Re: FRA ''preferred'' replacement Amtrak/MARC Baltimore tunnel now up to $4 billion

Obviously something newer would be faster.

As for height, I've looked into it, and here are the ones of note:
MBTA/MARC Kawasaki BiLevels: 15'6"
LIRR C1/C3 BiLevels: 14'6"
NJT/AMT MultiLevel: 14'6"
Superliner: 16'2"
ATSF HiLevel (Predecessor to Superliner): 15'6"
Bombardier BiLevel (favorite of every commuter RR that does not need high platforms): 15'11"

So, now that I think of it, the Baltimore Tunnel clearance right now wouldn't be a restriction against newer Amtrak bilevel cars. They would just have to fit the MARC profile. The ATSF HiLevels are the precedent for using cars of such height in intercity service.

So assuming gateway's tunnels are built larger (which they would probably be anyway), the last hurdle is the East River, and possibly NYP itself.

It's pretty annoying that one station dictates the rolling stock constraints for half the Amtrak network, even if it is the most important station east of Chicago...
