Although diesels sometimes run on the line, it is primarily a preserved steam railway and was used in the film 'The Railway Chikdren.'

I have listed it under Oxenhope because that is the terminus not contained in its name. No prizes for getting the other one!
There are loco sheds at Haworth and a museum at Ingrow [West,] both stations on the line.
