New buses are arriving on site daily and will hit the roads within the next few weeks. The 500 series of buses, which include the fleet used to provide the Bishop Ranch commuter service, is being replaced with new 40-ft. low floor vehicles. Immediately following is the 200 fleet of buses. In all 33 buses are being replaced. By the time most vehicles are replaced they’ve travelled over 400,000 miles in tough stop-and-go commuter traffic.
