the whole metro tunnel concept is at once too small and too big and it makes me sad that it's not as revolutionary as it could be.
Like you'd think it would unlock a ton of capacity in the city loop but apparently not, and there are other things in the system preventing significant frequency improvements.. Not to mention the people who lost a direct link to the sportsball grounds..

Imagine if they could have gotten some more lines through the metro tunnel such that the city loop can be fully bidirectional or something
