The Montreal STM Metro was forced to evacuate three separate stations last night.\n\nIt was not a great night for the public transport network, with the presence of smoke and faulty electrical equipment causing service interruptions.\nHere's what we know. 👇\nVisit MTLBlog for more headlines.\nIf you were riding the Montreal STM metro last night and experience and shutdown, you likely weren't alone.\nAnd I don't mean the other passengers who were with you on the train or platform with you as you waited, wondering what's up. I mean across the city last night Montrealers were dealing with disruptions to the metro service.\nIn fact, it seems there were two separate instances of stations almost needing to be evacuated last night, one on the Blue line and one on the Orange line.\nAdd to that the fact that, momentarily, trains were no longer stopping at Viau station on the Green line and we've got ourselves three metro lines all going haywire within the window of an hour or two.\nI did reach out to the STM to see if these instances were, in fact, related, but their response seems to imply that the incidents were separate and it all just kinda went down in succession.\nEverything seems to have begun with the initial diverting of trains past Viau station on the green line.\nNo trains stopping GREEN line at Viau station. #stminfo C— Ligne Verte (@stm_Verte) September 24, 2019\nService normal du métro #stminfo Q— Ligne Verte (@stm_Verte) September 24, 2019\nBonjour, le service a été interrompu à la station Viau en raison d'un dégagement de fumée à proximité de la station, mais le service est maintenant rétabli à cette station. Merci!— Ligne Verte (@stm_Verte) September 24, 2019\nWhich was eventually explained by the STM, as being caused by the presence of smoke from a fire that was actually outside the station and had managed to seep its way inside.\nThe tweet above reads:\nHi, service was interrupted at Viau Station due to a smoke release near the station, but service is now restored at this station. Thank you!\nTrains began letting passengers on and off fat Viau again after no more than 20 minutes, perhaps even less... so it seems unlikely that this could have had anything to do with what happened next.\nREAD ALSO: How Montreal Streets Got Their Names\nAt around 9:30, nearly an hour after the Green line experienced its own delay, it was the Blue line's turn.\nA mother tweeted at the STM asking why there was an evacuation at Snowdon station, because her daughter had contacted her to let her mom know what was going on.\nIl y a eu un ralentissement de service un peu plus tôt (vers 21h25) sur la ligne Orange en raison d'un problème d'équipement, et à un certain moment, un train à la station Snowdon a été évacué puisqu'une interruption du service métro se préparait - (1/2)— STM (@stminfo) September 24, 2019\nThe STM responded:\nThere was slowdown earlier (around 9:25 p.m.) on the Orange line due to an equipment problem, and at some point a train at Snowdown Station was evacuated as a metro service was being prepared.\nPar contre, le problème ayant été résolu, la préparation à l’interruption de service a été annulée, et les clients ont pu réintégrer le train quelques minutes plus tard. Il est possible que cette évacuation du train ait pu causer confusion cela dit - (2/2)— STM (@stminfo) September 24, 2019\nThey continued:\nHowever, the problem was solved, the preparation for the interruption of service was cancelled, and the customers were able to re-enter the train a few minutes later. It is possible that this evacuation of the train could cause confusion.\nThe mother made a point of telling the STM that their message was evidently not clear enough, because her daughter evacuated the station (as she assumed the message on the speaker had told her to) and didn't know that service had resumed. She was then left to walk home, in the dark, in a neighbourhood she didn't know.\nOver on the Orange line closer to downtown, another issue arose, this time at Bonaventure station, when it seemed the same issue was at hand.\nThe tweets below are in response to questions about the Orange line and Bonaventure station in particular, where there was another evacuation.\nHello, there was a service slowdown due to an equipment problem, but regular service is now gradually resuming, thank you!— Ligne Orange (@stm_Orange) September 24, 2019\nHello, there was a service slowdown due to an equipment problem around 9:25 p.m., and a train was evacuated at Bonaventure station as we were preparing to maybe interrupt service - (1/2)— Ligne Orange (@stm_Orange) September 24, 2019\nbut the incident was resolved, service resumed, and it was possible to get back on the train a few minutes later. Thank you! - (2/2)— Ligne Orange (@stm_Orange) September 24, 2019\nIt also seems that, again, the message requesting evacuation was not clear in specifying if passengers were required to leave the station or simply the train car.\nThe STM let me know that the source of the issues on the Orange line stemmed from faulty electrical equipment at Lucien L'Allier station.\nThey believed that the interruption was going to last longer than it did, so in preparation for needing space to turn trains around, they evacuated Snowdon and Bonaventure.\nIn the end, service resumed far quicker than anticipated and the evacuations were momentary.\n@stminfo were the almost-evacuations at Snowdon and Bonaventure related to the stopping of trains at Viau station last night? Or were all three instances totally separate? I'm always curious how issues on one line can/may impact the rest in the network. Merci!— Lena Slanisky (@lvbs) September 24, 2019\nI reached out to ask the STM if these incidents were related and received a response by e-mail that did not implicate any connection between the incidents that all went down between 8:30 and 9:30 p.m. last night.\nMysterious.\nHeard a metro code you've never heard before?
