When a signal indicates "Y3 track 2 facing," what does it signify for train movement?

The designation "Y3 track 2 facing" indicates that the train is cleared to proceed on Track 2. This type of signal provides specific instructions to the train crew regarding the safe movement and routing of the train. The term "facing" in this context means that the signal is intended for a train approaching the signal from a position that allows it to move onto the specified track, which in this case is Track 2.

This signaling is crucial for maintaining safety and efficiency within the transit system, as it informs the train crew that they have the authorization to continue their journey on Track 2 without needing to stop or await further instruction.
