CALGARY - Twin teenage brothers who died during an after-hours visit to a luge-bobsled track were remembered Sunday as dynamic members of their school communities, while prayers continued for other boys who were hurt in the crash.

Jordan and Evan Caldwell, 17, were killed and six other male teens were injured early Saturday while using a personal sled/toboggan to go down the bobsled track at Canada Olympic Park.

Their sled hit a large gate used to separate the luge and bobsled tracks.

Jordan Caldwell attended Westmount Charter School, where the student newspaper described him in a profile online several months ago as "an iconic Westmount personality."

The article, by Grade 11 student Sravya Kakumanu, noted Caldwell was "a persuasive debater, passionate Model UN diplomat, strong mock lawyer, spirited student president, and an energetic tubaist."

Evan Caldwell also attended the Calgary school with his brother from Grade 5 to Grade 11, but switched to Ernest Manning High School last year in order to take pre-engineering classes, according to a statement from the Caldwell family.

The brothers both got straight-As and helped homeowners affected by the 2013 flood in Calgary, the family said. Jordan taught himself to unicycle. Evan played guitar and taught English songs to arriving Syrian refugees.

"Our boys Jordan & Evan were bright lights to all who knew them. We are grieving their loss but confident in their new home of heaven. Our brief 17 years with them were a gift: filled with much love, laughter, and fond memories," read a statement from Jason, Shauna and Katie Caldwell.

Both boys attended church at Rocky Mountain Calvary Chapel, where Pastor Quinn Davis said two other boys who were injured in the accident also attended.

Davis said one of the boys, Caleb Hettinga, had been in critical condition but was stable on Sunday afternoon after undergoing surgery. Another boy, David Carr, received stitches and was recovering, Davis said.

Davis said a team of pastors is with the affected families.

"Because this is a Bible-believing, Bible-teaching Christian church, we have a great hope. We are sad and we mourn, but not as those who have no hope," Davis said, describing the mood of the congregation during Sunday's service.

"We all believe in our fellowship that one day we'll again reunited with these young men."

WinSport, which owns and operates Canada Olympic Park, said Sunday that both the boys who died worked as "Hill Ambassadors" at the facility last season.

Their family said they welcomed guests at the base of the hill, scanning tickets and helping out.

WinSport president and CEO Barry Heck told reporters late Saturday that as a father himself his heart goes out to the families.

He said the organization is co-operating with police and supplying CCTV footage to help determine how and why it happened.

"The loss of Jordan and Evan Caldwell is being felt by many in the Calgary community, including our team here at WinSport," a news release from the organization states, noting it has set up memorials at the hill.

"We have sought out support for affected team members to help them through this very difficult time."

Heck said WinSport is also going to conduct its own review but doesn't think there's a problem with a lack of security on the track.

"We have robust security measures throughout the park and again safety is extremely important. We have a full time security staff that we employ and when the investigation is concluded we will better understand what happened," said Heck.
