A partial freight train derailment in West Jordan brought nearby TRAX light rail traffic to a crawl during Wednesday morning's commute, but was cleared by noon.

The 3:30 a.m. Wednesday derailment involved the front two engines of a Savage Systems freight train hauling 15 cars, 10 of them empty and five containing tanker loads of isobutane gas. None of the tankers were compromised, but the engines, while upright, were teetering off the rails near 4000 W. 9000 South in West Jordan.

Savage spokeswoman Rebecca Boucher confirmed that no injuries occurred and none of the cars behind the engines had derailed. She said the cause of the accident was under investigation, though company personnel reported were looking at the possibility of a faulty rail switch being a factor.

Light rail traffic — specifically the "Red" line leading to the University of Utah campus — was delayed about 15-20 minutes as trains shared the one remaining rail span to get through the accident scene.

Utah Transit Authority spokesman Remi Barron said that in addition to that, a "bus bridge" was used to ferry commuters around the scene.
