GETTING STARTED WITH ROUTE RELAY INTERLOCKING - PART 2

GETTING STARTED WITH RELAY INTERLOCKING - PART 2

From Next Part we will start learning Circuits but before that we should also know in Circuits what all things are going to see .

- First we will See The Station Yard Layout and in complete circuits we will create circuits according the the Same Layout. And the Layout is given Below.

- We will Start from Step by step i.e from start to end.

-  To Write any Circuit we should know the Flow chart  and based on that i will teach you how to write Circuit in a simple way .

- Lets see the Flow Chart First.

- Our target is to OFF the Signal to Green or Yellow according to our requirement. for that we have to press two button that is GN and UN.

- Means GN+UN and we have to reach till HR and in between many other circuits will come but it will b the part of HR Circuits.

- Circuits which we will be see in coming lessons are

1) SMCR

2)GNR

3) UNR

4) LR

5)NWKR/RWKR AND NWPR/NWPR MEANS POINT CIRCUITS

6) UCR

7)ASR/ALSR

8)OVSR

9)WLR

10)HR

11) UYR

12) GATE/CH CNL

13)TSR AND TPR

ETC

NOTE: 

To clear a Signal, SM has to ensure that the following conditions are fulfilled.


• The track circuits are clear.

• LC gate if any is closed

• Crank handles are ‘in’ and locked

• Knob of conflicting signals are normal

• Point knob is in centre position or in the same position of points required to be set

• Route is released after the last operation and not locked by any other conflicting signal.

• Point free indication, is available.

• SM key is `in’ and turned

• Line Clear obtained for LSS

• Time cancellation is not in progress
