RTT difference between GBTT and WTT

[800Travel]

Hi,

Wondering what the difference between GBTT and WTT is on Realtime Trains please?

I'm keeping a 'mileage log' this year, including the scheduled and actual running times. For the actual running times, I'm using the 'realtime' column but for the scheduled times I'm unsure what to use. I've currently been using the WTT, but noticed these differ. For example 11:12 GBTT vs 11:11:30 WTT (and 11:12:15 but I expected the realtime column to differ).

Any thoughts please?

Thank you

Use the WTT, that is the actual plan. GBTT has to be on a full minute.

WTT is the Working Timetable, see https://www.networkrail.co.uk/running-the-railway/the-timetable/working-timetable/ , timings on a 30 second granularity and often differs from the advertised GBTT "public" timetable times at https://www.networkrail.co.uk/running-the-railway/the-timetable/electronic-national-rail-timetable/, for example working timetable departures are often 1 minute later than advertised so that trains can leave at the advertised times and gain some timing leeway. Trains should never depart earlier than the publicly advertised times, except for the "fudge" that now exists for departures from some terminal stations where they are allowed to leave early.
Half minutes are rounded for the public timetable - up to the next minute for arrival times and down to the minute for departure times.
WTT times aren't as granular as quarter-minutes, though, and public times are only on one minute granularity, as observed above.

Onn occasions there can be several minutes difference between working times and advertised times, particularly for set-down only stops and for those late night trains that are frequently affected by engineering works.

Journey planners for passengers always use the advertised times.

Thanks all.

For purposes of delay repay, which one do train operating companies use please?

I.e. if GBTT said 12:00 and WTT said 11:58 and the train arrived at 12:29 and the TOC does Delay Repay for 30 minutes or more.

Delay Repay eligible or not?

Thank you

The GBTT so no delay repay would be due.

GBTT, as that's the 'advertised' timetable - i.e. the one given to the public.
