This is a good subject. When I was retiring from the Carpenters Union, I was seriously looking into getting a job with SEPTA or Amtrak. In my research, I was told by others, in the business and not in the business, that I would be very disappointed once hired. They claimed I would get the worse assignments, etc. I was 57 at the time.
From time to time, I have regretted not pushing forward with it. Of course, at my age now, 70, it's probably out of the question.
But I would also like to hear what it's really like from those who are in the business.
