Don't know at Waterloo mate.
But down here the do everything to keep the station going, all the different people that entails, police, security network rail ect, builders , water companies ect,sales security, assist the disabled, old people those that can't for one reason or another use technology. , all sorts that you don't see on paper like talking people around that are not in a good place, dealing with the effects of it if they go under a train and the bit that nobody ever mentions dealing with the families afterwards because they always come to see were it's happened.
All sorts of stuff.
It's finished to be brutally honest, been heading that way for years.
