Yes, there were some really hateful railroaders not that long ago. Everything -- everything, including actual skills and rules knowledge -- was on-the-job training. After five student trips (unpaid) I had to spend three years as a Fireman in order to have enough road service (yard service didn't count) to be eligible for promotion to Engineer. Two Engineers, in particular never spoke to me (or any other Fireman with less than ten years of experience) whenever I worked with them, except to ask for my pocket stamp for the time slip. Another, when we tied up for rest in Los Angeles, told me what restaurant he ate in and that he expected me to eat in a different one. Most, though, were congenial, and a few were genuinely friendly and showed me useful things. Many of the Engineers would allow the Fireman to run the engine half of the time, if the Fireman was presentable in his habits and showed some interest. I saw Yard Foremen who followed inexperienced Helpers (Yard Conductors and Brakemen to you who are from the east) criticizing them non-stop, in the most demeaning terms. The only way those poor Helpers could get it to stop was to get better at railroading skills.
And, in the steam era, it was worse. Some mean old Engineers would intentionally beat the Fireman out of steam and then criticize him. The Air Brake Supervisor who gave me my Air Brake oral examination for promotion engaged me in conversation later and revealed that the first time he had ever run a train on the main line was after he was a promoted Engineer. That was in 1943. No train handling experience at all before his first paid trip as an Engineer!
Nowadays, the railroad gives training classes first, instead of sending new Brakemen out into the jaws of mean old men. And there are only a few grouches out there today, because, when you have a two man crew, you have to get along with, and depend on, each other. Most crew members are congenial and much more humble than the little kings of the past.
