The cars are pretty nice. These aren't the cars we will be getting, initially, for the Sugarhouse line. The company that produces these is based in Portland and they are just taking them around to a few cities in the country showing what American made transit vehicles look like. The cars are currently 70% American made, and with a new propulsion system that this exact car will be getting they will be 90% American made. This actual car will return to Portland and be used in its Street Car system.
The cars are more nimble than light rail, allow for better movement through traffic and tighter turns, they articulate in two spots. The middle section is platform height on entry and the the ends have three stairs at the entry(like trax).
I should have taken a couple of shots inside. Sorry!
