The Morecambe Branch Line is a railway line in Lancashire, England, from Lancaster to Morecambe and Heysham, where trains connect with ferries to Douglas, Isle of Man. To reach Heysham, trains must reverse at Morecambe. Almost all passenger services are operated by Northern Rail. Most are shuttles between Lancaster and Morecambe, continuing to Heysham only to connect with ferries, primarily using Class 142, Class 153 or Class 156 diesel multiple units . A few services continue beyond Lancaster to Skipton and Leeds (see Leeds-Morecambe Line), and generally use Class 144 or Class 150 units.
