"Parking lots take up a lot of real estate, and all of mine are about 50% too small. In fact, I seriously doubt a real car could put into one of those parking spots without hitting anything. It's the curse of O'scale."
Ain't that the truth. On a prior layout I thought I had allocated an ample amount of space for parking around my passenger station. After a few minutes playing with cars on it I realized it just wasn't going to work as I planned. Fortunately after continuing to play with the cars for a few days I was able to find a parking layout that was somewhat plausible. (Rumors that I was making car noises while doing this are wildly exaggerated.) If I had done this before I might have laid it out differently. Chances are that most people who will look at your layout won't notice these things...but you will.
