This update to V3 allows the black points levers to be used with switches on the main line. When an AI train is programmed, in a non-free-roam scenario, to go through the points, the internal dispatcher code will lock the points in the required position. If you click on the black lever, a message will appear saying the points are locked by a particular service. Once the train has gone past, and no other service is locking the route, the player is free to click on the lever and switch the points. In free roam, you can do it at any time.
Note that the signal levers (red and yellow) are not controlled directly by the player. They simply mimic the position of the signal arms, that are themselves instructed to move by the RW dispatcher code. So, you can't click on them, but even so, it's nice to see them move in sync with the signal arms.
I've also uploaded, separately, a model of a signal lamp indicator, to go on the block shelf, next to the other instruments. It adds to the overall atmosphere inside the signal box.
