I'm assuming you mean multilevels
(NJT and AMT run multilevels, GO and Caltrain, etc. run bilevels)
They are supposed to hold:
- 127 for the cab cars
- 142 for the trailer cars
- 132 for the trailer cars with restrooms
For comparison, Comet Vs are supposed to hold 109-117 people.
I do believe when the Multilevels were out NJT said they were supposed to hold 20% more people.
The ends if the car aren't exactly wasted space they are flip down seats for bikes and wheelcahirs and also have the restrooms on cars with them.
And yes, fares have gotten quite expensive, but a bus ride on Martz Trailways is hovering around $40 for a one way
trip to New York from the Mt Pocono area. I don't want to know how expensive the train will be.
