The Blackpool branch lines run from the West Coast Main Line at Preston to Blackpool. The branch further splits into two branches at Kirkham and Wesham junction: the main electrified double track branch runs to Blackpool North station (Blackpool's main passenger station) via Poulton-le-Fylde, while a single track unelectrified branch runs to Blackpool South station via Lytham. The Preston to Blackpool North route was re-signalled and electrified, with electric trains starting running from the May 2018 timetable change.
