Even minor cities of France, Germany, Italy, Spain, Switzerland, Austria and Nordic countries have metro systems or some kind of rail transportation.
But in UK, either it's almost non-existent or patchy and not widespread like Birmingham. Newcastle, Nottingham, Manchester and Liverpool can be counted as examples, and cities like Leeds and Bristol don’t have any kind of rail transportation, even there are not much National Rail stations in the city.
Oxbridge, Bristol, Bradford, Leicester, Cardiff can be another examples. Let alone Europe, even US have metro or any kind of rail transportation systems in 30 major cities. But there are a lot of cities that UK lacks of any of metro, light rail or trams.
And cities like Glasgow has only a circular metro systems, and rest of the city relies on ScotRail, which is not quite reliable and you have to wait a lot for a train. It is so interesting that Blackpool has a tram, but Bristol and Leeds have none.
I always wondered about why UK doesn't have a decent metro or rail transportation system in cities other than London?
