CTrain

The CTrain, officially Calgary C-Train, is a light rail transit system in Calgary, Alberta, Canada. It is operated by Calgary Transit, a division of the City of Calgary, and consists of two lines commonly referred to as the Red Line and the Blue Line. The network serves central Calgary and extends to surrounding suburbs, providing rapid transit that complements the city's bus system.

The CTrain began operation in 1981 with the initial line and has since expanded through extensions and rolling stock upgrades to form a two-line network that intersects in downtown Calgary. The system includes a mix of at-grade, elevated, and underground sections and aims to minimize street-level conflicts through grade-separated alignments where possible.

Trains are electric and powered by overhead lines on standard-gauge track, employing centralized signaling and train-control systems to manage service and safety. The rolling stock consists of modern low-floor light rail vehicles designed for accessible boarding and reliable daily operation. Stations offer amenities such as real-time arrival information and fare integration with Calgary Transit's overall system.

Ridership has grown with the city’s expansion, and service frequency varies to meet peak and off-peak demand. Park-and-ride facilities at select stations help connect suburban residents to downtown employment and amenities. The CTrain is a central element of Calgary’s public transit network and continues to be modernized through fleet renewals and signaling upgrades, with ongoing plans for future expansions to accommodate growing demand.
