New Years Day transport in London

[whatkatydid2013]

Anyone who lives in & around london know what time tubes/overground started running on New Year’s Day in previous years?
Planning a few days stay and we need to travel in from Watford on the 1st so trying to get an idea when we could reasonably expect to arrive. Will appreciate any advice you have :)

Transport does run on NY Day. Typically they follow a 'Sunday service' timetable.

Thanks. I’ve read on the train providers site that they start late but can’t find a time
