Have a look at pretty much any route that Rick Grout (G-TraX) has built or contributed to. Here on RWA that's of course the new freeware release
Maine Maritime (former Portland Terminal) which comes with several large and small industrial buildings and warehouses. Also here on RWA, the (though not freeware) Cascadian and the R&WA Lakeside Route might have what you're looking for.
And if you're aiming for a Workshop release which would rule out using any of the three routes I just mentioned, there's also Stevens Pass, the Racetrack, and the Sacramento Northern where you probably can find several useful models.
And please excuse the unsolicited advice, but if you're unsure whether to release here or on the Workshop, I'd recommend skipping the Workshop and doing it here instead. I've tried both and here you certainly get a better reception and much better feedback. It's just a *nicer* home for your work here. Plus you can use all those nice assets from sources that the Workshop won't accept, like RCAP.
