A Boston-bound MBTA commuter rail train from Kingston experienced a mechanical malfunction during the Thursday morning commute, causing smoke in the engine and prompting an evacuation of all aboard in Hanson.

In an email, Lisa Battiston, a spokeswoman for the state Department of Transportation, said the issue was reported by train crews around 6:45 a.m.

“A turbocharger malfunctioned, causing some engine lube oil to be exposed to extremely high temperatures, which caused smoke conditions,” she said. “At no time was there any risk to passengers or employees. With safety as a top priority, the fire department was on scene as a precautionary measure.”

Hanson police said as of 8:12 a.m. evacuated passengers were being transferred to another train.

Photos and videos on social media showed crowds of passengers waiting on the train platform and smoke billowing from the locomotive’s engine.
