Thanks for the reply and I was afraid it was because some of the people were stuck in their tracks
I've also had the same experience as Bob, 2 years and running and only 1 SBHH while route building. I'm not sure what I did, but when I restarted the World Editor every thing was still good to go. In the other sim if you didn't save every time you placed an object you were taking big chances and there were a few times the route would crash, you restart the editor and your track was floating in mid air.
Jerry keep up the great work on your NS route, it looks fantastic. I also want to thank you for all of the really nice objects you've created for the community, your crossing signals, signals, homes and wayside buildings are all top notch
