The access walkways and staircases were all prefabricated off site and lifted into place over one weekend by a huge crane. It was all ready to go the next monday morning. Incredible bit of construction. It will in time add lifts to all platforms and is part of the platform lengthening. New toilets, waiting room and information systems have be ready for some time. Its all very welcome. Hopefully things will continue to improve in ThorntonHeath!
