9:02 on channel 5 John Gill Deputy Superintendent Boston EMS reported 40 transported from Government center and 6 from Park Street.

I was on a D line train heading toward Brookline Village last week and the driver was texting on her cell phone the entire time. I wonder what we will find out is the cause of this accident. Happy to hear no one was seriously injured this time.

Any sort of train or trolley under ground is very, very dangerous.

They should all be replaced with busses running in special lanes on the street. They could paint each bus silver. Silver painted = faster! And the street, they could paint that green! Green paint = other cars won't drive there!
