We measure the on-time system performance of three types of transit services: train, bus and Calgary Transit Access (specialized transit for people with disabilities). We do our best to be on time and minimize delays, however some circumstances beyond our control affect reliability, including inclement weather, road and traffic conditions and passenger emergencies.

Where we're at (CTrain)

CTrain on-time performance

This graph shows the average percent of CTrains that arrive within planned frequency, which is how often we plan for trains to arrive. This is tracked with a geofence, which is a virtual boundary around a CTrain station. When the train enters and exits the boundary, the time is tracked.

Ctrain reliability

Between 2013 and 2015 we had an average of 54 major CTrain delays each year. In 2016 we had 57 major delays. The red line shows how we compare for 2017.

CTrain reliable causes

CTrain delays of 30 minutes or more are caused either by internal or external factors. Examples of external factors include weather, a vehicle blocking the tracks, pedestrian or vehicle contact with trains, and passenger emergencies. Examples of internal factors include mechanical breakdowns and traction power and signal systems failures.

Where we're at (Bus)

Bus on time performance

Bus reliability is measured by the percentage of buses departing major bus stops on time (-1 to +5 minutes).  This is measured by Automatic Vehicle Locators, which are GPS systems on every bus.

Where we're at (Calgary Transit Access)

Reliable Rating

As of 2015, the on-time performance for Calgary Transit Access was 90%. Our target is to reach 91% by 2018. Learn more about Calgary Transit Access' on-time performance.

What we’re working on

We’ve identified the following actions as top priorities for improving reliability:

  • Continue to measure and report bus and train system on-time performance.
  • Continue to upgrade and expand our fleet. Replace older buses, community shuttles and trains.
  • Implement Transit Priority Measures (such as transit-only lanes, signals, etc.) to decrease travel time and improve trip time reliability.
  • Implement escalator and elevator monitoring across the entire system.
  • Provide real-time arrival information to Calgary Transit Access customers. This will allow us to notify customers 5-10 minutes before arrival at their pickup location.

What we’ve done

In 2015 we did the following to improve reliability:

  • Established ways to measure on-time performance of buses and CTrains and began reporting the data here.
  • The first four-car CTrains began operating on the Red Line in November 2015.
  • Calgary Handibus joined Calgary Transit Access.
  • Replaced older buses and improved vehicle maintenance programs, resulting in a significant improvement in the frequency between bus breakdowns.
  • Significant investments were made in CTrain reliability including upgrades to traction power and signal systems, a track switch monitoring pilot, break and motor upgrades, and more.
  • Expanded indoor storage for buses, which keeps buses warm and more reliable during winter.
