Not sure that you can influence this Barry, but it seems to to take an age for the platforms to be identified on the main signage at London Bridge. It seems to be "our" trains that are problematic, i.e to ED or Denmark Hill , other trains have their platforms identified a good 10 minutes in advance. All all to often we are given 2 minutes to leg it down to Platforms 14, 15 or 16 and often along the platform to get to the far end, where our train is. The information staff seem to know what platforms a given train is coming into, but this doesnt translate itself into timely signage announcements. Its a pain and for those who arent fleet of foot, unfair and not customer focussed.
