Actress Jenny Agutter, best known for her performance in the classic film The Railway Children, is to renew her links with the movie and raise cash for charity at the same time.

Jenny, who spent weeks in the Worth Valley during filming 30 years ago, is due to visit Haworth on Sunday, September 17, to launch a six-mile sponsored walk in aid of the Cystic Fibrosis Trust (CFT).

She is a carrier of the faulty gene which causes cystic fibrosis and her niece, Rachel, suffers from the disease.

The circular walk will take in ten of the locations used in the 1970 film, including Three Chimneys, the Yorkshire home of the Railway Children, Oakworth Station and Mr Perks' cottage.

Jenny said: "The Cystic Fibrosis Trust really needs support as it strives to find a cure for this dreadful illness which affects over 7,000 babies, children and young adults in the UK.

"Since the trust was formed in 1964, the average life expectancy has risen from just five years to 31.

"It's a huge improvement, but still three young lives are lost each week in the UK to the effects of cystic fibrosis."

She is calling on people who want to take part in the walk to contact the CFT to get an official invitation from her.

Later in the day, she is due to attend a family fun day at Haworth Central Park, which starts at midday.

Susan Crossley, CFT regional manager, said: "The idea for the walk came to me when I was in the Tourist Information Centre in Bradford and I saw the Railway Children Walk leaflet. I did it and had a really good day and I thought it would be ideal for a sponsored walk."

She contacted Jenny who said she would be delighted to help and was looking forward to returning to Haworth.

People who enter will receive a certificate from Jenny who is due to launch the event and greet walkers when they return, before spending time in the park.

People wanting an information pack and registration form should contact Susan Crossley on (01274) 882898 or e-mail her on scrossley@cftrust.orq.uk

Cystic fibrosis is the UK's most common, life threatening, inherited disease. The lungs and digestive system are particularly affected. Secretions from various glands are think and sticky, instead of being watery and free flowing.
