I once saw a suggestion that railway hobbies tended to appeal to men of the cloth because of the many similarities between railway operations and a cleric's day job. At least, railway operations as they were up until a couple of generations.
I can't give a reference to where I saw that idea (or fully recall the details) but a minute or two of thought suggests similarities like:-
- Both railways and the established church are governed by a large, thick Rule Book, which specifies indisputable instructions on how most things in day-to-day life shall or shall not be done.
- Other subordinate texts then followed on (General Appendix, New Testament*, Book of Common Prayer, Sectional Appendices and Local Instructions).
- Relevant and important clauses from the voluminous Rule Book had to be committed to memory and able to be recited, chapter and verse. One may be tested on these periodically.
- Some of the rules and regulations in the big, thick Rule Book are archaic and outdated with little relevance to modern life but remain because 'it has always been done like that'.
- In reality, certain rules & regulations were quietly adjusted or ignored to pragmatically allow for 'local operating conditions'.
- There was a definite, clearly defined hierarchy, with associated costumes. But on a day-to-day basis many operatives worked entirely on their own initiative without direct supervision by their line management. However, somewhere unseen, there was always the presence of an all-knowing, all-powerful authority known as Control.
- Maverick individuals with their own opinions and ideas of how things should operate were not welcomed by the hierarchy.
- Sometimes, if you were lucky, it was an easy, relaxing job with nothing much happening for long periods (if you believe TV dramas, incumbents of rural parishes often had time to help various police inspectors solve mysterious murders). But there was a well-established timetable for when you knew you'd need to be on top form (Sunday Communion / Mass, or arrival of the London Express).
- It could be tricky to get a foot in the door at first and knowing someone on the inside or having a 'face that fits' can help getting the plum jobs. But once in, you were in for life, unless you do something especially catastrophic. Even then, the organisation might have made some attempt to cover up on your behalf, largely to cover its own ar*e.
