As I remember, the Cardinal once ran with Superliners, so Superliners can fit in the Capital Street tunnel.
That means if Amtrak rebuilds the Baltimore tunnels to Superliner clearance, are there any other height restrictions to prevent a Newark NJ AutoTrain? Platforms wouldn't be an issue since it would be using it's own dedicated station. There is a ton of land near Marion Reach and South Kearny yard that could be used for parking.
Assuming the Fredrick Douglas Tunnel will be built to handle Superliners and double-stack freight (24 feet from rail to caternary)... you have to clear (from WAS up to Newark)...

...and THEN the Fredrick Douglas Tunnel as planned.
You also have to clear the catenary, and I forget our previous conversations about that in other threads about how close that caternary can be w/o affecting people inside. All the cars are 16' 2" from what I can tell, and the minimum IMO would be 18' tall caternary... but I'd be more comfortable with 24' tall caternary.
There is one other consideration: are you going to go diesel all the way up? Because I doubt a train that long and that heavy is going to hit 100 MPH on the NEC... or anywhere period.
