What happens to your shift during the night tube service when the clocks change if you are a driver? Do you work an extra hour?
And what happens to the timetable - which I assume is all pre-programmed into the computers controlling the signalling equipment, e.g. central line? Was this the first time (in history) that the clocks changed in the middle of the live service?

I think previously the timetable, etc. just continued to operate on BST/GMT (as appropriate) until 04:30 but I don't know.

It's programmed into the computers.
Staff that work on night shifts when the clocks change get an hour's overtime.
Funnily enough, we don't get an hour taken off us when the clocks go forward.

Services have run all night on new years eve since the millennium.
Metropolitan and circle computers hate it and do all sort of strange things like offering wrong routes and not clearing signals for no reason at around 2.30 am. I think their computers have to be rebooted daily.

An interesting quote in the Night Tube timetable notices operating at the weekend:

What happened on the Victoria Line was that the clock on the dot matrix went from 01.59 to 01.00. I watched it click over and wept as that hour started all over again! And all the trains showing fell off and it stayed blank for several hours before it came back correct. And I spent those hours repeatedly saying to customers that the trains are running but the dot matrix fell over when the clocks went back.

I think their computers have to be rebooted daily. From what I can remember the timetable manager shut down resulting in no auto routing, but it's been a few years. I certainly remember the service still being put to bed one night when the clocks changed (I think they were gaining an hour) which was a bit different. |

On the night buses, didn't the rule used to be that journeys starting before 0200 carried on as if the clocks hadn't changed; journeys scheduled to start after 0200 ran as if they had? Quite what happened about positioning stock and crew if the timetable wasn't a repeating hour wasn't clear. But - pre-computer... rheostar - the staff are lucky, then. My father-in-law, who was a foreman at British Steel, used to work over the change with no adjustment either way; it was assumed that, over time , the swings matched the roundabouts. |

BTW, should have added that some operators - notoriously Barcelona - operated a 26 hour clock just to deal with night services and the things that went bump when the clocks chsnged.

Clearly nothing like being prepared for any eventuality. I wonder if they work to a similar Catalunian time zone in Cathedral construction? |

Try working through the peak with no DMIs and the service being disrupted - having to tell a handful of customers a ten minute service is running normally is easy!  |

We ran on amended duties for clock change night and some of us did up to an hour's overtime.
My own duty for instnce, started about an hour earlier than usual and finished about 30 minutes earlier than usual, giving me about 30 minutes overtime.
While LU officially turned back the clocks at 3am during the timetable change, all of the clocks on the platform and in the cab changed at 2am, leaving us in limbo to work the time out ourselves for an hour

That long night was my last which made the extra hour all the more painful. Back on days now, on the City group of the Northern line with far more disruptions than I'm used to. |

But surely, if the clock changes during the night, the trains will be 1 hour out in respect of the WTT? And with trains stabling and starting up over the night / morning period, how is that managed? You can’t fit a 4 hour night service into 3 hours and have the trains starting and stabling in the same positions and timings as normal.
