So I'm looking to model a fictional Cement Works and possibly a Limestone Quarry somewhere between 1948 and 1968 (only in Trainz for now, as I don't have the space nor budget), but I have very little knowledge of how these would actually work in operations. In the little bit of research I've managed so far there's actually a lot more to making cement than I realized! If I'm correct, Limestone is a prominent ingredient, hence why my Cement Works shares facilities with a Limestone Quarry. If this incorrect however, I'll most likely scrap any plans for the quarry. I will probably end up redressing the route to represent the workings at different points in time; my "history" is that it was originally opened in the early 1850s and served as one of the motivations for the opening of the (fictitious) local railway. So my main questions are:
1) What kind of commodities would the Cement Works (and quarry) need delivered to the site? Would this definitely change in the hundred years since opening, or is it possible that this site could still be using the same recipe? And also, what type of industries does it come from?
2) What commodities do they ship out? This seems obvious at first: Cement, in both bulk via presflos and pallets of individual bags of cement via box vans. The Limestone Quarry may also export, well... limestone, depending on the exact relationship between the two. I imagine they are both managed by the same company, though the quarry may be a subsidiary. But there is also the mater of waste. When they're done mining their limestone, and mixing their cement, what's left over that they have to get rid of? Where does it go?
3) What types of rolling stock are these commodities transported in? At least in the cases that aren't obvious (I'm not that clueless)!
Thank you for any assistance!
