Basic Dimensions for 'Shoe Box' and 'Tilt-up' Factories etc

[FCIN]

I'm basing the warehouse on my ISL on known door size and spacing dimensions of a facility here in town that I used to work in my railroad days. The case house at the Old Grandad distillery. It was constructed in the mid-50's with 10ft x 10ft doors on 70ft centers. All the cars we spotted there were 50ft box cars, but most of them had extended cushion underframes, such as Hydroframe 60, making the car length just a bit more than 60ft. So when cars were spotted, you had a nice little spacing between each of them. Cars with end of car cushioning would have more space between them. It looks great on a model railroad layout when the cars are spotted at individual doors and there is some open space between them and typical of what you see at many such facilities.
