A MBTA maintenance vehicle rolled off the Red Line tracks in Dorchester Sunday evening, crashing onto Elm St.

The Boston Globe reports, the person operating the machine was taken to a local hospital for evaluation. T spokesperson Joe Pesaturo told the Globe the operator was “using the equipment to spread ballast on the rails.”

Boston Fire responded to Elm St around 6:30 p.m.. According CBS Boston, “the crash caused hydraulic fluid to leak out of the machine.”

Ballast, the substance being scattered across the tracks at the time of the incident,  is crushed rock used to support railroad ties.

The state Department of Environmental Protection, CBS Boston reports, was called in to determine if there was any potential impact on the surrounding environment. If the fluid spilled on soil, it could potentially seep through the soil into the groundwater.

The cause of the accident wasn’t immediately determined, but an investigation is underway. At this time, the operator has not been identified.

Due to previously scheduled Red Line track maintenance, shuttle buses between JFK/Umass and North Quincy Stations were already in place.

The T was scheduled to resume regular Red Line train service Monday morning.
