With the additional stair, the designs have doubled the stair-capacity to the platforms and greatly improved passengers’ safety. In addition, new fencing has been designed and delivered along the length of the platform, skilfully avoiding the abundance of buried services below platform level, and providing a buffer zone between waiting passengers, and high-speed trains, to and from Paddington.
Collaborating with Morgan Sindall Infrastructure, Frankham Consultancy Group,Fourway, SM Engineering and AJ Wells, BPR's design used a facing-brick coursing that loosely-recalls the historic booking hall, as well as a contemporary Vitreous Enamel-clad parapet to the stair, to provide guarding around the stairwell.
