No, can only guess they are testing it as they had someone checking tickets there this morning. Gives us a taste of what is to come, an entire trainload queuing to get over the bridge, from what i could see, there was only just enough time to clear the platform from the train i was on (18.18 from LB) before the next southbound arrived. Can't imagine how anyone is supposed to get onto the southbound platfrom against the tide of people crossing the bridge.
