Dear Members,
I have few doubts in Rayne's park control.
Normally if we provide approach control for one signal means, then the aspect sequence for that line will be modified aspect sequence.
In the example of 3 aspect case, Consecutive yellow (Signal in rear to the approach controlled signal will show yellow, Approached controlled signal will show RED, once the train occupies the berth track of approach controlled signal, then it will go to yellow ) will be provided.
Here my doubt is how the failure of approach controlled signal's TPR will result in signal in rear show higher aspect then the permissible single yellow (Green in case of 3 aspect).
The signal in rear will show green only when the approach controlled signal is green.
Or else the modified aspect sequence is introduced only after the incident in Rayne's park ?
Please find the attachment also. Kindly clarify my doubt. If I am wrong kindly correct me
Regards,
NJK
