I assume your looking at the lead car, and this will be the shape of the new lead cars in Salt Lake. The cars pictured above are simply the main body. It's all the same as this picture below, just the different color scheme.
I agree that the streetcar should be the choice for the East Bench. Also, Highland has a much better existing setup for it than Van Winkle. Highland would develop into a very attractive corridor with the addition of a streetcar system. The addition of more attractive residential lowrise/midrises, and 9th/9th style village cores along Highland Dr. from Sugarhouse to.....hey, even continuing through Union Park and beyond makes perfect sense to me.
I'm really getting jazzed about more and more trolleys coming to the metro. I would love to see some systems alla 'Euro style' like those we recently reviewed, in Bordeaux, France and eleswhere.
