Jericho

According to Wikipedia, "Jericho is a period drama series created and written by Steve Thompson and directed by Paul Whittington. The eight-part series premiered on ITV on 7 January 2016. It is set in the fictional town of Jericho, a shanty town in the Yorkshire Dales that springs up around the construction of a railway viaduct in the 1870s. The series re-imagines the story of the building of the Ribblehead Viaduct, which is renamed the Culverdale Viaduct in the show".
