24/7 does raise the bar a bit, but if you have three tunnels not two per line, the problem isn't all that bad. NY has three tunnels as far as I'm aware. In contrast, London's underground has only two which makes it rather difficult to do maintenance at the same time as operate a line.
Digging new tunnels should mostly be independent of operations in existing tunnels.
- ethanbond 10y agoSure but there are times when the lines aren't operating, which is a more crucial point than whether there are three tracks (which is not the case across all of NYC).
- iamatworknow 10y ago>NY has three tunnels as far as I'm aware. Only in some areas, mostly in Manhattan. The outer boroughs, especially in areas where the tracks are elevated, usually only have two. When major track work has to be done the MTA has a habit of just shutting down a line temporarily. For the past couple of years they've been shutting down the 7 train (which goes from 34th street through Times Square in Manhattan to Flushing in Queens) multiple weekends during the summer, and it has had an impact on businesses.
