Earlier this month on the Washington DC Metro, one woman died, and at least 84 others were injured when a Metro car filled with smoke. According to one news report, subway riders were escorted off the train through a tunnel, but not before dozens were exposed to the dangerous smoke.
Evidently, the incident occurred near the L’Enfant Plaza station at around 3:30 in the afternoon. One witness told reporters that suddenly smoke started pouring in from between the doors, filling the cabin in seconds. He went on to tell reporters that, while some of the passengers were fine, others started to react quickly and severely to the smoke in the cabin.
The cause of the smoke remains unknown, but it is assumed that it was nothing more than a fire and not any act of terrorism or other criminal act. Regardless, for the family of the one woman who died, and the many others who were seriously injured, the exact cause of the accident is not what is immediately important.
