Overview
A signal is an indicator that through some sort of means conveys the status of the track ahead to drivers passing it. This could be 3 or 4 lights mounted on a pole or shunt signals near the ground producing a white and red pattern.
Mechanics
Signals work by using sensors mounted on the track to check if a train is present. The sensor in question will then report its status to a signalling centre (in SCR, Stepford ROC) and will change the signal aspects behind it to tell drivers that they need to slow down and stop as their route cannot be set due to a conflicting move or train in front.
Signal Meanings
A green aspect (Proceed) tells the driver that their route is clear and that they can proceed at line speed. The next aspect is usually green but can sometimes be (double) yellow. If this signal is next it will trigger an electrical ping from the AWS. This ping does not have to be acknowledged and is there to alert the driver.
A double yellow aspect (Preliminary Caution) tells the driver that two signals ahead their route is not clear and they must slow down in preparation to stop at the red signal. The next aspect will always be yellow unless it changes as more of the train's route is clear. An unofficial advised speed past this signal is 70-80. If this signal is next it will trigger an AWS horn in the form of a loud continuous beep and must be acknowledged by the driver by pressing 'Q' or by clicking the warning symbol.
A yellow aspect (Caution) tells the driver that the next signal is red (danger) and that they must slow down in preparation to stop at the next signal. The next aspect will always be red (danger) unless it changes as more the train's route is clear. The speed limit on SCR past this aspect is 45. If this signal is next it will trigger an AWS horn in the form of a loud continuous beep and must be acknowledged by the driver by pressing 'Q' or by clicking the warning symbol.
A red aspect (Danger) tells that driver that they must stop at this signal and the driver must fully stop by the signal. The driver may not proceed past this signal and if they do, automatic emergency braking is applied and will bring the train to a halt. The term for passing this signal is Signal Passed at Danger (SPAD). The train has no clearance beyond this point. If this signal is next it will trigger an AWS horn in the form of a loud continuous beep and must be acknowledged by the driver by pressing 'Q' or by clicking the warning symbol.
Shunt Signals
This signal is currently only found in Faymere Green TMD and the Coxly Station and Bypass Sidings. It is mounted to the ground unlike regular signals. It has 3 lights in a triangular shape and 2 white lights mean proceed at caution whereas any other indication should be taken as a stop signal or a malfunction. The stop signal is 2 red lights.
