The Leeds–Bradford lines are two railway lines connecting the cities of Leeds and Bradford in West Yorkshire, both meeting in Leeds railway station and are included in the West Yorkshire Metro area system of lines.

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.
