BOSTON — The MBTA released surveillance video of last month's derailment on the Red Line on Friday.
In the video, you can see sparks fly as the train approaches the JFK/UMass station. The train then jumps up and down, before more sparks fly. Seconds later the train slams into several bungalows containing signal control systems.

A second video shows the crash from the viewpoint of passengers on the platform.
At least 60 people were on board the train at the time. There were no serious injuries reported.
The crash caused extensive damage to control signals in the area and has caused delays for commuters since June 11th.
The MBTA says signal repairs between the Broadway and JFK/UMass stations will be finished by August 15th.
When that happens, the average travel time between Braintree and South Station will improve by five minutes. Repairs on the rest of the Braintree and Ashmont branches will continue until at least Labor Day.

Red Line service has been disrupted since the train derailment on June 11th.
The video is part of the investigation into why the derailment happened; it also provides some insight into the damage done.
The train traveled about 1,800 feet before coming to a stop near where the platform begins. The impact of the derailment tore apart several signal bungalows that store electrical equipment.
And nearly six weeks later, the repairs continue – and so do the delays.
"They're running a bit later than usual," said Justin Binns of Boston.
Some signals and switches are still being controlled manually as repairs continue, which is causing some of the delays.

"You have to wait three minutes at each station before it goes, and it's frustrating because I work at a lab so I have a lot of timed experiments so sometimes I’m late to it," said Israa El Sauei.
The MBTA has not released details on what caused the derailment. They have said they do not believe any foul play was involved, and they have ruled out operator error.
They also say the tracks were in good condition, pointing to an issue with the train car itself.
"I have to go out of my way to take an earlier bus to get to the train station, so I leave like two hours earlier instead of an hour early, so I’m really frustrated," El Sauei said. "I'm exhausted from it, but hopefully everything will be back to normal."
