Interesting to watch, yes, but had I known nothing about tube
beforehand I would have learned:-

1. There were no underground railways in London before the City and
South London Tube
2. This line was build using cut and cover methods

....

Indeed. By far the best method when tunnelling beneath the Thames.

3. It was steam powered.

Yes, the Paris section was interesting, and new to me, but given the
above I am not sure how complete a picture it is.
