Says who? (Other than Larry.)
The ultimate in space-saving is to omit the industry entirely. After all, you'll switch it the same with or without a building adjacent. Put the spurs parallel to the edge of the layout. Instead of modeling a building flat calling it a building not!
While I created a "Godzilla" with the elevator it must stay has it has become one of my favorites besides I like those Intermountain CSX 4650 3 bay covered hoppers.
I thought about using it on my industrial park modules at the club it dawn on to me it would look like a old shoe in a new shoe store.After all the industrial park consist of more modern industries such as a plastic manufacturer(gotta use those Atlas plastic hoppers somewhere),a distribution center etc.
Where to place "Godzilla" is another question..One thought is move it to the bottom right side.
As far as the second track..My thoughts is...
If I added that track first thing you know I would build my old door layout I had in the 80s while nice,it would not be the same as it was back then for several reasons..
