Northern Line management are proposing a change, to allow Line Controllers to authorise drivers to apply the rule over the radio. There are two big reasons why we should oppose this:
1. Is the radio actually secure?
2. It represents a change to the Rule Book as Line Controllers do not currently give authority. It should be the Station Supervisor, Signal Operator or Operating Official.
Funnily enough, this idea has been floated as part of the notorious Working Reference Manual review. Perhaps the Northern Line is flying a kite for management across the combine.
