If when arriving at a station a guard inadvertently pressed the release buttons before opening the local door would all doors be released or is this only possible with the local door button activated?
Also does the buzzer only work if door interlock is made?
And yes the guard can only buzz when interlock is made
To be hoped that there is no need to use any of the other bell codes while the door is open. Are 5 for Guard/Driver leaving the train or 9 for police assistance required actually used in practice?

On a 150/1, the crew door isn't interlocked, so you can open it just before the train comes to a stop before opening the doors, and once the passenger doors are shut, you can give two on the buzzer just before you get back on, and close the crew door while the train is pulling away. It's different on a 150/2, as the crew doors are interlocked as they are used by passengers when units are coupled.
This would be against the policies of at least one TOC
considering the beeps can be heard in most units nowadays it wouldn't be that discrete.
If it wern't so many beeps most passengers wouldn't have a clue it was anything out of the ordinary.
Most certainly it is with my very safety conscious employer

And yet in the days of the slammers (less than 10 years ago, it was common for the guard to have his door open (it hinged inwards for this very reason) as the train pulled away.

Not on a 158, the local door switch activates the controls for the local door, but it doesn't open them.Equally it is possible for an overly enthusiastic Guard to hit the Local button too early and bring the train to a grinding halt! Not a popular move...
Which it doesn't do on a 158, because it doesn't open the doors.I think he meant actually operating the local door switch which would open the local door, break the interlock and stop a train rather quickly.
If by better you mean correct, yes. :roll:Okay operate the switch and hit the open button!
Is that better! :roll:
I think there's a terminology mix-up here - doesn't the 158 door control panel have a DKS operated by carriage key and then the local door is opened and closed using a rocker switch?
