'...staff make "next train" announcements that are broadcast all down this end of the line.'

Eh? Broadcast? How does that work? The next train from Ladbroke is surely not, at that moment, also the next train from Goldhawk, is it? Unless they are very infrequent. Or are the broadcasts somehow timed to move up and down the line at train speed?
I don't know how announcements work at intermediate stations but at Paddington they have announcements like:

The next train has just left Ladbroke grove and will be at Westbourne Park in 2 minutes, Royal Oak in 4 minutes and Paddington in 6 minutes
