Work on escalators
Investing in our escalators
With a constant view to improving your transit rides, we are set to refurbish and/or replace 63 sets of escalators in the métro network. Work will begin in June 2016.
An escalator running upwards should be available at all times, whenever possible, in an effort to facilitate your transit experience while work is underway.
24 new escalators
Seven métro stations will be equipped with the new escalators. The older ones being replaced were chosen because of their age and the structural work needed to support the new escalators. Work in these stations should be kept to a minimum. Some of the escalators at Saint-Michel, Édouard-Montpetit, Jean-Talon, Namur, Côte-des-Neiges, de la Savane and Fabre stations will also have been replaced.
Work is made possible thanks to funding from the Ministry of Transport, Sustainable Mobility and Transportation Electrification and by Infrastructure Canada as part of the Canada-Québec Building Fund.
Major refurbishment of 39 escalators
These escalators will undergo a major refurbish, using a combination of new and reconditioned spare parts. These escalators were chosen because of their 30-year average age. Some escalators inside Côte-Vertu, Jean-Talon, Outremont, Acadie, De Castelnau, Fabre, D’Iberville, Bonaventure and McGill stations will bee refurbished
Work is carried out thanks to funding provided by the Ministry of Transportation, Sustainable Mobility and Transportation Electrification.

- Service to resume : Fall 2018
- Type of work : replacement of escalator
- Escalators : leading from Côte-Vertu platform to Snowdon train platform: the one next to the wall will be replaced first, followed by the next one in September.
- Alternative route : two other escalators located nearby will remain operational while work on the first two are underway.
- Service to resume : Summer 2018.
The escalator is now operational, but is still being monitored. During this period, we may have to stop it once in a while for adjustments.
The project will help improve the reliability and efficiency of escalators.
Extracting the existing escalator
- Dismantling and removing over 1500 parts, including anywhere from 74 to 154 individual steps, without damaging surrounding structures.
- Salvaging all reusable parts.
Laying the groundwork
- Reinforcing the structure, if required, as the new escalators are heavier.
- Moving some conduits.
Installing the new escalator
Manipulating large, heavy parts that must be precisely positioned in tight spaces.
Assembling and adjusting all parts
- Precise assembly work (the escalator must be straight along its full length)
- Mechanical adjustments (brakes, tension of pull chains, etc.)
- Programming adjustments (vitesse de veille, etc.)
Performing qualification tests
- Rigorous testing
- One month period of operation without passengers to confirm performance of each new model and ensure compliance with strictest safety standards
Final approval for operations
Most of the escalators in the underground system were replaced over the past few years. However, there are still some sixty escalators that date back to the métro’s expansion in the 70s and 80s. And when they break down, repairing them is rather more complicated. Spare parts are harder to obtain, causing further delays. This unfortunate situation currently prevails in a few stations, where getting the escalators up and running is a long time coming.
The reasons behind escalator shutdowns
Incidents involving improper use are the main reason why escalators are out of service. For example, items are dropped and get stuck in the stairs or people fall down, requiring the escalators be stopped. Improper use by people, like sitting on the moving handrail or pressing the emergency stop button for no good reason, is also a frequent cause.
Maintenance crews on the job
If an incident has little or no repercussion on an escalator, it can be started up again quickly by a station employee. On the other hand, if there is any chance the incident has damaged or otherwise compromised the escalator’s integrity, the equipment must be shut down until specialized mechanics can inspect it and perform any necessary repairs or adjustments before putting it back into service.
The STM’s underground system holds 296 escalators and with 250 million passenger trips through the métro each year, these units are subjected to heavy use. Furthermore, several escalators are located next to entryways, exposing them to harsh weather conditions and temperature changes
Maintenance staff is not always visible, because much of the action takes place….below! Customers only get the see the stairs, whereas all other components, including the motor, are located underneath the stairs.
No, they are subject to preventive maintenance and are regularly inspected.
