So, is this going to be an 8-car test train?

That what I thought at first until someone in another forum said he recalled that the first set would remain in Nebraska as reference during production.

Okay, that make sense. So I'm going to assume this will be a four car Train. I know the 7000s are going to be like an A-B-A-B|A-B-A-B set.

In the strictest sense they are not A-B+A-B or A-B+B-A sets as various subsystem are shared across all of the cars in the 4 cars of the set.

Like their married pair cousins they share various subsystem across both cars in the set. They are more like A-C+C-B. The A car has one group of subsystems, the B car has another group of subsystems and the C car has a third group of subsystems. All of the subsystems must be present to allow operation in revenue service.

This does complicate matters somewhat in that an A-C+C-A set can not be operated in revenue service because it lacks the subsystems of a B car, the same would apply to a B-C+C-B set.

This is why they can not be coupled into 6 car revenue trains.

You know, I never understood why train cars are arranged like that.

Very simple, cost. It is far cheaper to spread the various subsystems across multiple cars then it is to pack all of them in each car. No need to put a hotel power inverter in each car if the same one can provide hotel power for 2 cars. No need to put an air compressor to pump up the brake reservoir in each car if one can pump up the reservoirs in more then one car. No need to put the various subsystem needed for automatic train control in each car if you never intend to operate single car trains. One of the reasons why WMATA went with "married quad" was to eliminate the costs related to maintaining the redundant cabs and the various subsystems need to support it, they also did it to increase passenger capacity.

And these are also 75 foot cars right?

Yes. The dimension. (width, height and length) is the same as the existing rolling stock. The reason why is because all of the maintenance infrastructure in the shops (servicing bays, lifts, hoists, turntables for removing trucks and inspection pits) is configured for married pairs with 75' long cars.

According to the above Associated Press story it will be more then just a photo opp, it will also be a "ceremonial first ride".

I would love to be there for this one.

WMATA might leave them at the platform for a while for the public to see after the dignitaries have left to get out of the cold.
