A driverless transport system in Tokyo is back in service four days after one of its trains derailed due to Thursday's earthquake in the Japanese capital.
The Nippori-Toneri Liner -- an automated guideway transit system -- resumed operation from the first scheduled train on Monday morning.
The operator, the Tokyo Metropolitan Government, says service during the busy hours of 7 a.m. to 10 a.m. had to be scaled back by about 10 percent as some cars were damaged by the quake.
It says Nippori and other stations were almost as crowded as usual. The line runs through Adachi and Arakawa wards in northeastern Tokyo for about 10 kilometers.
A commuter says she used other lines the day after the quake to get to work, and she's glad the trains are running again.
A couple who use the system to go to hospital say they were wondering if they should use other lines or buses if the suspension continued for a long time, so they are grateful that the service has resumed.
