...but the actual oldest subway line in the world (between Paddington and Farringdon in London) works great. Recently got CBTC enabled so can handle 32tph (though doesn't actually run at that, though the not much newer southern half of the circle line does).

i bet you’ve upgraded your rail gauge geometry since original construction.

i’m much less confident that we have. or redone the tunnel layouts, hence all the squealing.

Yep, and the old ones in Hungary work well as well!
