I'm so used to dependency downloading that I looked for a route to download when I got all the dependencies for a route. I like building industrial routes, but My products are ALWAYS the same. Paper, electric motors, cement, scrap, and pipes. I need to diversify my products. Can someone recommend common commodities?
What kind of operations are you looking for and in what era? Fruit and Veg (Reefers of any description really) were common in EVERY town up till about the 1970's/80s or so when Trucks took over alot of it. To this day in Seattle theres a few huge Food Distribution Warehouses that, if they're not actively using their rails, retain much of if not all of the active Rail connection in case they ever decide to start using them again. United Grocers has one up on the south end of Boeing field. Theres also a smaller one that actively does transload of mostly food from Reefers to Trucks on the North End of Boeing field and it gets supplied with about 5-8 new reefers every other day or so.
On that line of thinking, Flour of various descriptions gets hauled around alot in 2 and 3 bay covered hoppers for Bakeries. Theres a Franz Bakery up here in SODO thats supplied by Rail.
Dirt. Theres a company up here which is actually responsible for being the first commercial customer to cause Rail to be Laid in seattle in over a decade who's entire business model seems to be loading Dirt on and off of barges for I don't even know what purpose. Suffice it to say they do it anyway..... They're getting themselves a nice new 3 track yard which from the plans I've seen should be able to hold about 20 Gondolas or Hoppers of Dirt Fairly effectively....
Fuel Coal and Oil for Heating, as well as for Vehicles has always been a small little industry for the railroads for a long time as well. I know when people think of Coal these days they think about 150 car Unit trains, but back in the day, once it got to somewhere like Cleaveland out of the hills of West Virginia, as often as not there would be lower grade coal sent out in packs of 2-12 cars to various points for distribution to towns as Stove/Fireplace Fuel. That started to die about the 1960's/70's or so. Fuel Oil was the replacement and I think as much of that has been hauled by truck as anything else, but the Railroads have carried some.
Diesel Fuel is one I see alot of being moved around. If you're a coal mine (Or anyone really) out in the boonies, its far easier to have the railroad thats picking up your coal drop a tanker or two of Diesel on a siding for fueling up..... Theres other reasons for inner-city/suburban customers to want this as well (Bulk purchasing usually saves some money for instance), but I haven't personally seen a whole heck of a lot of this around specifically Seattle.
All KINDS of nasty chemicals to choose from. Argon is a big one, but theres also alot of propane floating around (har har). After that, you tend to get 1-4 car loads of almost any chemical you care to name.
On that score, Granulated chemicals, Lime being a HUGE one (This is usually carried in a covered hopper) as its used to make cement, but literally tons of others. Theres certain types of fine sands that carried around for use in all kinds of industries...... The Cement Industry is kind of like a quiet giant. The stuff is everywhere, and most every community from Small Towns to Huge Cities have at least one cement plant of varying size and description (Its rare to get Rotary Kilns outside of the really large facilities though). Almost all of these facilities that are more then about 15 years old or so are, or have been at some point, serviced by Rail. Making Cement eats TONS of certain chemicals and its just wholly ineffective to try to move it all by Truck generally speaking, (There are of course exceptions, but you usually really have to go digging to find them).
Automobiles. About twice a year (Usually beginning and end of summer), I start seeing tons of Auto Carriers coming in and out of Seattle. Im not exactly sure why this industry exhibits this particular pattern, but someone has to carry thousands of Fords, Dodges, Chryslers, Toyotas, and whatever else have you across the nation....
Steel.... You've got Scrap, but what are you doing with it? Steel Mills often take scrap and melt it down and then make Sheet Rolls, Pipe, Rail, Beams, Plate, or just Small Steel Stock out of it. Though its rare for a Steel Mill to *just* do Scrap reclamation (That does happen occasionally), they often also make new steel as well from Coal and Iron, or depending on their business even Coal and Melted down Scrap Iron.....
On that score, Machining Facilities. Take new steel and produce Widgets, or whatever. The more recent you get the less these tend to be serviced by rail, but some that specialize in bigger items still are. Shipyards are a GREAT example of this kind of thing, but there are numerous others.
Lastly Intermodal of any description. Pretty much every major city at this point has some kind of mid-large sized Intermodal Facility. By Intermodal this can take the form of TOFC, or just Containers on Well Cars and the like.
Hope that helps,
