En Route to Pittsburgh, PA. I had to change buses in DC to get to Pittsburgh (and had to do the same thing to get back to Richmond), and I got a VanHool both times. I'll admit that these buses don't ride too bad. This is a VanHool Model C2045 with a Catepillar C-13 engine and Allison B500 transmission. "Jake Brakes" are active. CORRECTION (04-25/2011): This bus has a CUMMINS ISX engine, not a Catepillar C-13 engine as I originally thought. I had a chance to confirm this (by sight) today.
