National museum of computing [0] in Bletchley houses a rebuild of the Colossus computer. The people who volunteer there are great and always happy to explain the history.
PS. Bletchley is around an hour on the train from London Euston. Bear in mind that even though the museum of computing is located in the old Bletchley park complex, it requires a separate ticket from the main Bletchley Park museum.
