In reply to ck85:
I don't know whether it affects the trains but Xmas is not the same here. Xmas day is a church service and family day, most places will be shut. Boxing day is back to work until 3 King's Day on the 6th of Jan which is when pressies and stuff are given out.
So there is a better chance of trains running on 26th here but i am promising nothing - neither am i promising that the timetables you find will be correct, valid or in anyway useful ;0)
