OK, here's some pics I scanned today from a wee book called Glasgow Stations, by Colin Johnston and John R Hume. It was published in 1979, and is a little mine of info on the main stations in the city. Hope you all enjoy...
Bridge St Station as it looked after the 1885 rebuild.
The construction of the first Central Station viaduct, circa 1876.
Construction of the undercrofts of Central Station, 1877.
More undercroft construction. The street crossing the picture is Midland Street, where the original entrance to The Arches is now.
Construction of Low Level, about 1895. The roof and girderwork sill looks much the same in places where the ugly yellow cladding isn't hiding it today!
Central Hotel under construction, 1880.
The new viaduct under construction, in 1901. The book offers no help on the date of removal of the original viaduct. reiterating only that it was in poor condition and rendered superfluous by the 1961 signal work.
One of a couple of sneaky wee images of Buchanan St Station. This facade dates from 1932, although the pic looks to be about 60s, since Buchanan House is being built in the background, and the cars are all of that era too.
Buchanan St Station interior, about 1960.
