Answer

Wow!  I didn't know this and I'm English!

Answer

ON the platforms, you will find a speaker in the walls of the station.  There is a button next to it and if you press the button then you will be able to use the speaker to talk to a staff member.  These are used to do things such as find out when your next train is, on occasions where the display board is not working.
