The train carriage featuring on Saturday night's show also appeared in porn flick Nympho

Beeb bosses have been left red-faced after a train used in the Strictly Come Dancing opening sequence also appeared in a X-rated adult film.

The Strictly professionals and a cast of celebrities will be seen boarding the Strictly Express as they are ushered in by train guard played by judge Craig Revel -Horwood.

The carriage which features in a video clip to be screened on Saturday night also acted as the backdrop for ‘Nympho’ starring Amirah Adara and Danny D.

The saucy film tells the story of an 18-year-old girl who uses her journey to school to cop off with strangers.

In the raunchy flick the school girl is filmed in a steamy tryst with a man in one of the vintage railway carriages.

Earlier this year Epping Oncar Railway came under fire for its controversial dealings after parents complained about the nature of films being shot there.

The train is used for Santa Specials, Peppa Pig meet and greets and other family friendly events.

The railway business development manager of the Essex based set told The Sun at the time: ‘Filming took place on a day when the railway was closed to the public.

‘We are clear that in a case where content could be unsuitable for a family-friendly attraction, we would turn down the booking.’

One mum ranted at the paper: ‘One minute it’s Peppa Pig and Father Christmas, the next it’s an orgy train.

‘I’d be reluctant to take my kids on there again knowing that has gone on.’

This year’s Strictly Come Dancing has so far come under criticism for the lack of recognisable faces in the line-up.

But one thing’s for sure, there is plenty of eye candy!

The Wanted’s Jay McGuiness, Olympian Anthony Ogogo and hunky Peter Andre will keep us firmly glued to the box this series.
