PANHANDLE, Texas (AP) — Authorities hope dogs searching the wreckage of two trains that collided last week in a fiery head-on crash in Texas will find the remains of a conductor whose body has yet to be located.

BNSF Railway spokesman Joe Faust said Wednesday that funerals have been held for another conductor and an engineer whose remains were recovered a day after the June 28 wreck in Panhandle, 40 miles northeast of Amarillo.

Authorities have not released the names of the deceased.

Faust says an engineer who jumped from one of the trains ahead of the crash is hospitalized in stable condition.

The rail line reopened July 1. Faust estimated debris cleanup could last three more weeks.

A National Transportation Safety Board spokesman declined comment Wednesday.
