How the T could have improved its response to this morning's Red Line accident

Although the man/train accident was at Park Street, commuters elsewhere on the line report the same sort of chaos that broke out there. In a letter to T officials, Goose details what happened at Downtown Crossing:

The Red Line train I was on was stopped about 20 yards short of the platform at Downtown Crossing. We were held there without light or ventilation for 20 minutes. Why wasn't the train moved to the platform before shutting off the power? Any additional emergency that might have occurred on stopped trains would have compounded the crisis. ...

Other problems the T should fix: Non-functioning PA systems, inadequate crowd control and a blocked off Park Street (which meant problems for the shuttle buses that were supposed to ferry riders around Park Street).
