A picture from ground level showing the cross girders being
fitted with steel supports for the third girder. This third girder would
support the brindle brick jack arching. After application of a layer of
protective asphalt to the topside of the brickwork arch a flat horizontal
surface was formed by filling in the voids with solid concrete. A steel plate
decking was secured to the top of the third girder, resting on this flat
concrete surface. The floor thus constructed was strong enough to support the
construction of normal trackwork arrangements with ballast and wooden sleepers
and the weight of locomotives and rolling stock. This construction resulted in
an equally distributed strength, which allowed flexibility for future
modifications to the track layouts without any structural changes being
necessary. On the left are the cross girders which will support the platform.
These cross girders have been positioned at a higher level and will not require
the brick jack arching as the loading requirements of the platform area was
significantly lower than that of the trackwork area.
