A heritage railway line has apologised for allowing the attraction to be used to shoot a hardcore pornography movie.
The Epping Ongar Railway, set to host an Easter egg hunt this weekend, featured in a video by adult film company Brazzers.
Dean Walton, business development manager at the heritage railway in Essex, apologised to customers for what he called "an error of judgement".
He said any further approaches for such productions would be refused.
Ongar station is clearly recognisable in the opening sequences of the 28-minute movie.
Mr Walton said the railway, which describes itself as "family friendly", had been made available for commercial hire "on a number of occasions" to generate money to run the trains.
He said: "Earlier this year we took a decision to allow an adult film, subject to certain conditions, to be filmed on the railway.
