firth of forth bridge collapse

[165][166], The disaster inspired several songs and poems, most famously William McGonagall's "The Tay Bridge Disaster", widely considered to be of such a low quality as to be comical. Bouch died less than a year after the disaster, his reputation ruined. Forth Bridge, railway bridge over the Firth of Forth, the estuary of the River Forth in Scotland.It was one of the first cantilever bridges and for several years was the world’s longest span. The metal, as one would expect in the thin part, is very imperfect. A flash is seen-the Bridge is broke- He was unwilling to quantify the amplitude of motion, but when pressed he offered 2 to 3 inches (51 to 76 mm). De brug werd in 2015 op de Werelderfgoedlijst van de UNESCO geplaatst. [119] Cochrane and Brunlees added that both sides of the carriages were damaged "very much alike". Bouch's counsel called witnesses last; hence his first attempts to suggest derailment and collision were made piecemeal in cross-examination of universally unsympathetic expert witnesses. By fitting an additional packing piece between loose cotters and driving the cotters in, Noble had re-tightened loose ties and stopped them chattering. [91] This advice had been endorsed by a number of eminent engineers. Plans for a chain bridge across the Firth of Forth were drawn up in 1817 by Edinburgh civil engineer and land surveyor James Anderson. Did you scroll all this way to get facts about forth bridge print? Law had seen no evidence of burnt-on lugs. He was referring to advice given by the Astronomer Royal, Sir George Biddell Airy in 1873 when consulted about Bouch's design for a suspension bridge across the Firth of Forth; that wind pressures as high as 40 psf (1.9 kPa) might be encountered very locally, but averaged over a 1,600 ft (490 m) span 10 psf (0.48 kPa) would be a reasonable allowance. Future British bridge designs had to allow for wind loadings of up to 56 pounds per square foot (2.7 kilopascals). If only there had been 28 supporting piers stretched out across the Firth instead of 14. If the second-class carriage body had hit anything at speed, it would have been 'knocked all to spunks' without affecting the underframe. Memorials have been placed at either end of the bridge in Dundee and Wormit.[163]. When completed, it stood – and stands – 60 yards to the west of the original structure: with all its 85 piers in an exact straight line. And loud the wind did roar; See more ideas about Firth, Forth bridge, Scotland. It resembles both the Golden Gate Bridge in San Francisco and the Ponte 25 Abril in Lisbon. Here (producing a specimen) is a nodule of cold metal which has been formed. Black explained that the guard rails protecting against derailment were slightly higher than and inboard of the running rails. n 1849, aged just 26, Thomas Bouch was precociously promoted to chief engineer and manager of the Edinburgh, Perth and Dundee Railway, the predecessor of North British Railway. After the dread and dreadful fall, the splash, the clank, a few shrieks and yells, numb shock, stricken men and women fighting for air, injured, freezing, drowning, last air bubbles also attempting to surface. 241–271(H Law); the bridge design process in Minutes of Evidence pp. To reduce the weight these had to support, Bouch used open-lattice iron skeleton piers: each pier had multiple cast-iron columns taking the weight of the bridging girders. The Forth Bridge opened in 1890 at the Queensferry crossing, and only local branch lines approached the location. [55], Gilkes' site staff were inherited from the previous contractor. 1873: 5 August, the North British Railway obtains initial authority to build a suspension bridge across the Firth of Forth. [35][note 9] The Dundee stationmaster had passed Robertson's complaint about speed (he had been unaware of any concern about oscillation) on to the drivers, and then checked times from cabin to cabin (at either end of the bridge the train was travelling slowly to pick up or hand over the baton). [118] The physical evidence put to them for derailment and subsequent impact of one or more carriage with the girders was limited. Instead, the train had been encased; and it was within latticework that there had been the greatest potential for derailment. Law's sums appear (with the wrong number and units at a crucial point) on p. 248 of the Minutes of Evidence; the correct version would seem to be this: The bars had a cross section of one point six two five square inches (10.48 cm. [note 14] If a casting had blowholes or other casting defects considered to be minor faults, they were filled with 'Beaumont egg'[note 15] (which the foreman kept a stock of for that purpose) and the casting was used. By 3 January 1880, they were taking evidence in Dundee; they then appointed Henry Law (a qualified civil engineer) to undertake detailed investigations. Prior to the bridge, Bouch’s first undertaking was to make the docks of Tayport on the south bank of the Tay, opposite Dundee, far more efficient in its transit of passengers – and more importantly, bulky goods and minerals by ferry: specifically the world’s very first rail-wagon ferry, Leviathan. [134], According to Yolland and Barlow "the fall of the bridge was occasioned by the insufficiency of the cross-bracings and fastenings to sustain the force of the gale on the night of December 28th 1879 ... the bridge had been previously strained by other gales". One-hundred-and-forty-two not entirely fluent lines follow; and allowing for one or two factual inaccuracies, the author takes us right through the tragedy as it unravels. Yolland and Barlow concluded that the bridge had failed at the south end first; and made no explicit finding as to whether the train had hit the girders. "[134], Yolland and Barlow also noted the possibility that failure was by fracture of a leeward column. [37], Painters who had worked on the bridge in mid-1879 said that it shook when a train was on it. And a citizen good at stopwatch reckoned more than one northbound engine emerged from its metal box, ready for its one in 73ft descent into Dundee, after only 50 seconds instead of a