queston about storage tracks......

[geepers]

hello everyone, im wondering how or what determines if an industry needs a single line in to unload, or two lines in to it? i have been reading John Armstrongs book( Realistic track planning), but im not sure what justifies a single or double track into an industry. anyone have any ideas or recomendations? the industry in queston is the Walthers golden valley cannery. thanks everyone!

It's a function of carloads per day. An automotive plant needs ten to twenty tracks to load cars. A cannery would probably need a large number of cars and loading locations in season and none at other times. Canneries are pretty small for the most part and I doubt they would produce the need for more tha two cars per day in season so I would use one track.
