What good is biodiesel without a bus to use it in? Below is a picture of the UR Biodiesel bus. The bus began operation on Earth Day, April 22nd, 2009. It runs primarily on the Green Line (pun intended) that transports students to local shopping centers. The bus also occasionally subs in on the other bus lines. Finally, the bus is very popular for charters, and groups often specially request the biodiesel bus for their events. If you would like to use the UR biodiesel bus at your event, email Andrea Walton in UR Transportation at awalton@parking.rochester.edu to make a charter request.
