In the case of the Braintree line, when that train stalled between Quincy Center and Quincy Adams, the power was eventually cut so it could be evacuated (after people had been on the train for 2+ hours). They lost the line then, as the third rail became covered even more than it already was. The Ashmont line and the southern end of the Orange Line were reopened using plow trains (both conventional trains with plow-equipped trucks and the plow-equipped crane cars being pushed by a six-car consist). They tried to reopen Braintree with a plow train with the crane car, but they encountered a broken third rail near Wollaston and had to cut power again. Then it was time to bring out the prisoners with shovels and the contractors with excavating equipment.
