Historically, express bus stops are denoted with a red sign, but the use has been abandoned since 2000 in favor of a unified scheme.
Calgary Transit's BRT routes has very few features of a modern bus rapid transit system, with limited stop service and signal priority being implemented (originally, the use of articulated buses was also a feature, but the use has spread to some high-volume local express routes).
BRT in Calgary is meant to be a placeholder for soon-to-be-constructed LRT routes.
Service from Calgary International Airport on Route 300 uses 2013-2014 New Flyers fitted with luggage racks at the front of the bus.
On Nov 19, 2018, Calgary Transit introduced 3 new MAX routes.
