Police in Hanson said Main Street along Route 27 was closed at the station, with a disabled train blocking the street.
Keolis, the company that runs the commuter rail, blamed the incident on an electrical short, saying it "produced some smoke in the locomotive cab."
"In compliance with safety protocols, train dispatch reached out to local first responders to manage the vehicle traffic in the area and ensure there was no risk of fire due to the electrical failure," a Keolis spokesperson told NBC10 Boston in a statement.
A firefighters union in Hanson said earlier crews were dealing with a train fire at the Hanson station, noting that the train had been evacuated and asking people to avoid the area.
The Hanson Fire Department's official Twitter account had not shared any information as of around 5:20 p.m.
