Brighouse railway station was also seen in the opening scenes of the first episode with a Northern Rail service seen arriving and then departing the station. Many exterior scenes, including Market and outside street scenes were filmed in Dewsbury and Dewsbury Town Hall was also featured. The exterior shots of 'St. Mary's Hospital' is actually the exterior of the 'EC Stoner' Administration building of the University of Leeds and the Mosque shown is actually the Northern School of Contemporary Dance on Louis Street, Chapeltown. Many of the Victorian housing stock seen on screen are Leeds streets filmed around Harehills. All scenes involving the British Rail Class 101 Diesel Multiple Unit were filmed at the Ecclesbourne Valley Railway in Derbyshire. This type of train is no longer in service - the last serving unit was withdrawn in 2003. Certain scenes were set in Scarborough, due to a particular character being resident in the town. Wirksworth station was dressed up to be 'Castlebury' station and the Class 101 DMU had the fictitious 'Pennine Rail Express' livery applied to the interior and exterior of the train - the colours of which are of a similar style to those of the Northern Rail train livery. Some Northern Rail trains can be seen pulling out of stations and in the backgrounds when not central to the main action within a scene.
