New for 2015 is a recreation of Platform 9 3/4, complete with British steam train no. 5972, which is better known as the Hogwarts Express. As well as standing on the platform for a steamy selfie, you can walk along the train's adjoining carriage and even sit in the interior carriage where Harry's chocolate frog escaped and the Dementors attacked.
Catching a cold or slipping in the slush is no longer a worry. London's spring calendar for kids has kicked off so release the little ones into the wild once again.
