line from , with the expresses worked by Class 45 and Class 46 Peaks and Class 47s and Deltics appearing on the farewell specials. Local trains were mainly worked by Class 26s supplemented by Class 25s and Class 37s, while freight services were hauled by a variety of classes including Clayton Class 17s. The Waverley Route had a small number of minor engine sheds and two major sheds at its northern and southern extremities. The smaller sheds were at Galashiels, St Boswells, Riccarton Junction and Hardengreen Junction; Hawick had a larger facility which was important for the operation of the Waverley Route and its branch lines. St Margarets and Carlisle Canal were the major sheds; St Margarets had been the original NBR shed in the Edinburgh area and remained an important facility well into the 1960s. Although smaller than St Margarets, Carlisle Canal played a vital role in the operation of the Waverley Route and even with the line's decline post-nationalisation, there were still over 50 locomotives stabled there in the mid-1950s. Major structures and earthworks The Waverley Route, and particularly the section between Dalhousie and Hawick, required heavy construction works with numerous viaducts, cuttings and embankments. To take the line through Hawick, the five-arch Teviot Viaduct at the south end of Hawick station passed over the River Teviot at a height of and was followed by a embankment, while further down the line Hurdie's Hill cutting above Hawick was and deep. Similarly, Lynnwood Viaduct, which bridged the Slitrig Water between Hawick and Stobs, had six arches above the water and followed by a cutting. On the same stretch of line at Acreknowe, a and deep cutting was blasted through rock. The fifteen spans of Shankend Viaduct at the south end of Shankend station were high, while on the approach to Whitrope, Ninestanerigg cutting was in length and deep and was followed by a embankment. The other viaducts of note were the 22-arch Newbattle Viaduct across the South Esk valley which stretches and the Redbridge Viaduct across the Tweed by Galashiels. The Whitrope Tunnel was the route's most significant engineering work and was bored through a combination of old red sandstone conglomerate resting on clay slate, stratified sandstone and beds of shale intermixed with bands of limestone and sandstone. The Waverley Route's only other significant tunnel was the Bowland Tunnel which traversed the 'bow' of Gala Water by Bowshank. The
