Is approach release fail safe?
#4
The reason why i have started this debate is:

The concept of "Approach control" is to mainly reduce the train's speed to a certain extent by keeping the signal at red/yellow. But this is achieved and mainly based on its berth track occupied condition...
What if the berth track is failed in the de-energised condition? That can easily turn the approach controlled signal to get cleared which is not fail safe.

Any more views on this? Or plz correct me if i am thinking wrong....

Regards,
Saraswathi.
