2 Madrid subway workers die

Two employees of Madrid's subway system died Monday when a maintenance car they were working on was hit by a cargo carriage, a company spokesman said.

The incident happened around 3 a.m (0100 GMT) when a cargo wagon without a driver rolled out of a city subway station and collided with the maintenance car some two kilometers (one mile) down the tracks.

The two killed were electricians and were working on track cables at the time. Two other workers were treated for injuries.

The subway system was closed to passenger traffic when the accident occurred.

Metro Madrid was investigating the cause of the accident, reports the AP.
