In the South

...a building may have a curve on the side facing the tracks, but they were always squared off on the other sides of the buildings...

Russ, you are right. There is no prototype in Vernon for a "banana building". The building became more prototypical with a straight wall but is was to massive and dominated to much. I learned that I may show the front of "large" building in the rear of the layout but must place smaller buildings in the foreground.
I did follow fast car's example on the left side and broke the building into three smaller units. That works fine and one building follows the curved track.
Another observation is the difference in the optical appearance of free space in Vernon. All top/bird view show a dense development. That changes drastically if you switch to street view. There is a lot of space not occupied with buildings. Some space are parking lots, some are fenced areas and some are the very typical areas of "nothing" to be found in the US so often. Another unique feature of Vernon are the sidewalks. That unusual for an industrial area and I missed them in the beginning. I have started to implement them as lots become new populated.
ps. It is funny to see how the sidewalks have been carefully planned and how thankful they are taken to populate them with all kind of utility poles etc. until they are totally blocked
