With the UK having their share of railway reform (and love/hate relationship), I'm wondering if there's an objective assessment of the two countries' systems according to being on-time, being broadly available wrt place/time, pricing, and general customer satisfaction. The article mentions people blaming service deterioration on Deutsche Bahn being state-owned and without competition. UK should be quite different after Thatcher's privatization campaign starting in late 80s (been there in early 90s on a London station heading to the east, totally confused which train to board while being yelled at ^H informed over the speaker about the service provider/operator but not much else).
