Twin-aisle passenger cars?

Is there such thing as a twin asile train car (such as an airplane going oversea's might) and, if so, where? Is there any chance that any passenger railroads may purchase some? It would be very interesting to see a "extra wide" train set going down the main line.

There are no extra-wide trainsets. 10' is just about max for train running on 4' something rail.

Can't run anything wider because tracks are too close together. Tunnels are also too narrow. Platforms would also be in the way.

Track gauge is 4 feet 8½ inches in width. Widest passenger cars I'm aware of on FRA tracks are the Amfleet cars, at 10 feet 6 inches.

Does "upstairs/downstairs" count, for two aisles? Bilevels have 2 aisles, like an Airbus, or 747. Answers already provided, for multi-aisles, same floor level.

Funny you should ask. As I understand it, Airbus has decided that since its Superjumbo A380 can't get into the air, it will convert all of them to rail cars. Even though Airbus has absolutely zero experience building rail cars and every single railroad consultant has advised that the new "rail"planes will not fit throught the Hudson Tunnel, NJT has signed on to buy 250 of them.

Didn't the IC have 5 accross seating with asiles on the sides by the wall, at one time, years ago?

Might as well...

Two outer aisles would leave room for three seats (not economical), or four tight ones.

Back when the Erie was a 6' gauge, they marketed their wide passenger cars. Anyone know how wide they were?
