Another day of project on time for 7 at GPK? Is it still the holiday hangover?
When the temperature is over 91 degrees, the maximum authorized speed drops to 60 MPH from 79 MPH.Could you clarify what a heat restriction is? Thanks!!
Yep. I believe they lowered it last year because the tracks were in such bad shape.Actually, last year BNSF started these restrictions at 85 degrees.
:-(
The heat restriction is not put in place at the same temperature everywhere. The number will be higher on much of the Southwest Chief route because the high/low/average temeratures are higher. Heat restriction is for the purpose of reducing the force the train applies to the track laterally as at higher temperatures the rails are in compression which gives them a tendency to shift sideways when pushed by the back and forth forces of the trains. These forces happen even on straight track because the world is not perfect.Actually, last year BNSF started these restrictions at 85 degrees.

And no extenuating circumstances this time. Too bad because it had been doing reasonably well. Westbound the EB has been doing fairly well.#8 in MN now over 7 hours behind--a brutally slow run thru ND today.
