While I have not been there yet, I believe this is the coordinates to the overpass that collapsed.
If it is, it is the highway between Scott City and Chaffee (I was born in Chaffee when they had a hospital as a side note).
Event recorder data from the locomotives of both trains, as well as recorded data from the signal system, is being examined to determine train speeds and signal aspects prior to the collision. Initial data review indicates that the UP train was traveling about 49 mph when it struck the side of the BNSF train, which was traveling about 22 mph.
Preliminary data indicates that the BNSF train received a signal indication permitting it to proceed through the interlocking, while the UP train received a stop signal indication at the interlocking. No positive train control system is currently installed at this location.
