Calgary Transit currently runs over 160 bus routes, of which 86 are designated as "low access", and are accessible for those who need a wheelchair to move around. Calgary uses buses from four companies; Nova Bus, New Flyer Industries, General Motors Diesel Division and Motor Coach Industries. In 2004, Calgary Transit started a bus rapid transit service along future C-Train routes. The bus rapid transit routes have less stops than other routes, and use articulated buses as of 2007.
