The '''Calder Valley line''' (also previously known as the '''Caldervale line''') is a railway route in Northern [[England]] between the cities of [[Leeds]] and [[Manchester]] as well as the [[seaside resort]] of [[Blackpool]]. It is the slower of the two main rail routes between Leeds and Manchester (the other being the [[Huddersfield line]]), and the northernmost of the three main trans-Pennine routes.
