As someone who is lucky enough to live 'where the trains run on time', the prices, availability and standards of regional services I use when I come back to the UK are frankly appalling compared to some in Europe. (When I've been on UK long-distance services these have seemed improved over the years.)
Many trains are filthy and old and the pricing appears designed to rip the consumer off. (For example, when I am travelling from relatives to Liverpool a ticket for the full journey costs more than double splitting the journey in two and buying two tickets for the same services.)
Today I was on the train twice. The two were run by rail services of different countries. (I live near the border.) Both were modern, smart and spotless. Both were exactly on time (travelling through fresh snow in 'difficult' countryside). I have a rail card (available to anyone living in the country for €100,- annually - I got mine for €50,- on a special offer) and so the journey cost me €1,20 each way. (Normal price €3,50.)
A similar single journey - distance and time - from where my sister lives in the UK would cost £7.30 on a grubby overcrowded three-carriage regional service.
