Photography was very challenging during the day due to the sheer volume of visitors. A "Groupon" offer had clearly attracted a huge increase in the number of visitors especially those with pushchairs. A railway yard is not ideal for the 4-wheel baby carts so congestion was significant at several "Pinch" points. Most difficult to negotiate was access through the works. A traffic light system was operating with queues on both sides of the stairs up to the viewing gallery. Of course having bench seats up on the balcony was also a major problem. Overall though it must have been a financial success.
