In the future I will be posting digitized Authorities for Expenditure like this one, most of which have been copied from Colorado Railroad Museum collections by Jerry Day. These are invaluable in pinning down dates that locomotives, cars, structures and tracks were constructed or scrapped.
DENVER & RIO GRANDE WESTERN
Authority for Expenditure No. 6557
Location: Thistle, Utah (Joint Utah Railway)
Date to be Started: April 1965
Date Completed: May 1965
Retire 840 Track Feet of Track No. 104 Rv. Including two turnouts.
Purpose and Necessity:
This trackage should be retired since the coaling facilities previously retired
and new sanding facilities recently constructed have made it no longer necessary
for Railroad purposes.
