What era and geographic location are you modeling? A produce warehouse served by both rail and trucks would have at least one loading dock with multiple doors. It would also have some sort of mechanical refrigeration unit either on the roof or next to the building. A lot of produce is kept out in an open dock in boxes under air conditioning, but some has to be kept under refrigeration. I'm not sure about the 1930's - 1950's, but they might have had tracks next to the dock on one side and a truck dock on the opposite side. By the time the interstate highway system was completed, most produce shipping had shifted to trucks, and the tracks would be on the same side as the trucks, but seldom if ever used.
If it is a produce warehouse, there are a number of names you could use. Before I retired last year, some of the produce companies whose refrigeration equipment I worked on here in Los Angeles were, Coast Produce, G & G Produce, G & G was bought by Sysco and the name changed to Fresh Point of California, a trucking company whose reefers I worked on was named Cornucopia( I'm sure you can guess what their logo looked like) & Borg Produce. There is now a small institutional food distribution company I do work for on a part time basis named Newport Farms. There is also a company named L A Produce, I think. You could name it for the town it is in, for you if you ever wanted to own a business, or for a friend or family member, if you want to honor them. The only names I wouldn't use are the generic cartoon names like Acme or Ajax. It seems to me that every produce company I did work for had some sort of reason for the name chosen.
