SEATTLE -- About 190 people were evacuated from the Seattle monorail's red train after it stalled Saturday afternoon near the intersection of 5th Avenue and Lenora Street.

The train slowed to a stop about 4 p.m., and firefighters had to wait for electricity to be turned off before raising ladders to the train cars above 5th Avenue.

Seattle Fire Department Deputy Chief Steve Oleson said no one was injured, and the train stopped when lost power while heading heading to Westlake Center.

The red train just resumed operation August 10 after being idle for a week due to an electrical flaw in its power system.

By 4:30 p.m., firefighters had started the process of evacuating people down ladders, and at 4:45 p.m., the blue train pulled alongside to offload the remaining passengers still stuck on the red train.

The blue train has been undergoing renovations and tests, and was not making regular runs with passengers.

Standing barefoot below the monorail line after being evacuated down a fire department ladder, 11-year-old Kamrin Mara said she probably wouldn't be riding the monorail again.

"They didn't want us to go down in our flip-flops because they said it could be dangerous," she said. "It got really hot in there, it was just scary because I didn't know how we were going to get down."

Firefighter propped open doors for airflow and brought up bottled water to thirsty passengers.

Everyone had been safely removed from the train by about 5:15 p.m.

Monorail officials said Saturday night that a faulty pneumatic valve was to blame for the train losing power.

The part was replaced and the train thoroughly tested, officials said, and service was expected to resume Sunday morning.

The one-mile line between the Seattle Center and Westlake Center was built for the 1962 World's Fair, and is still a big tourist attraction. It has carried about two million passengers a year.

But the monorail line, which has carried about two million passengers a year, has been plagued with problems in recent years.

On May 31, 2004, a fire broke out on the blue train near the Seattle Center, trapping 150 passengers inside until they could be rescued. Eight passengers and a firefighter were treated for smoke inhalation .

The fire was blamed on a failed drive shaft that caused a series of electrical shorts and arcing that ignited the undercarriage.

On November 26, 2005, the blue and red trains sideswiped each other on a curve near the Westlake Center station. No one was seriously injured, but dozens of passengers had to be evacuated by firefighters, and the trains were out of service for months.

The trains have been taken out of service several times since for repairs and overhauls.
