[FONT="]I'm working on a layout in TS2010. I have a yard that I wanted to have a low speed limit. I put signs at the entrance to the yard, but AI trains that start inside the yard still default to the standard 40mph. This is a well known issue, and I tried to solve it using invisible speed signs. I tried putting a sign at either end of each step of the yard ladder to catch trains going either way. So I setup the invisible speed sign on the west end. Then, when I setup the invisible speed sign on the east end, the one on the west end changed back to it’s default configuration. I can only setup up the sign on one end, but when I setup the other sign it changes the first back to default. The pointed end of the signs are pointing out (towards the switches). To setup the signs I’m clicking the "kph" to change it to mph, and then clicking the "disable", entering 10 and hitting return twice. When I’m done, the face of the sign displays the “10”. Does anyone know what I’m doing wrong here? I have a feeling that I’m missing something, but can’t figure out what.[/FONT]
