GOODWELL, Okla. (June 25, 2012)--Three Union Pacific crew members were still missing Monday after two trains collided in the Oklahoma Panhandle, causing a white-hot fire that emergency crews struggled extinguish.

Oklahoma Highway Patrol Trooper Betsy Randolph says the fire near Goodwell was contained, but was still burning Monday morning.

A National Safety Transportation Board team was investigating the Sunday morning crash.

Each train carried two crew members, and officials say one conductor survived after jumping off the train.

Three crew members are missing.

Randolph said firefighters from Fort Worth were en route with fire-suppressing foam after hundreds of gallons of water failed to put out the blaze.

After the fire is extinguished, crews must wait for the metal to cool before they can safely search the trains for any sign of the missing crew.
