The Airedale line is one of the rail services in the West Yorkshire Metro area centred on West Yorkshire in northern England. The service is operated by Northern, on the route connecting Leeds and Bradford with Skipton. Some services along the line continue to Morecambe or Carlisle. The route covered by the service was historically part of the Midland Railway.

Metro is the passenger information brand used by the West Yorkshire Combined Authority in England. It was formed on 1 April 1974 as the West Yorkshire Passenger Transport Executive (WYPTE), at the same time as the metropolitan county of West Yorkshire. The Metro brand has been used from the outset and, since the formal abolition of the WYPTE on 1 April 2014, it has remained the brand name of public transport in the region, overseen by the West Yorkshire Combined Authority, which is also responsible for the delivery of transport policies.
