A Tokyo subway company and the Tokyo Fire Department conducted a special earthquake and fire drill Wednesday, following last week's fatal subway torching in South Korea.

The evacuation and rescue exercise was based on the premise that a large number of people had been injured when a quake resulted in a fire, power outage and derailment on a section of underground track between Kinshicho and Oshiage stations on the Hanzomon Line.

The drill was carried out by the Teito Rapid Transit Authority (Eidan) and the Tokyo Fire Department.

Originally, a straightforward earthquake exercise had been planned in preparation for the March 19 opening of a section of line between Oshiage and Suitengumae stations, Eidan officials said.

Some 100 firefighters and 12 firetrucks, as well as subway personnel, took part in the drill.

The Feb. 18 subway fire in Taegu, South Korea, killed at least 133 people. It was started by a man allegedly bent on suicide.

Police said Monday they arrested seven subway officials on suspicion of negligence.
