Indian Railways
World’s second largest railway network
Approximately 65,000 km of rail tracks and over 7,000 railway stations.
IR owns a fleet of
2.5 lac wagons
40,000 coaches
7,500 locomotives
Operates 1,60,251 trains including 9,550 passenger trains, carrying about 1.6 million tonnes of freight and about 18 million passengers daily
RAILWAY SIGNALLING:-
Railway signalling is a system used to control railway traffic safely, essentially to prevent trains from colliding.
There are following type of signals:
Semaphore
Colour light signal
Position light signal
INTERLOCKING:-
Interlocking means an arrangement of signals, points and other appliances, operated from a panel or lever frame, so inter-connected by Mechanical locking or Electrical locking or both that their operation must take place in proper sequence to ensure safety.
Types of Interlocking:
i) Mechanical Interlocking.
ii) Panel Interlocking (Relay).
iii) Route Relay Interlocking.
iv) Solid State Interlocking.
ROUTH RELAY INTERLOCKING
Route Relay interlocking is same as Panel Interlocking with Electro Mechanical Relays doing the Interlocking except that it can be employed for big yards.
the interlocking is done between one route and another route.
Another Important feature in terms of operating point of view is that the SM has to only press two buttons, Signal button & Route Button (entry-exit system).
He doesn’t have to individually operate the points to the required position.
