“Fun” fact, the rules were metaphorically written and blood, and grew to include things like “don’t microwave your clothes to dry them”.

Everyone who had worked in the rail industry (especially conductors and engineers) for more than a few years has horrible stories. PTSD is real. Suited by train is fucking selfish and disgusting.
