Signalling Solutions & Architectures
Panel Interlocking
Panel interlocking is a railway signalling system where track points and signals are safely operated from a centralized control panel by station master through electrical circuits and uses of relays to prevent conflicting route settings, where trains cannot be directed onto the same track simultaneously. This system replaces manual lever frames, significantly reducing human error and improving operational efficiency. Safety overrides are built-in, meaning a signal will automatically remain red if the chosen path is blocked or unsafe.

Route Relay Interlocking (EI) is an advanced railway signalling system that automates the setting of points and signals for an entire train route through a central control panel. With a single command, the system automatically checks for track clearance, aligns the necessary switches, and clears the signals safely. It uses a network of electrical relays to physically prevent conflicting train movements, eliminates human error, and significantly enhances operational safety. By streamlining route clearance, EI drastically reduces train delays and increases the efficiency of busy and Big Railway stations.

Automatic signalling is a railway system where signals are controlled entirely by the movement of trains rather than human operators. The tracks are divided into distinct sections called automatic block sections that detect a train's presence using track circuit or Axle counter devices. When a train enters a section, it automatically sets the preceding signal to Red to prevent rear-end collisions. As the train advances, the signals automatically clear back to yellow, double yellow and then ultimately to green aspect to guide following trains safely. This system significantly increases track capacity and safety by allowing trains to run closer together.
