yeah thats brilliant. you should check out pictures of moscow metro in russia too. the designs are amazing and is a tourist attraction in itself that you can spend hours riding the metro and exploring it all.
most of the best stations where built in the few years before ww2 when they thought it likely they where going to have to spend allot of time underground, so they set all their best arcitects on it as they thought that nothing was too good for the russian working class and it was another way to try and upstage other countries like the U.S too.
