Question about C Trains that is better fit in here; something I thought of when the budget discussion came up.
With the trains, do all 3 cars do the work of pulling and braking? Or does the lead car do all the pulling? (I would assume they all brake.) I ask because of the talk of the franken-car; if the middle car doesn't do much I would think there might be a way to put the older cars in the middle. However seeing that you typically only see similar vintage cars together, they might all share the work. (And the different vintage of cars use different power; right? Older run on DC and newer run on AC through an inverter?)
