One hears the continual station announcements about trains at "Platform A" or "Platform B".
Has it been noticed that there are seemingly no signs at all showing in this manner which of the platforms are being referred to.
Apart from the big signs at the base of platform escalators pointing the way to platforms A and B? Or do you mean something else?
Is it like on the Tube where almost every sign that says "North/South/East/Westbound" also says "Platform X" but even frequent users (like me) can go years without realising that the platforms have numbers because we're so focused on just looking at the information we seek (X-bound, and the line diagram showing the stations) while subconsciously blocking out everything else?
For example,
in this Geoff Marshall video, looking just at the Paddington station bit from 0:51 onward:
* The first shot is of an announcer standing in front of a Platform Edge Door wall that says "Westbound Platform B"
* The second shot is of a train arriving, with an overhead sign showing "Westbound Platform B" and a similar PED wall sign as above
* The third shot is of Geoff standing under two escalators, with big line diagram signs titled "Westbound Platform B" and "Eastbound Platform A"
The only signage that does not say A/B on it seems to be the live departure information above each PED.
It does appear (from other youtube videos) that in stations with separate platform tunnels for the two directions, the signage is mainly concentrated to the junctions between passageways (again stating both direction and letter), and there are fewer signs on the platforms themselves stating what the current platform is (for example,
this video tour of Whitechapel station by Ismail's Transport Network, from 5:50 to 10:50 shows a walk along the eastbound platform but I can only see two signs - one at each end - showing "Eastbound Platform A", and I can't see any line diagrams at all). If the announcements at those platforms mention "Platform A/B" then it would be good if signs stating "Platform A/B" could be visible from every point on the platform.
