Of course it needs redeveloping - London Bridge station can barely cope as it is. Over recent years you've had More London bringing huge numbers of extra people in, and with the Shard becoming habitable in the next few months and also the Place opposite, London Bridge station will only get busier.
It is a real shame they didn't do the redeveloping the right way round, getting the infrastructure in place before the extra people arrived.
The majority of work that has the potential to be noisy is scheduled to take place during our normal working hours (Monday – Friday, 8am – 6pm and Saturday 8am – 1pm). In some circumstances, however, work requires the closure of the railway. Unfortunately in these instances we have no choice but to work at night or during the weekend as this is the only time when the trains are not running. When this happens we take all practical measures to minimise noise and disturbance, in consultation with the London Borough of Southwark.
Why do I feel this is so going to be a major issue over the coming years for everyone in the area *sighs loudly*
