Yesterday I caught a glimpse of Montreal's new metro cars going through testing. I was at Station Berri-UQAM on the way home when a weird horn sounded from one end of the tunnel and then this seek silver bullet popped out. Half the people on the platform took out their smartphones and took photos of it while it stopped.
I had read that STM [our transit agency] was testing the new cars out without picking up passengers, so I didn't line up to enter the train. However, plenty of people peeked inside. The cars are not furnished yet, but rather filled with bags of rocks to simulate the weight of furnishings and passengers.
The new train started moving again a couple seconds later, and the real train nonchalantly pulled up two minutes later. From what I understand, the new cars will be phased in very gradually starting next year. The new cars are expected to last a half-century or more thanks to a fully-enclosed tunnel system that places a check on corrosion and vandalism.
I've never had a problem with the current cars. They have the same cute sky-blue exterior from their debut 50 years ago, and while the interiors are dated compared to the latest metro systems [my experiences in China come to mind], they're far cleaner and more civil than the NYC Subway. Plus, they've got retro flair.