scheduled 60 to 65 seconds. [3], The bridge was built by Hopkin Gilkes and Company, a Middlesbrough company which had worked previously with Bouch on iron viaducts. Beautiful Railway Bridge of the Silv’ry Tay! [note 29]. It was opened on 4 March 1890, and spans a total length of 8,296 feet. nonetheless Noble should have reported the loose ties. [114][120], Bouch pointed to the rails and their chairs being smashed up in the girder holding the last two carriages, to the axle-box of the second-class carriage having become detached and ending up in the bottom boom of the eastern girder,[121] to the footboard on the east side of the carriage having been completely carried away, to the girders being broken up, and to marks on the girders showing contact with the carriage roof,[122] and to a plank with wheel marks on it having been washed up at Newport but unfortunately then washed away. [130], The three members of the court failed to agree a report although there was much common ground:[131], Rothery added that, given the importance to the bridge design of the test borings showing shallow bedrock, Bouch should have taken greater pains, and looked at the cores himself. For a year, painters and platelayers reported “chattering ties”; also vertical and lateral vibration whenever trains passed: movement measured between 0.5 and two inches wide of tolerance. They had had to be broken up with dynamite before they could be recovered from the bed of the Tay (but only after an unsuccessful attempt to lift the crucial girder in one piece which had broken many girder ties). Just 50 years from the birth of passenger railways in Britain, this was a task too daunting; strong side-winds, fog, extremely busy river traffic, soft bedrock and low capital reserves made it nearly impossible. Maxwell, an engineer, thought the flashes too red to be friction sparks unless tinged by ignition of gas escaping from the. [141], Rothery's minority report is more detailed in its analysis, more willing to blame named individuals, and more quotable, but the official report of the court is a relatively short one signed by Yolland and Barlow. Its share of Edinburgh-Dundee traffic immediately diminished from 85 per cent to 51 per cent. [125] The tender coupling (which clearly could not have hit a girder) had also been found in the bottom boom of the eastern girder. The train is heard no more. Almost instantly, the carrier was able to expand its traffic at the expense of its bitter rival: the Caledonian Railway – which hitherto owned rails all the way to Dundee on a complete and coordinated, but as long as it was tedious, railway route. Evidence was taken from scientists on the current state of knowledge on wind loading and from engineers on the allowance they made for it. He had also seen this on the previous train. Whilst checking the pier foundations to see if the river bed was being scoured from around them, Noble had become aware that some diagonal tie bars were 'chattering',[note 11] and in October 1878 had begun remedying this. Steam power came to the Firth of Forth in 1821 with the launch of the paddleboat Queen Margaret. 427–429 (Sir Thomas Bouch), Mins of Ev pp. Gilkes were in some financial difficulty; they ceased trading in 1880, but had begun liquidation in May 1879, before the disaster. This is the first crossing to be built over the Firth of Forth and was constructed by the Victorians who knew how to build things to last. And many Dundonians had a premonition regarding the frailty of this very novel bridge. [84][note 20] However, both ties and sound lugs failed at loadings of about 20 tons, well below what had been expected. Are numbered with the dead. Forth Road Bridge Parallel aan de Forth Railway Bridge ligt de Forth Road Bridge. Ironically, a disgraced Sir Thomas Bouch did – unknowingly – leave some outstanding bequests. C. Horne's ballad In Memory of the Tay Bridge Disaster was published as a broadside in May 1880. Find the perfect Firth Of Forth Rail Bridge stock photos and editorial news pictures from Getty Images. [2] The southern and central divisions were nearly level, but the northern division descended towards Dundee at gradients of up to 1 in 73. Forming a mould around the defective lug, heating that end of the column, and adding molten metal to fill the mould and – hopefully – adequately fuse with the rest of the column. I am very sorry to say That ninety lives have been taken away On the last Sabbath day of 1879, Which will be remember’d for a very long time. Construction began in 1871 of a bridge to be supported by brick piers resting on bedrock. Two witnesses, viewing the high girders from the north almost end-on, had seen the lights of the train as far as the 3rd–4th high girder, when they disappeared; this was followed by three flashes from the high girders north of the train. [123] Bouch's assistant gave evidence of two sets of horizontal scrape marks (very slight scratches in the metal or paint on the girders) matching the heights of the roofs of the last two carriages, but did not know the heights he claimed to be matched. A paste made of beeswax, fiddler's rosin, fine iron filings and lampblack, melted together, poured into the hole and allowed to set. Airy said that the advice given was specific to suspension bridges and the Forth; 40 psf (1.9 kPa) could act over an entire span of the Tay Bridge and he would now advise designing to 120 psf (5.7 kPa)(i.e. Curiously, on the riverbed, certain debris was found to have fallen eastwards, not west in line with the fierce winds. [88][note 24] Bouch said that whilst 20 psf (0.96 kPa) had been discussed, he had been 'guided by the report on the Forth Bridge' to assume 10 psf (0.48 kPa) and therefore made no special allowance for wind loading. So it was a second Tay Bridge, double-tracked, designed by none other than the accomplished WH Barlow and built by a brilliant William Arrol that was an understated triumph when it opened on 11 July 1887. [41] The shaking was worse when trains were going faster, which they did: "when the Fife boat was nearly over and the train had only got to the south end of the bridge it was a hard drive".
