Vehicle weight is 92,150 lbs; length is 89 ft; width is 8.5 ft. 76 seats. Not run as a single car as they are not ADA accessible, so will always be coupled to a Type 2 or Type 3.

What kind of wheel arrangements do the cars have? Which of the axles are motored?
In all 4 types of cars, the A- and B-trucks are powered (the ones by the cabs) and the C-truck (the ones in the center) are unpowered. Here are figures of the trucks of a Type 3, the trucks in the other types of cars are similar enough. The top one is a power truck (A & B), and the bottom one is an unpowered truck (C)
