From First Great Western ...
Christmas Eve Timings of trains will start to change from 1700 across the network, and from 1500 in the London and Thames Valley area. The last train will leave Paddington before 2130.
Christmas Day and Boxing Day No scheduled train services.
27 December Local services into London will start from around 1100 because of work in the Hayes and Harlington area, and long distance services into and out of London will be limited. We are advising customers to use other routes where possible, or to travel after 1100. Tickets will be valid on other routes.
27 December - 4 January A reduced timetable will operate and diversions will be in place. Journey times may take longer than normal.
We have set out the changes in detail for each route on our website on
