Thank you for the replies, Dave, Chris.
Dave, it is cleaner and allows for industry on both sides of the track. A coal dealer, perhaps.
Chris, I was looking at the layout last evening pondering exactly what you asked. The only way would be setup to push a car in and pull it out. However, it would be awkward at best. The run around would let me pull a car in and run around to push it back into the siding. I'm going to not change anything right now and do some switching to the imaginary industry which I actually haven't done yet. Yes, the track has probably been in this configuration for 2 years, and I haven't done anything except use it to hold cars.
