So the Platform Closed ‘crosses’ are ‘interlocked’ with the visual display on the indicators but not the ‘press to talk’ Tannoy? Are the two means of communication operated by different people/ organisations?
You would have thought they were both managed locally by Euston’s control room however it’s a unique setup which to me sounds like a separate system which also needs to be updated alongside the software for the CIS for the platform. Which would be totally ridiculous, but this is Euston so nothing surprises me…
