Where are the Transit Police or any MBTA employees? Thank God the MBTA doesn't have their own fire department like Massport? Great response by the Boston Fire Department.

Not sure what the T Police are expected to do, hell the BFD doesn't even jump on the tracks till they get conformation the power is off and then test it.

I listened in on this but it was Ch 4 so audio wasn't great but it sounded like wires fell on the third rail

The problem is that metal dust build up from the constant passing of steel wheels against steel rails, coupled with natural humidity, builds up a layer of rust and carbon on the 3rd rail insulators. This eventually builds up to a point when conductivity will begin, the carbon and steel dust heats and eventually ignites. If ther eis any trash nearby that can also be an issue. Once an arc of enough voltage is created, the carbon builds up more perpetuating the reaction.
