Hair-raiser tale about this very tunnel

I knew a gent named Harold Eidson who worked on the ATSF during the Second World War. He was a great story teller-he was disqualified from the armed forces 12-7-41 when he was blown off the deck of the USS Pennsylvania (it was in dry-dock) at Pearl Harbor. He was sent home, and hired on the ATSF out of Gallup. He said train crews were young (4-F)kids and "codgers" held over from retirement. He caught a number of trips with an engineer that hired on the Atlantic and Pacific in 1892! He started every trip with "medicated" coffee (1/5 coffee and 4/5 bourbon). One westbound trip this engineer highballed a red block as they entered this tunnel. He saw a marker lamp shining at the other end! He ran over and slammed the brake valve into emergency, stoppimg only three car length from the caboose! Boy,was that old-timer p.o.ed about some upstart fireman making that decision for him! It turned out the engineer passed the flagman. It was WWII, and what would get people fired today was swept under the rug, since help was very hard to get! Well, this steep grade was a bottleneck on the ATSF and it was replaced by a massive relocation in 1962.
