司法 · カルガリーのバス安全カルガリー、天然ガスバス347台を維持 死亡事故を受け安全性を見直し執筆 2026年10月18日 1:17 UTC視聴文字起こし0:07Three passengers died after a collision ignited a transit bus's natural gas tanks.0:12Calgary Transit is reviewing safety while keeping its natural gas buses in the0:15fleet.0:16Passengers and drivers are waiting to learn what caused the ignition and whether0:20that review will bring new protections.0:21Calgary Transit says its 347 compressed natural gas buses will remain in the fleet0:26during the investigation.0:27The agency's review will examine its operations and decide whether additional safety0:31measures are needed for passengers and drivers.0:34The agency says its buses receive regular maintenance and safety checks.0:37Those checks were already part of its operations before the crash.0:41The review could lead to further measures, but Calgary Transit hasn't announced a0:45new fleet-wide safety requirement.0:47The collision happened in the 800 block of Saddletown Circle Northeast in Calgary.0:52A city bus was traveling northbound at about 1.10 in the afternoon on Thursday,0:56October 15th.0:57Police responded shortly afterward.0:59The collision reportedly involved eight vehicles, including two city buses and a1:02truck.1:03The two buses use different fuels, and their roles in the chain of events are1:06central to the investigation.1:07The diesel-powered bus struck a truck.1:09then struck a second transit bus.1:11That second bus used compressed natural gas.1:14Its tanks ignited, producing an explosion and a large fire.1:18All three people killed were passengers aboard that second bus.1:21Police are investigating whether speed, impairment, distraction, or a medical1:25emergency contributed to the first collision.1:27They also need to determine why the second bus's fuel system ignited.1:31Finding the cause of the collision and finding the ignition mechanism will require1:34separate work.1:35The first bus's driver suffered life-altering injuries.1:38The injury toll ranges from 16 to 19, and nobody has explained the difference.1:43The total of 16 includes an injured police officer.1:46Police initially counted at least 10 injured on October 15th.1:50Their early descriptions included one person with serious injuries and an officer1:54with minor injuries.1:55Those were preliminary figures as emergency crews dealt with the aftermath.1:59Police later confirmed that the third passenger who died had been identified and2:03their next of kin notified.2:05The traffic section continued investigating the collision after confirming the three2:09fatalities.2:10The tank ignition gives investigators a specific part of the bus to examine.2:14They'll need to work through how the fuel system behaved during the collision and2:17fire, including whether the bus's design or condition contributed.2:21Fire investigator Kevin Weddick of Ken West Fire Investigations said the fire2:26appeared to spread rapidly.2:28Investigators will need to examine the fuel lines and bus design, along with2:31maintenance records and any recent work on the vehicle.2:34Weddick's observation describes how the fire appeared to develop.2:38A technical reconstruction still has to explain what happened inside the fuel2:42system.2:42The Transit Union says finding the reason for the ignition is critical to passenger2:46and driver safety.2:47Calgary Transit's latest statement gives 347 natural gas buses.2:53Its undated website lists 246 40-foot natural gas buses and projects about 3992:59by 2027.3:00Without a date for the website's count, those figures can't tell us how the fleet3:03changed.3:04That webpage also puts natural gas buses at about 20% of the fleet, but its undated3:09figures don't establish today's share.3:11Weddick's earlier estimate of at least 70 buses was expressly tentative.3:14The agency's later statement supplies the more specific fleet count.3:18Calgary Transit is keeping the buses available while it reviews whether more3:21protection is needed.3:22Police still have to explain the first collision, and investigators still have to3:26explain the tank ignition.3:28No completion date has been announced for either investigation or the operational3:31review.記事を読むストーリーの時系列HeyDexショート動画 ↗誰が何を報じたか複数のメディアが報じた論点Number of people killed in the
