I have a small 2x10 shelf railroad under construction. A small brewery complex is planned for one end along the backdrop.
I was planning on having a warehouse for outbound loads of beer - room for two or three insulated box cars. Then on an adjacent track I would have an unloading area for convered hoppers, with pipes going up and into the building, and probably a tank car unloading platform for receiving whatever liquids/syrups are required. The hopper car and tank cars would be unloaded on the same track (two different spots), figuring they would require less switching than the outbound finished product.
We have a wonderful brewery here in Bend, OR - Deschutes Brewery, with a large presence on the west coast at least - and I know a few people that work there I could hit up for details. Too bad they don't have rail access, but I can always adapt what they receive in trucks to rail.
