The trains should only run on tracks that are completely enclosed (More control on the environment will realize better reliability, and as an aside nicer living space. Raised tracks are ugly.), Also they should run on rubber wheels like the Montreal metro has since 1966.
Both metros should have barrier between platforms and tracks since they know where the doors will open. It's sad but a non-negligible cause of delays are due to people jumping on the tracks.
