Blommer is one of my favorite factories because it is in such a unique position. First, it\'s the only industry I have ever seen that is served by two different divisions of the same railroad on two different levels. The upper level spur that receives granulated sugar is located on the Illinois Division, and the street-level spur for cocoa beans is on the Wisconsin division--at right angles to each other, no less! Plus, where else do you pass freight cars spotted at factories just before disappearing inside of a major passenger terminal?
Sounds like you\'ve got a good chance to take some modeler\'s license if you want (as I did)--just to avoid building North Western Station. Folks here are always interested in nitpicking....er, commenting....on others\' work so we\'d love to follow your progress.
Some of the Walthers N scale kits include water towers, like American Hardware. Some of the modular kits like Empire Leather include water towers, but I couldn\'t find them separately in the on-line catalog. I had extra parts for a wooden water tower, and I wrapped it with thin styrene and added bands of styrene strip to make it look like a metal water tower. Little things like that will help stretch the few kits you can get your hands on.
Let us know how things work out.
