Tay Bridge disaster that the wind pressure on the high girders had been no more than , from the absence of damage to vulnerable features on buildings in Dundee and the signal cabins at the south end of the bridge. The Inquiry felt that these locations were significantly more sheltered, and therefore rejected this argument. Baker's subsequent work on wind pressures at the Forth Rail Bridge site showed meteorologists "were" overestimating, but his might have over-interpreted the data. Law had numerous criticisms of the bridge design, some echoed by other engineers: Both Pole and Law had calculated the wind loading needed to overturn
Tay Rail Bridge covered by a total of 85 spans. These spans are ordinary brick arches, backed by cement concrete and set on top of piers which are supported by pairs of columns. Wanting to avoid a repeat of the fate of the First Tay Bridge, a principal intention of the design is stability, followed in importance by measures to minimise the bridge's weight and the adoption of aesthetically pleasing shaping where possible without compromising on structural strength. The piers, which are primarily built from brick and concrete, are enclosed by a wrought iron caisson up to the low-water mark, above which a
