Ain't it the truth.

Maybe I'm biassed because I can remember a time when the railways were
operated as a single entity with joined-up thinking!

And summers were warmer, too... I don't think it was ever the single
entity, but at least all parts realised that they were supposed to be
working together, and the differences between the entities (let's call
them regions) didn't actually bother the customers.
