I don’t know if you’ve been to london, but if you’re a standard “modern” height for a man you can barely to not even stand straight in the deep tube trains. They are very very small, and limited by the tunnels which are absolutely tiny. I’m not surprised fitting air conditioning is a challenge, even ignoring the ventilation issues which are also massive.

a consequence of having the first subway in the world i think.

  Yep, same as many other things we take for granted in modern constructions, such as accessibility, good signage, enough space on stations and tunnels for easy flow of passengers, platform screen doors, etc. It's a no brainer when building today, but wasn't back then, and retrofitting is extremely complex and expensive.

You should see the Glasgow Subway - its trains are almost comically small.

  The entire network is a single line which circles the city, the map shows 2 lines, one clockwise, one anticlockwise. The trains have a dirty orange livery, hence the local name: The Clockwork Orange. My favourite underground in the UK.
