McKenzie in the southeastern portion of the city, finally ending at the South Health Campus in Seton. Phase one of the North Central Line will travel from 16th Ave. north to Shepard, in the SE.

Construction started in 2018 on works to enable future rail construction. On July 18, 2007, Calgary Transit officially unveiled a new red and white livery for its CTrain, articulated buses and every new bus or train coming into the system. On August 27, 2008, a train en route to the Somerset station collided with a construction crane in between the Dalhousie and Brentwood stations. Six were injured in the accident, including one child. On February 18, 2009, Calgary Transit celebrated the 1,000,000,000th rider, randomly selecting a passenger, Shelly Xiao during a ceremony at the 1 Street SW CTrain station. Bus rapid transit On August 30, 2004, Calgary Transit opened a bus rapid transit line to operate future CTrain routes (the D-Line and an as-yet unplanned northbound line), using conventional buses until articulated buses entered service on June 25, 2007. The BRT system consisted of a single route, Route 301, serving the northern and western parts of the city. A subsequent route, Route 305, was added in 2008, serving the Bowness and 17th Avenue East corridors. A third route, Route 302, entered service on August 31, 2009, along a proposed southeast LRT corridor. The BRT is considered to be the successor to the Blue Arrow service introduced to the 1970s: both were a series of limited-stop routes that were to be intended to be replaced by LRT service in the future — however, the Blue Arrow service was never a true BRT (limited stop service, stopping at designated blue bus stop signs, was its only distinctive feature), the modern BRT includes priority at traffic signals, enhanced passenger waiting areas and offers a shorter travel time to the downtown with greater capacity articulated buses. The Blue Arrow name all but disappeared in 2000 in order to unify all bus stops under one common scheme, but certain Blue Arrow routes are still in service to this day. In fact, Route 305 replaces a Blue Arrow route (Route 105). On September 28, 2009, Council approved the Calgary Transportation Plan (CTP), fulfilling Council's priorities
