Unsuspecting members of the public have been walking past Dereham's Memorial Hall, unaware of the dangers which lurk inside.

It comes following the arrival of the UK's biggest ever scare attraction on a train, brought over by American producers and scare attraction experts, Loco .

Horror Train will debuting at the town's popular heritage railway - the Mid-Norfolk Railway (MNR) - and rehearsals are already well underway at the town's Memorial Hall.

A group of around 60 actors are currently preparing to scare the living daylights out of thrill-seeking punters. They were chosen out of a pool of more than 500 who applied. Paul Goldsmith, workshop coordinator, said they had received applications from across the country.

'People want to be involved,' he said. 'There's such a following for it as well.

'I've been creating shows and selling them for many, many years. I've been fascinated by how we have managed to sell more than 7,000 tickets with giving away very little information.'

Mr Goldsmith explained that the time spent in the rehearsal process had allowed the actors to 'develop and grow' into their roles.

Burtie Welland, casting and script producer, is a former detective and, coupled with a background in writing, has been working on adapting the original script to incorporate the MNR's surroundings.

He said: 'The important thing is having a coherent story line which is going to get interest from people into what is going to happen.

'We are trying to take everything that everyone has ever been scared of and put it in the show.'

And not wanting to give too much away, he added: 'It's not always going to be the same experience every night for people.

'There will be lots of surprises along the way as we aim to utilise the train and its locality.'

The popularity of the event has meant that four extra time slots were added and people from as far away as Germany have purchased tickets.

Horror Train will run for ten nights, from Monday October 22 to Wednesday October 31, with a scare cast and crew of around 70. They will be chugging ahead on parts of the 20 miles of terror-stricken track. Only a handful of tickets remain. Visit www.horrortrain.co.uk for more information.
