Surely being from Brooklyn you've ridden through those tunnels and you know the sudden pressure change is very noticeable.It might not be ideal, but he'll only be on the tunnels for a little bit, and though I don't know the actual altitude and pressure of the North River Tunnels, it can't be much more than 203 ft (the maximum depth of the Hudson River), which isn't very significant compared to the 5000 or so foot Paisano Pass. I do wonder what can be worse for a collapsed lung - higher pressure or lower pressure, which might also be a factor here.Just a thought about the NYP tunnels...would the pressure changes not be good there either?
It's noticeable, but it's not too bad. As I said, you're only in the tunnels for a very short period of time, so I imagine prolonged relatively high altitude would be more of a concern than that. That said, I know absolutely nothing about collapsed lungs, so I'm likely talking nonsense.Surely being from Brooklyn you've ridden through those tunnels and you know the sudden pressure change is very noticeable.It might not be ideal, but he'll only be on the tunnels for a little bit, and though I don't know the actual altitude and pressure of the North River Tunnels, it can't be much more than 203 ft (the maximum depth of the Hudson River), which isn't very significant compared to the 5000 or so foot Paisano Pass.

Great idea! Here's the Amtrak info page on that:I read somewhere that Marias Pass is lowest crossing of the Rockies. Perhaps renting a personal oxygen concentrator might help. I travel with one when I fly.
