What type of signal controls the movement of trains when approaching a Home Signal?

The type of signal that controls the movement of trains when approaching a Home Signal is an Approach Signal. This signal is positioned in advance of a Home Signal and serves two vital functions: it informs the train crew of the status of the Home Signal ahead and prepares them to adjust their speed accordingly. If the Home Signal is displaying a stop indication, the Approach Signal allows the crew to slow down in a controlled manner, thus ensuring safety as the train approaches the signal. The Approach Signal enhances operational efficiency by providing essential information well in advance of reaching the Home Signal, minimizing abrupt stops and potential disruptions to the flow of rail traffic. This way, the train can safely prepare for stops or changes in signal indication.
