With the thirties begins the story of a new building type, the railway station,[165] in whose sheds the mid century was to realize some of the largest and finest examples ever of ‘ferrovitreous’, or iron-and-glass, construction. The structures utilizing iron thus far mentioned have been of two sorts, some, such as bridges, markets, greenhouses, etc., with only subsidiary masonry elements, if any at all; others, examples of mixed construction with metal providing only the internal skeleton or the roof. Railway stations were generally—and before the fifties always—examples of mixed construction, but of a rather special sort. The iron and glass portions, that is the sheds, and the masonry portions are likely to be merely juxtaposed, not truly integrated. Such a masonry frontispiece as Hardwick’s Euston Arch in London of 1835-7 had no connexion at all with the functional elements of the station behind—here by Robert Stephenson—although Euston was an extreme case. But a happy co-ordination of the masonry and the iron-and-glass portions of stations was rarely achieved anywhere. Of the earliest railway station, that at Crown Street in Liverpool of 1830, nothing remains; it was in any case a very modest structure.[166] Of its successors at Lime Street the present station is the fourth on the site. Even the ‘Arch’ at Euston, the next major station to be built, is now gone, despite the strenuous efforts of the Victorian Society and others in Britain and overseas to save this symbolic portal to the Victorian Age. However, the first station at Temple Meads in Bristol, which was built by Brunel in 1839-40, is physically intact, though supplanted in present-day use by a larger and later one. Castellated as regards the masonry block in front, the shed here is equally medievalizing; for its roof is of timber, not of iron, and based on the fourteenth-century hammerbeam roof of Westminster Hall in London, whose width it exceeds by a few feet only. Of the once far finer Trijunct station at Derby, built in 1839-41, the last portions of Francis Thompson’s brick screen have finally been destroyed; the three original sheds provided by Robert Stephenson, with Thompson’s collaboration on the detailing, were each 56 feet wide in comparison to the 40-foot width of Stephenson’s earlier ones at Euston (Plate 62B). The tie-beam roof had much of the graceful directness and linear elegance of Rohault’s greenhouse or Veugny’s market.
