Speaking of wastes of time -

I was at the NY Ave metro station last night around 10:45 and had to wait 25 minutes for a Shady Grove bound train. I get it - it's late - but 25 minutes between trains? Just a bit crazy if you ask me. And once a train did finally come, it was only 6 cars and was 3/4 full already!

Why does Metro continue to run 6 car trains? EVER? There is ZERO cost to adding 2 more cars and you add another 25% capacity to each train!

Dumb.

Does anyone know why Metro doesn't run 8-car trains ALL the time? Beyond mechanical difficulties (leading to less cars being available for service) I can't think of any reason why 6-car trains run anymore. With delays clogging stations and cars already packed like sardines, I'd like to see Metro simply run more cars!
