Why does the steam locomotive shown have two independent sets of driving wheels. They would never work that way because this is an inside - cylinder locomotive. This locomotive is supposed to be an 0-4-4, not an 0-8-0. The flues and pipes would have to be designed to essentially rotate to accomodate the 'bogies' of driving wheels. This works on outside cylinder engines, but not inside cylinder engines because the cylinders are inside the frame.
Lol sorry

The train depicted at 3. 20 is wrong those locomotives were used on the Metropolitan cut and cover and were built around 1926 they were too big for the deep tube.

This video is a bit ambiguous about one major fact; all these original subway/tube systems were built by private enterprise, not governments.

I wish they had said something about operations -- imagine how much you would get gassed every day by riding behind a steam locomotive in a tunnel.

and then you come to kolkata and realize they still cant implement a technology in 10 long years that has been around for over 100 years now.

That Metropolitan tank engine has two sets of driving wheels instead of one! It should be an 0-4-4 and you have drawn it as an 0-4-4-0!

You can see with the central line the cut and cover technique. All of their oldest stations are under main roads rather than to their sides
