Why does a hyperloop fit in a smaller tunnel than a train? Doesn’t it need to do everything a train does, plus it’s wrapped in a vacuum tube?

As far as I understand, the original proposal relies on a) no safety egress walkways in the tunnel and b) a more cramped vehicle profile.

I don't know how as-actually-built hyperloop compares to rail tunnels.
