The STM is introducing a tone to alert passengers before the metro doors close. This is meant to increase efficiency and ensure comfort and safety aboard the metro, presumably by preventing bits of people from being slammed between the doors. Click below to hear the tone:
You can listen to the sound here.
Last fall I wrote about the source of the sound which is unique to Montreal’s metro system, a by-product of the 70s technology. The real dou-dou-dou will eventually be lost when the
19631973-edition metro cars are replaced (although at this rate it won’t be any time soon). I like that there’ve found a way to preserve this familiar little audio experience in its natural habitat.
The STM is looking for feedback so if readers have any relevant comments, I’ll be happy to forward them…
