Yeah. I was out earlier today and I looked more carefully to see if there were any variations. But since my observations, I am convinced that they were merely modifications made to the original cars. Frankly, I'm still puzzled as to what they're called. I just know that they're manufactured by Kinki Sharyo. I am interested to see what the Siemens S70s will look like, as they have several different visual differences between the variants out there (between Minneapolis, San Diego, Houston, Charlotte, Portland, Salt Lake City, Edmonton, and whoever else).
