stress tested

my hub sucked
but yeah you may want to prioritize your bypass lines. you should do another design where the bypass lines don't change in elevation at all, since that seems to massively slow down maglev, at least in relation to their default speed (tunnels for the station lines instead) actually nothing you can really do about it.
edit:
after some slight adjustments, i managed to make it fail more graciously

looks like this time the sheer amount of trains killed it, coupled with the stuffty placeholder signaling outside the main hub. i'm sure on a real line, rather than a stress test, it could probably hold a lot better.
you can steal it if you want.
