Ah STOP boards.
Also shunt limit boards, which provide a blocking purpose to prevent shunting towards a signal at which another train could be perched.
We have em everywhere here.
Yes, I guess that some confusion could exist as to just who the train crew must beg permission to pass a stop board.
Generally here to enter a yard , or continue in a yard past STOP boards you were begging the shunters.
To exit a yard, you would be begging the signalman.
Though, in the Good ole Days, the shunter would be the bloke liaising with the signalman to grant permission to depart a yard.
A green handsignal from the shunter which would be acknowledged by a hooter blast.
What you didn't wanna hear were TWO separate whistle blast acknowledgements when rail activity was hectic in a yard.
OI, he was aiming that green handsignal at me NOT you !
Both shunters and signalmen are rare beasties these days outside of the smog hollow metrop.
Today TC would be the bloke to grant permission for passing stop boards, and he can be hundreds of miles away in some gloomy office.
Get caught nudging past a shunt limit board and you would be copping a bung.
Steve.
