A cider press, ships cider and apples.
A gunpowder works, recieves nitrates, sulphur and charcoal, ships gunpowder.
A coal yard, recieves coal and lumber
Several freight houses and team tracks
Why do I have those industries? Because they were on my chosen railroad in 1900, my chosen era Based on my research, most of the industries will even have the “correct” names (FM Brown and Sons, Harlan and Hollinsworth, Dyer Quarry, Super Phosphate, Lukens Steel, E.I. Dupont, etc). I found the industries by looking at old maps, finding shippers guides, looking at history books, reading railroad magazines (those produced by the railroads themselves) and researching the companies and processes themselves.
I will have several more (another foundry or two, furniture factory/wagon works, coal yards, lumber yards, feed mills, another quarry, etc) that I haven’t firmed up the plans yet, all of which will be based on actual industries or at least typical of the area.
In addition, I will have a lead that will represent the line to a car ferry that will run to another explosives and chemical plant (Pigeon Pt., DE to Carney’s Pt., NJ, also on the prototype) and at least 3 interchanges (B&O, PRR).
