Tube drivers are rather well paid - but, of course, that upsets those who don't like Labour, the Unions or workers being well paid.
If it were not for subsidies, there would be no railways - anywhere.
It might be considered odd to "privatise" a service by selling it off cheap and then have to "pay" the purchaser to run that service.
These payments are now known as "subsidies" but when it was in public ownership they were called "losses" and decried by those who sold it off cheap and used as a reason for doing it.
I'm sure that is not good business or even common sense but what do I know.
Renationalise the railways with no compensation and employ a Japanese person to run them.
