What is HS3?: Proposed sub-Pennine rail line explained
Reducing east-to-west journey times is a necessity for a prosperous north but how will that happen?
This is the name the government is giving to its ambition to speed up connections between the big cities of the north from east to west. At the moment, the £50bn HS2 network is planned to run from London to Birmingham and then in two forks north, to Leeds and Manchester. HS3 would provide faster direct links across the Pennines between the last two cities, reducing journey times across the north.
