Duke of Lancaster is one of the last surviving railway steamers in the UK. She was built in 1956 to carry railway passengers over the Irish Sea from Heysham to Belfast. She was also used for cruising on European waters until 1966. In 1970 she was converted to a car ferry. She was laid up in 1978 and sold to a company for use as static amusement ship, known as "Fun Ship". It has been slowly rusting and deteriorating for many years and her future seems uncertain.
