Commercial jets are typically pressurized to 7,000 feet inside, with the Boeing 787 somewhat lower (about 5,000 feet).

Airliners are actually usually pressurized to 7,500-8,000 feet, while the 787 is pressurized to 6,000 feet.

Just a thought about the NYP tunnels...would the pressure changes not be good there either?

You might find this useful:

which also advises to use caution when shipping potato chips as well.

 

Not mentioned so far is taking the Empire Builder from Chicago to Seattle, and the Coast Starlight down to LA. This would be similar to the Sunset Ltd. routing from an elevation perspective, the highest points being the Marias Pass in Montana at 5200'.

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.

A word of warning, my grandpa has a breathing problem as well and took the Sunset Limited LA to Houston (and back) with his CPAP. He still suffered pretty badly on the trip. Even though it's not super high elevation, it's still pretty prolonged exposure to higher altitudes. My Grandparents discovered that the prolonged exposure was worse on him than the short exposures to high altitudes that flights give.

If I won the lottery, I'd probably build a passenger from nowhere to nowhere.

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.

The Sunset has the lowest elevation to the west coast but as Bretton88 mentioned, you still have pockets of high altitude. The highest is close to 4,600 feet. There are other areas where the train is 3000+ and 4000+ feet above sea level.

Surely being from Brooklyn you've ridden through those tunnels and you know the sudden pressure change is very noticeable.

Just another bit of elevation info regarding the Sunset Limited, the route is actually below sea level while running along Southern California's Salton Sea. This is usually during darkness for both #1 and #2.

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.

Great idea!  Here's the Amtrak info page on that:
