Testing for the Mark V train is now underway during the day, alongside regular service!

During testing, which starts on Mar. 8, trains will stop at stations. If you see the train during your commute, stay clear of the doors and do not board as it’s not quite ready for riding yet.

This is a major step forward in ensuring the safety and reliability of these new cars. It’s the final stage of testing before the train enters service.

Engineers are assessing the train’s onboard systems, performance on the Expo and Millennium Lines, and station upgrades made to accommodate the Mark V’s longer, five-car design.

Daytime testing will happen intermittently throughout the week during non-peak times and won’t impact regular SkyTrain service. All new trains must pass this field testing and meet all safety requirements before entering service.

Trains advance to this testing stage after completing testing at our Operations and Maintenance Centre, near Edmonds Station, and overnight on the SkyTrain tracks when trains aren’t operating.

Field testing will continue as we roll out all 235 Mark V cars by 2029. These longer, Mark V trains offer increased capacity, improved seating, and enhanced amenities for customers.

Mark V features

• New seating arrangement with wider aisles
• Flex areas for customers with mobility devices, strollers, bicycles, and luggage
• The return of the “driver’s seat” at the front and back of each train
• Improved in-train displays and door indicators
• Upgraded heating, ventilation, and cooling systems for improved climate control

We’re wrapping up station upgrades as part of the SkyTrain Expansion Program, to accommodate the longer Mark V trains before they can enter service. We expect to complete train testing and infrastructure upgrades in the coming months, with the first Mark V train to be ready to enter service this spring.
