A signal is a device to communicate to Loco Pilot to go ahead or stop.
Signalling system facilitates the safe and efficient movement of trains on the railway.

Key Lock Inter locking
The human
element :
• Setting of the point and locking is entirely manual through key and lock system.
• Signals controlled by levers situated at the signals.

Mechanical Signaling
Operation of Points and Signals from a fixed location with group of levers through rigid connection (Rod / Wire)
System is interlocked mechanically by grouping the levers.

Electrical Signaling
Panel Interlocking
• Signals controlled by Operation from a Panel through cables by electrical means.
• Each function to be operated individually
• Interlocking is achieved through relays.

Route Relay Interlocking
Individual operation is avoided.
Final function is achieved
though pre-defined automatic operation
.

IBS / Automatic signaling
IB / Automatic Signaling enhances the section capacity
Automatic signals are self controlled and avoids human operations

Electronic Interlocking
Operation is done through computer or Panel
Microprocessor based interlocking system
Interlocking is achieved through Software.
