Thanks for the info. I think I will delete them and rely on conventional signs. There are plenty of speed limit values in the AI for a variety of conditions. Thus no matter what signs you use, the AI will determine the the speed.
Thanks for all of the information. Too many conflicts between old stuff and new features.
I spent $30.00 to get a copy of a competitive product. My objective was to see if I could create a running railroad without illogical red signals, crashes, undocumented functions, odd AI, etc. While I like to plant trees and draw texture on the landscape, it is only in an effort to create further reality, as I see it. Alas that product was worse, in my opinion, compared to what I left behind several years ago. Just getting through the Steam purchasing processing was a nightmare. I was rewarded with low resolution (all settings to max) stuttering as the Horseshoe curve was negotiated. The high point was the houses. They were an accurate reproduction of what is still in the local towns and villages, with many coats of paint. Trees are 3 dimensional but low detail. The trains themselves were high quality since they were purchasable items.
So, the $30.00 was not a waste. It fortified the old saying "the grass is not always greener on the other side of the fence".
Having deleted the defective whistle posts, and deleted the invisible elements, it is time to look at the DLS to see what new events it can reveal after a full day of N3V programming.
