My post of OM going east early on March 5 is in error, as I offered in my posting correction this date. My initial posting times indicated AM and they should show PM.
As far as train 116 being late on March 5. Train 115 of March 4 (remember, the one waiting at Osier) had a derailment at Pagosa Jct (Mar 4) and this added to the late arrival time in Durango.
