Have you ever seen a rules test? This test from the Erie Railroad, dated 1930, was given to new firemen and trainmen who were on the job for six months.
This exam is 38 pages and contains 324 questions, covering train operations, signal aspects, whistle signals, etc. Tests like this are still given by railroads today.
I couldn’t resist acquiring this interesting piece of railroading. I do have an Erie rule book from this same period that I have skimmed through over the years.
I took this test and had no problem answering over half of the questions. I have to review to get the others. Oh well, looks like summer school for me.
