Why are we doing all of these closures?
We know CTrain closures can have an impact on your travel, which is why we try to keep them as minimally disruptive as possible. That’s also why they’re so important - because doing preventative work and maintenance now can ensure we’re providing Calgarians with a safe, reliable, and efficient transit system.
Some work can be completed while keeping the trains on track, but there are certain projects that are just too big, or can’t share the space safely while trains are in service, and they require fully closing off sections of the line. Occasionally, a power cut is required to carry out specific work, which also means we need to close the line to train travel.
During the planning stage, we try to consolidate projects where can to minimize how often we need to close a certain section of the system, and do our best to plan around major events or times of heaviest transit use. Wherever possible, we will opt for single tracking instead, to further reduce impact to service.
What is “single tracking”?
When considering the work that needs to be done at (or between) specific stations, we’ll look into whether closing just one side of the tracks is a safe, effective, and available option. Also known as “single tracking”, this type of closure allows us to complete the important work while also keeping train traffic moving!
Trains travelling in either direction will share the same track and same side of the station/platform.
So, when this happens, keep an eye on the station’s digital displays, and an ear out for the PA announcements to make sure you’re in the right spot - and don’t forget to double check the train’s destination display before hopping on!
