I drove that section of 66 several times in the '50s, and nothing got your attentiopn faster than meeting an approaching train in the middle of the night: you thought it was on the highway comming at you, a huge one eyed monster rushing at you at 60 mph, then passing you in a rush of steam and clanging of rods. You really took notice of it and your whereabouts. Ah, those long ago years of my youth!
