Santa Clarita / Antelope Valley : 7 Injured at Magic Mountain : Accidents: A roller-coaster is shut down temporarily after a train bangs into another taking on passengers.

Seven people were treated for minor injuries after a weekend accident at Six Flags Magic Mountain in which a slow-moving roller-coaster train banged into another in the loading station, a spokeswoman for the Valencia park said Tuesday.

The Colossus roller-coaster ride was shut down temporarily after the incident at 11 a.m. Sunday while a minor brake adjustment was made and safety tests were conducted, spokeswoman Eileen Harrell said.

The ride was back in operation by early Sunday afternoon, she said.

Harrell said the Colossus, a 15-year-old roller-coaster with tracks built on a wood framework, has numerous brake systems that slow the ride and stop it at various points on the tracks. As a train carrying 24 passengers was pulling into the loading station at the end of a ride Sunday, the final brake did not bring it to a complete stop, Harrell said. It hit another train with 24 other passengers waiting to start their ride.

“The last brake didn’t slow it enough,” Harrell said. “It was probably only going 1 mile per hour and it bumped into the car ahead.

“Nobody was really hurt,” Harrell added. “We sent some people to the hospital as a precaution.”

The names of those riders were unavailable. Los Angeles County Fire Department logs list the injuries as minor and a spokeswoman for Henry Mayo Newhall Memorial Hospital in Valencia said all the riders were treated and released.

“Most if not all of the patients had neck and back strain,” hospital spokeswoman Cathleen Lee said.

Harrell said that after an adjustment was made to the brake system of the roller-coaster, park crews ran several tests on the ride before reopening it.

“They stopped the ride until they made sure everything was OK,” Harrell said. “We have a standard procedure that we follow to check our rides.”

Harrell said no other review of the accident is anticipated. A sheriff’s official said the department did not take a report on the incident.
