Dear Members,
I am studying UK control table for Module 3 IRSE examination. In this I didn't find any locking related to Points crank handle.
I have working experience in Indian railway control table. There we mention for "Signal Control" concern point crank handle key should be in and locked in EKT and also we write the safe condition for crank handle release also. These condition we will implement in logic also. Apart from we are ensuring the safe condition to release the crank handle in degrade mode also (SSI failure)
I enquired few friends who are very familiar in UK signalling but I didn't get clear idea. Kindly clarify to me.
Thanks in advance !!!
Regards,
NJK
