@Platinum107 4 u:
actually i saw this notice and was already planning to go see this, they should be doing this tomorrow and Friday as well if anyone is interested. When i stopped by, the train was stationary, with the diesel locomotive coupled to it. The train looks complete, except for no pantograph, and some very technical-looking fringy things attached to the front to measure clearances (i assume). So, I didn't get any videos of it moving, but here's some photos.




One thing that really struck me, seeing this thing out 'in the wild' was just how low these things are. There's maaaaybe 6" of clearance between the bottom of the car and the track, and the doors are just a few inches above that. the train is just as low, if not lower, than a bendy bus. in this pic, you can just barely see the wheels peaking out:
I guess that's another point about these trains, relevant to the street running they will be doing: although they are big, carrying slightly more people than a single U2 car, they are lower and thinner, and the streamlined nose lightens the visual weight a lot as well. They are also surprisingly long; again rationally we know this from technical stats, but seeing it in person, you don't really connect both ends together, you kind of expect there to be a coupling somewhere in those 7 sections. these are a different beast from what we run currently on the high-floor lines. I'm excited to see them running on their own power at some point.
