Good video here showing the challenges faced by BR and the N.S.E. regions prior, and during the privatisation phase of the railways in the UK. Lots of old EMU stock at the time and lots of problems with delays. Great efforts by staff and genuine railway people in keeping the trains running. I don't know if privatisation improved things or not? There was a lot of investment in new trains etc from the 1990s and that would have had to happen either way.
