The Drain in Network S.E. livery

One tends to forget about the Waterloo and City line. Even though it's just a stone's throw from where I sit, I think I've only used it about twice in 60 years.

I suppose it's rarely of any use to people who actually live in London, its target market consisting entirely of commuters into Waterloo main line.

This video clip reminds us that it used to be run by BR and was not part of the London Underground, and for a brief period its trains bore Network SouthEast colours, something I had quite forgotten.
