There are “huge disparities” in the quality of train services in different regions of Britain, according to a report for the Campaign for Better Transport.
Services are best in London, the South-east and North-west of England, the West Midlands and Scotland. But services in Wales and East and North-east England perform worse.
And even though services in London are well-used and have benefited from major investment, passenger satisfaction "is hindered by concern about cost and overcrowding" the report says.
It adds there are improvements to be made everywhere, with services in Wales, for example, being less well-used and being less accessible than in other regions, as well as suffering low passenger satisfaction levels.
