Orange Line delayed by a bit of smoke; not enough to make riders choke

There was smoke and a strong smell in the DTX station, and a number of people on the edge of the platform looking to see what the source was. As usual, no communication from the T. Someone must have gone to find someone of authority because one of the volunteers was walking with a walkie-talkie along the platform, telling people to get away from the edge, but providing no further info. Finally a train came in with it's front door open and a T employee standing there probably looking for the source of the smoke. Just another day on the T.
