I feel like hearing myself talk, and I have a soapbox sitting here, so here goes.. feel free to ignore me.
I am a locomotive engineer for Norfolk Southern. I've been one for over 6 years, and was a conductor before that. all told, I've been there over 13 years now. I am a model railroader, and have been most of my life - ever since Christmas when I was 2 and I got a Lionel train set. Call it 30 years, more or less. I've been an HO modeler since I was about 10, and have dabbled in everything from HOn3 redwood logging and freelance Rio Grande-esque Colorado NG, to scratch building in Fn3, to On30, to standard gauge modern era, and now to Southern Ry. steam/transition era - first a freelanced what-if extension of the Tallulah Falls RR connecting with the Murphy Branch, and now to the Danville & Western Ry., a short line owned by Southern, ca. 1940 (with occasional excursions a decade or more in either direction).
Working for the railroad changed my modeling. I quickly lost any interest in modern era stuff. I also became much more conscious of scale, detail, operation, and sound. When you are hanging on the side of a box car shoving several miles down the main line, you become rather intimately familiar with the grab irons. When you learn to tell how a locomotive is running by the sound it's making, or to brace yourself when you hear the slack coming, or jump when you hear the brakes go into emergency, chintzy, tinny, generic sounds become grating to the ear. When you spend your days switching industries, operation takes on an entirely new feel.
But why would I want a hobby that is just an extension of my job? I get that a lot, especially at work. My first answer is that it's not at all like my job. For one thing, I can walk away, or drink a beer while I play. For another, I do not model modern era NS, so the rolling stock and operation are different. I do model a line I work on today, because I have taken a keen interest in the history of all the territory I cover. My second answer is that when I go home and run a train, it is MY world. I can fix all the stupidity I see all day at work, and I get to have it the way a railroad should be (in my mind, at least). My third answer (which I rarely get to) is that I enjoy my job. A lot. I am doing what I have dreamed of since I was a toddler. How many people get to say that? Of course, they still have to pay me, and frankly it's not the dream job that I dreamed of. I could go on for hours with the problems at NS, but that's a personal thing (and might get me in trouble at work, too!). Still, I enjoy switching cars, running trains, watching trains go by.
The other thing is, I have loves outside of work and family. I like building things. I love anything steam powered. Plumbing is slightly erotic to me. Machines fascinate me. I enjoy history, and research. If I had the time, money, skill, and tools (someday..) I would be building live steam in 7.5" gauge. Until then, I can enjoy building an intricately detailed scale model of a steam locomotive that I have spent years researching, and then watch it pull a train around a layout that I built based on the history of the railroad.
What railroading has done is to drive out any interest in modern railroading or the business side of things. I just cannot get excited about that new NS ES44DC on your layout. It's ugly, and I despise the prototype. Sounds good, though; but your N scale model sounds like a tinny toy version - that thing can RUMBLE! I also cannot get off on switch lists, car cards, train orders, waybills, brake tests, or any of the other many and varied forms of paperwork that I have to put up with at work every day. If I'm working a local on your layout, all I want to know is what cars should be spotted where, and what cars need to be pulled. I don't care what we're pretending they're loaded with, I don't care where they're supposedly going, so please don't ask me to keep up with all that. I will work with and tolerate your fast clock, but I don't really see the point. Aren't we supposed to be relaxing and having a good time here?
I have come to the conclusion that most model railroaders really wish they were working for the railroad. They try to make the experience as realistic as possible, right down to the frustration of having to re-rail a car using a crane. To them, it's as close as they will ever get to the real thing. I respect that, but I am trying to get away from the real thing, so I tend to look at things a little differently. I want to take what I like, and eliminate all the things I don't. I think that some people (see another thread..) get so wrapped up in simulating the railroad that they simulate themselves right into a cranky mood at having to deal with the hassles, but without the benefit of getting paid to be there.
What does all this mean? Nothing. I told you, I just like to hear myself talk. I would like to know if other railroaders have similar opinions and experiences, though. I would also like to hear from the folks that have to use period-correct paperwork for everything they do. Does it make the hobby more fun, or just more difficult? Does it serve any real purpose (like keeping track of where you put that box car that really needs a new coupler on the B end), or is it just something else to do?
Maybe I'm looking at it wrong. Maybe I'm more of a model builder than a model railroader, and railroading has made me want to do a little operation with the models that I build. Maybe if I hadn't gone to work for NS I might not have a layout at all, just a giant workbench with models of whatever strikes my fancy. Maybe that's the part I don't understand - that operation to me is a useful purpose for a model, whereas to some people it IS the purpose, and the models are just the pieces needed to make it happen.
