| A distant will not change from Yellow to Green until all the section signals are off, except where a train has already passed it before the section is fully cleared. Distant will be replaced when a train reaches a trigger point, which will normally be the first (normally) displayed track circuit. | A distant will not change from Yellow to Green until all the section signals are off, except where a train has already passed it before the section is fully cleared.

| - | Home signals must be pulled off in the correct order, which is generally the direction of travel. Shunt routes pulling order may vary- see individual boxes. You will not be able to pull off a home if the next one is already off- in other words you must replace all the signals once a train has passed to be able to start the sequence again (as above signals will not [[usertrack:glossary:torr|TORR]]). | + | Home signals must be pulled off in the correct order, which is generally the direction of travel.

| - | In order to maintain the correct train dynamics some of the ‘home’ signals are in reality 3 aspect with a hidden Yellow. If a train passes a Distant at Yellow then any intermediate home will be read as a Yellow too and the train will travel at the appropriate speed (max 40mph) till the end of the section and there is a Green. | + | In order to maintain the correct train dynamics some of the ‘home’ signals are in reality 3 aspect with a hidden Yellow.

| - | In a number of areas (Larbert Jn especially) you will see what looks like 4 aspect signalling- this is where the Distant signal of one box shares a post with a home signal of another. The train dynamics read the signal as being the most restrictive aspect displayed, which ever that is. | + | In a number of areas (especially Larbert Jn) you will see what looks like 4 aspect signalling - this is where the Distant signal of one box shares a post with a home signal of another.

| - | Clearing points are essentially an overlap but not interlocked to the signalling and it is possible to violate them for which there will be a penalty. In most cases the clearing point is the TC immediately beyond the first Home signal. There are two clearing point set-ups available to set at sim launch using ‘[[usertrack:mans:cscotlaunch|Easy Mode]]’. | + | Clearing points are essentially an overlap but not interlocked to the signalling and it is possible to violate them for which there will be a penalty.

| At Stirling station it does get a bit more involved; to the South of the station the clearing point extends across several track circuits and the pointwork. However, once an UP train has come to a halt at a platform you may signal a train across the clearing point for no penalty. | At Stirling station it does get a bit more involved; to the South of the station the clearing point extends across several track circuits and the pointwork.

| - | A couple of signals can’t be pulled off till track circuits are occupied for a length of time; you will receive a message “route not ready to release” if early pulling off is attempted. Details are in the sections dealing with specific locations. | + | A couple of signals can’t be pulled off until track circuits are occupied for a length of time; you will receive a message “route not ready to release” if early pulling off is attempted.
