The monorail service connecting Tokyo's Haneda airport to the downtown area was temporarily suspended Tuesday following a power outage, canceling 75 trains and affecting close to 16,000 people.

Tokyo Monorail Co. said a six-car train stopped around 2:15 p.m. between Showajima and Seibijo stations, stranding about 40 passengers. At around 3:30 p.m., a second train pulled up alongside the stopped train for passengers to cross over. No one was injured.

A malfunction in a substation caused the outage, stopping service in both directions for about two and a half hours, the operator said.

Buses were laid on to transport passengers to the airport and those with train delay certificates were given seats on later flights by Japan Airlines and All Nippon Airways.

The Tokyo Monorail Line connects Haneda airport and Hamamatsucho Station, which is served by two JR lines.
