An elevation of the special stage spanning the four tracks
between the main platforms and resting on the three pairs of wheeled trestles.
A roof girder is shown in position above the special stage. The distance
between the two supporting columns on each platform was 103 feet, but the
longest roof girder was 276 feet long and weighted 15 tons. In total fourteen
roof girders were required and in each transverse bay there were six roof
trusses. After the erection of each transverse bay the temporary rails were
extended along each platform and the special stage moved on the trestles a
distance of 35 feet 10 inches to its next position.
