Mr Z,
Interesting comment on the tourist railroad. As I may have mentioned, I was an engineer on the C and O in the 1970s all the while attending college. After graduation, other employment opportunities ensued.
I worked mainly in yards on switching crews, imagine that, or on locals with trains to other yards or industries.
Our local runs were at lower speeds than road crews but I still had many close calls at road crossings. Fortunately, no accidents. I still remember standing up pulling on the whistle chord, as if to make it louder, for near collisions with automobiles. It’s hard to believe what people would do avoid waiting at railroad crossings.
Omg, in the space of a few years I had a Winnebago pull out in front my train one time, and another time was coming uphill into a grade crossing with the safeties popping off and the whistle screaming and at the last second a car ran in front of me so close the rear corner of the auto had to have been in the space between the front of the coupler and the pilot beam. ( The car came from the opposite side of the cab. The fireman and brakeman riding along had called all clear. As I was getting into the crossing the guys started shouting. Since I had one hand the whistle, the other killed the throttle. By the time I got my hand to the brake to try to slow down it was pretty much over as the car had emerged across the front of the engine and was exiting the crossing. And I was not not slow with my hands! I ended up barely touching the brakes and rolling through the crossing. The passengers never knew how close it was.)
When backing up we had a conductor on the rear with a full size rr headlight, air horn and an emergency brake. As we got close to a crossing at night one time I remember hearing " four cars to crossings, crossing clear all right back.", Soon the horn would start sounding and in between the first and second blast I heard " Two cars to crossing, crossing clear, alright back." The horn would continue and the I heard the same thing for 1 car to crossing, and 1/2 car.
The last horn was longer than usual.
The next radio transmission I heard was " That guy had brown hair, brown eyes, and an earring." Apparently the car dashed in front as we were entering the crossing, too fast for the conductor to dump the air anyway.
Unbelievably, I never actually had an accident. There are some things I don't miss.
