NR before 2200 last night they won't hit PPM. They might get some tough questions from DfT though; I know FCC did when they did something similar due to a driver shortage.

    As I understand it, AGA are in profit sharing, so DfT will bear half the cost of the revenue hit from cancellations.
