Britain's upcoming budget will invest almost £7.0 billion ($9.6 billion, 8.3 billion euros) on transport outside London, the Treasury said on Saturday, as part of plans to cut economic inequality.
Finance minister Rishi Sunak will unveil the transport initiative during his autumn budget and spending review due on Wednesday.
His Conservative party won a swathe of seats in northern England on a promise to deliver Britain's Brexit divorce from the European Union, as well as boost jobs and growth.
Recipients of the transport project cash include regions in the former Labour "red wall" that turned Tory blue two years ago and will be seen as payback for their support.
According to the finance ministry, the government will invest £5.7 billion in city regions to boost productivity via train and station upgrades, and tram network expansion.
It will also inject £1.2 billion into overhauling bus services.
The government wants to quicken journey times, simplify fares and increase services outside London, after repeated complaints that regions outside the British capital were ill-served by transport links, affecting business.
"This transport revolution will help redress that imbalance as we modernise our local transport networks so they are fit for our great cities and those people who live and work in them."
Transport policy is set separately in Scotland, Wales and Northern Ireland by the nations' devolved administrations in Edinburgh, Cardiff and Belfast.
The government said the extra investment for England would mean additional cash for the three other UK nations under weighted public expenditure adjustments.
Chancellor of the Exchequer Sunak will also announce the latest growth forecasts for the economy, which is battling high inflation due largely to surging energy prices and a supply chain crisis that was sparked by Brexit and Covid.
