CAMBRIDGE - The Green Line train that derailed at the beginning of October was going 36 mph in a 10 mph zone, the National Transportation Safety Board Says.

The preliminary investigation by the NTSB showed that the train had left Lechmere Station heading east when it entered a 10 mph zone while traveling at 36 mph.

It then passed through a "double red signal" which requires trains to stop near Red Bridge interlocking, which is where the Medford/Tufts and Union Square branch intersect. The train then drove over a track switch, that was in the process of changing, and caused the second car to head in a different direction from the first, according to the NTSB.

The train remained upright throughout the derailment.
