The term "nationalisation" has been used for however many years* to describe a railway network which is owned and funded by the government. TfL gets some of it's money from government funding, but I'm not sure if this means it is nationalised.Why is 'nationalisation' assumed to mean 'owned & controlled by one central government in Westminster' ?
Are the tram/metro systems in the UK not effectively nationalised?
Is TfL nationalised?
If the Scottish or Welsh govs took over their rail franchises at the end of the current ones, wouldn't that be nationalisation?
Merseyrail must be close to being nationalised, the infrastructure is NR & the new fleet is owned by Merseytravel.
West Midlands Railway brand is owned by TfWM.
If the Scottish or Welsh governments took over the rail franchises in their specific countries, then yes; the routes which are controlled by them would be nationalised.
Merseyrail is not nationalised as it is owned and run by Serco-Abellio. The infrastructure is owned by NR, yes, but so is 99% of the UK railway network. If that's your definition of close to nationalisation, the whole network is pretty much there.
West Midlands Railway is not a nationalised system as it is owned by private companies and is therefore privatised.
And as for "once central government in Westminster", as much as you may not like it, Her Majesty's Government is accountable to Parliament, and the Parliament just so happens to be in Westminster because it is in the centre of London and seen as London has been a major city since the year AD 47, it was considered a sensible decision to put it there.

*Really, the railways were nationalised in 1948 and so this term has been kicking around for 71 years this year.
Also, Birmingham Moor Street is a far better (and Chiltern) station.
