Can you link to the Munich or Amsterdam metro trains? I just see fairly ordinary metro trains for a system with normal-size tunnels. The design is irrelevant to the small tunnels of the Piccadilly Line. https://en.wikipedia.org/wiki/MVG_Class_C https://en.wikipedia.org/wiki/MVG_Class_C https://commons.wikimedia.org/wiki/Category:M7_(Metro_Amsterdam) https://commons.wikimedia.org/wiki/Category:M7_(Metro_Amster... A better comparison is with the Circle/District/etc lines. Those trains are of similar size to the Dutch and German ones, although I think they are designed to carry a lot more people so there are fewer seats: https://en.wikipedia.org/wiki/London_Underground_S7_and_S8_Stock https://en.wikipedia.org/wiki/London_Underground_S7_and_S8_S...
