Key service changes:
The one-day DLR strike for New Year's Eve by the RMT isn't the only walkout planned for the festive period.
The RMT has also announced 24-hour industrial action on Greater Anglia on the 27 December, and on 31 December on South Western Railway in separate rows over the role of the guard.
SWR is putting in place contingency plans, which it said should keep passengers moving if the strike goes ahead, with details of those to be announced.
Greater Anglia meanwhile, said it already had a revised Christmas service in place on Wednesday 27 December, along with alterations due to engineering works. It plans to run that revised service, but will also confirm full details closer to the date.
Meanwhile, the strike action won't be ending anytime soon, as the RMT has announced a batch of new strike dates in January across Northern, Merseyrail, Greater Anglia, South Western Railways, Southern and Island Line services.
When to travel
If you have any choice in when you can get away on any Christmas travels this year, the date to avoid looks to be Friday 22 December.
The RAC has dubbed it "Frantic Friday", expecting roads to be the most congested then, with 1.25m leisure journeys racked up as last-day commuters cross paths with drivers heading home for Christmas.
