It is a film that holds a special place in the hearts of film-goers five decades after its release.
Now fans of The Railway Children will be able to rediscover the magic with the sequel The Railway Children Return, which begins filming in the UK next week.
Actress Jenny Agutter will return as Bobbie Waterbury, the character that propelled her to stardom when she was just 18 years old.
Now 68, Jenny's career has gone from strength to strength in the decades since. She has won a BAFTA and an Emmy and for the last nine years has starred in hit BBC drama Call The Midwife as Sister Julienne.
