As you can see there are two settings for Id, 1 and 2. These are used on the permissive signals as they have 2 signs attached to their posts. Each ID can be 4 digits. Id1 will show in the top sign and Id2 will show in the bottom sign. By default, if these are left blank the permissive signals will put the letter “P” on the top sign and “32/4” in the bottom sign. You may choose to use the ID for putting the mile marker on the post or some other text.
Below the ID’s are the lines for each link, in this example there are 2 links. Link 1 will be the straight-through route and link 2 covers the diverging route. In this example, the speed “Spd” column is not set for link 1 and is set to 15mph for link 2. Link 1 will use whatever speed the track is set to where the actual link is placed. This is how you set the speed limit for the junction. Link 0 will always use the track speed so set your track speeds.
There are two more boxes used on these signals, the “App” box and the “Limit” box. The “App” box stands for approach. You can set any signal to be an approach signal. You will ONLY set link 1 to use this setting. This tells the signal to act as an approach signal.
