oThis system is generally provided at way side stations or small installations. o In this system for clearing a signal the route has to be correctly set by

operating the points individually to the required position. o System is more flexible due to the provision of more number of

facilities such as emergency operations and recording the same through counters. o Grouping of relays, makes the system more economical, reliable and

flexible.

CHAPTER 2

TABLE OF CONTROL, ROUTE SECTION PLAN

o Selection Table/Control Table is a tabular representation of Signaling arrangements provided in a particular Signal movements.

o It comprises of several columns and furnishes the details about various operating conditions for clearing the signals concerned.

o The selection table for a station is helpful for designing the circuits of that station and also is used for undertaking functional test of various signaling functions existing in the yard.

o The details given in the selection table is the basis of Interlocking provided in that particular yard.

GR1 Signal Controlling Relay No 1

o GR1, sticks through its own energised contact because

o When GLSR drops subsequently.

o Even if signal button is pressed unintentionally later.

o GR1 also has a condenser discharge circuit ,to prevent its dropping due to track circuit flickering.

o EGNR dropped contact is proved in GR1 circuit so as to drop it and put back the Signal to 'ON' aspect by an emergency operation.

G(R)LR :- Signal locking Relay :

oThis relay is an interlocked relay. The energization of top relay G(R)LR locks the signal and bottom relay G(N)LR unlocks the signal.

oThe signal locking relay is provided one for every exit track and is common for both directions.

o It prevents the clearance of any other signal for that line from any direction after a signal has been cleared.

oThis relay is named after the Exit or Berthing track.
