one designed by Sir Thomas Bouch, which had collapsed in a storm in December 1878. This second one was designed by William Henry Barlow (1812-1902), who had sat on the board of Enquiry for the disaster, together with his son Crawford Barlow. Built by Tancred and Arrol of Glasgow from 1882-87 to carry the North British Railway, it is a little upstream from its ill-fated predecessor, and carries two tracks instead of one. With 84 spans and a length of 3.26 km, it is still the longest railway bridge in Britain (see Gifford 146). [Click on this and the following images for larger pictures.], crossing the Firth of Tay from Dundee to Wormit, Fife, in Scotland, replaced the
"At the navigation spans [the piers] support hog-back shaped lattice girders through which the tracks are threaded" (Gifford 146-47).
This photograph clearly shows the bases of the old piers just beyond the newer ones.
The primary objectives, as always but especially in this case, must have been strength and safety. According to Grace's Guide, the Barlows
used massive monocoque piers to support a double railway track, ... made from wrought iron and steel. The old brick and masonry piers from the first bridge built by Thomas Bouch were retained as breakwaters for the new piers upstream. They can still be seen today as a forlorn reminder of the tragedy of 1879.
John Gifford calls the bridge "unexciting" (146), but there are several other points of interest. For example, the spans are the same as those on Bouch's bridge, allowing some of its iron girders to be reused; the wrought-iron latticework accommodates service pipes; and although "[s]tructural steelwork was then a technology at this time and it was used in the decking and for some internal frameworks within the piers" ("Tay Rail Bridge"), the structure is still mainly of wrought iron, making it "the last of the great wrought iron railway bridges" ("Dundee: Tay Bridge"). The bridge was opened to coincide with Queen Victoria's Golden Jubilee, on 20 June 1887.
