British Rail/Railways always got a lot of stick as a nationalised industry, but I always had good memories of my use of it before I bought my first car.
Bearing in mind that the railways were originally privatised because of the lack of investment from the previous big four private rail companies, British Rail did a lot to bring the railways into the modern post war era with the development of diesels, electrification and high speed intercity services with minimal government funding.
This article gives mixed pros and cons on the rail privatisation.
Personally, I always thought that the great Tory national asset sell offs were done to offset a necessary tax hike to bring money into the exchequer when an election was due.
In short we paid Tories for their votes with the various industry privatisations!
