A tram derailed in downtown Oslo and plowed¹ into a phone and computer shop on Tuesday, Norwegian police said, but the accident only left four people lightly injured.

There were about 20 people on the commuter² train when it derailed off the tracks at an intersection³ on Storgata, one of the Norwegian capital’s main thoroughfares close to Oslo’s main train station.

Images from the scene show that most of the first carriage of the tram had slammed into the shop. Police and the fire department said the crash had caused extensive damage in the shop.

The tram driver was among those injured. Police said everyone was treated at the scene but no one had serious injuries.

Operator Sporveien runs the trams and the subway in Oslo. It says the tram system carries about 50 million passengers a year.
