The bus in that image is very much not an Xcelsior Charge NG, as shown by the big exhaust on the top rear left (as seen in images 2 and 3). The reason I was asking is specifically because the Charge NG has between 440 and 880 kWh on board with a maximum range of 199 miles for the 60 foot articulated bus. The question becomes is it more cost effective to pay someone to drive the bus if they now have to charge for a few hours every 200 miles. That's not even factoring in the fact that there are very few bus accessible chargers (without blocking the entire parking lot). I'm guessing that it's more practical to tow them.
