This from Rudi over at Merseyrail...
Our walk-on fares aren't quite the same level as those for "Newquay to Kyle of Lochalsh" but then your whole family can travel with us for a Fiver!
During December up to two adults and three children can travel anywhere on Merseyrail's Northern or Wirral lines for only £5 on any Monday, Tuesday or Wednesday after 15:00hrs.
This great offer will be valid until 30th December 2009. For more details, ring our customer relations team on 0151 702 2071 or ask a member of staff.
And there is free parking at our stations too...
If you're travelling to Merseyside over the Christmas period why not take up Rudi's seasonal suggestion.
Not only is the train fast, cheap and easy, it's also less likely to be jacked up on bricks when you want to go home.
