Secrets of the London Underground

I was travelling up to London from Essex from age 11 to nearly 59 years old. It was something I had to do, was not a big fan, dirty, squashed on the dreaded Central Line, but as with most things in life, when it's gone you miss it. Started working from home, and now actually miss the daily routine, so this series in very interesting. Like in episode 2, "Mind The Gap" I know Embankment with well, but never realised that is the only platform I now hear that male voice.
