My D&RGW Timetables. I am missing '61.
We rode the Royal Gorge in '60, '61, '62, '63 and '64. The train was truncated in '65 losing the Dome and ending the run in Salida so we skipped it.
Tin the 1960 Timetable there is a "90" notation in my Dad's handwriting in the margin between Grand Junction and Fruita. That meant, of course, 90mph.
