the tay bridge disaster

So the train mov’d slowly along the Bridge of Tay,Until it was about midway,Then the central girders with a crash gave way,And down went the train and passengers into the Tay!The Storm Fiend did loudly bray,Because ninety lives had been taken away,On the last Sabbath day of 1879,Which will be remember’d for a very long time. nonetheless Noble should have reported the loose ties. Had they been supported on each side with buttresses. "[139] Rothery dissented, feeling that it was for the engineers themselves to arrive at an 'understood rule', such as the French rule of 55 psf (2.6 kPa)[note 32] or the US 50 psf (2.4 kPa). [note 3] When the train failed to appear on the line off the bridge into Dundee he tried to talk to the signal cabin at the north end of the bridge, but found that all communication with it had been lost.[18]. Although the Tay Bridge disaster is prominently featured in this book, the reader is also treated to a history of meteorology in Great Britain, an account of the engineering failures that led to the Challenger Space Shuttle Disaster, the histories of Perth and Dundee, the art of bridge construction, and so forth. 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. [note 21] After the accident Stewart had assisted William Pole[note 22] in calculating what the bridge should have withstood. If the second-class carriage body had hit anything at speed, it would have been 'knocked all to spunks' without affecting the underframe. Construction began in 1871 of a bridge to be supported by brick piers resting on bedrock. Oh! Despite well over a century of subsequent train travel, the Tay Bridge disaster remains one of Britain’s worst ever railway accidents. Thomas Bouch: Architect of the Tay Bridge disaster. The gradient onto the bridge at the northern end prevented similar high speeds on south-bound locals. That your central girders would not have given way. Work started 6 July 1883 and the bridge opened on 13 July 1887. Beautiful Railway Bridge of the Silv’ry Tay! North-bound local trains were often held up to avoid delaying expresses, and then made up time while travelling over the bridge. Although the Tay Bridge disaster is prominently featured in this book, the reader is also treated to a history of meteorology in Great Britain, an account of the engineering failures that led to the Challenger Space Shuttle Disaster, the histories of Perth and Dundee, the art of bridge construction, and so forth. https://www.scottishpoetrylibrary.org.uk/poem/tay-bridge-disaster C. Horne's ballad In Memory of the Tay Bridge Disaster was published as a broadside in May 1880. The Tay Bridge Disaster occurred during a violent storm on Sunday 28 December 1879, when the first Tay Rail Bridge collapsed as a train from Burntisland to Dundee passed over it, killing all aboard. The Tay Bridge Disaster And The World’s Worst Poem. So the train mov’d slowly along the Bridge of Tay. A court of Inquiry (a judicial enquiry under Section 7 of the Regulation of Railways Act 1871 "into the causes of, and circumstances attending" the accident) was immediately set up: Henry Cadogan Rothery, Commissioner of Wrecks, presided, supported by Colonel Yolland (Inspector of Railways) and William Henry Barlow, President of the Institution of Civil Engineers. It will be found that all the upper side of this column is of that description, perfectly full of air-holes and cinders. "The cotters are really wedges, and to prevent those wedges from shaking backwards their ends are split, and they are bent in that position in order to prevent them shifting up". [112], Law concluded that the bridge as designed if perfect in execution would not have failed in the way seen[113](Cochrane went further; it 'would be standing now'). Cast-on lugs tended to make unsound castings (Cochrane said he had seen examples in the bridge ruins. Which caused the tears to well up in their eyes; And in that their anticipations were only right. When it came to be known a whale was seen in the Tay,Some men began to talk and to say,We must try and catch this monster of a whale,So come on, brave boys, and never say fail. The number of deaths was actually 75, not 90 as stated in the poem. The Tay Bridge cost £300,000 to build, and used 4,000 tons of cast iron, 10 million bricks and 15,000 casks of cement. Vous êtes actuellement en train d’écouter des extraits. [4] Bouch's brother had been a director of Gilkes, and all three had been colleagues on the Stockton and Darlington 30 years previously; on Gilkes's death in January 1876, Bouch had inherited shares valued at £35,000 but also owed for a guarantee of £100,000 of Gilkes borrowings and been unable to extricate himself.[5]. Yolland and Barlow noted "there is no requirement issued by the Board of Trade respecting wind pressure, and there does not appear to be any understood rule in the engineering profession regarding wind pressure in railway structures; and we therefore recommend the Board of Trade should take such steps as may be necessary for the establishment of rules for that purpose. If visiting Dundee, I would highly recommend taking a walk to the water front. Black explained that the guard rails protecting against derailment were slightly higher than and inboard of the running rails. With a total length of 2 miles it was the longest iron bridge in the world. Which will be remember’d for a very long time. The train is heard no more. 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. [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. [126] Two marked fifth girder tie bars were produced; one indeed had 3 marks, but two of them were on the underside. It describes the moment of the disaster as:[170]. [58] When shown defects in bridge castings, he said he would not have passed the affected columns for use, nor would he have passed columns with noticeably uneven wall thickness. https://www.poetryfoundation.org/poems/45828/the-tay-bridge-disaster One witness said these advanced to the north end of the high girders with about 15 seconds between first and last;[25][note 4] the other that they were all at the north end, with less time between. [42] A joiner who had worked on the bridge from May to October 1879 also spoke of a lateral shaking, which was more alarming than the up-and-down motion, and greatest at the southern junction between the high girders and the low girders. [10] The wind speed was measured at Glasgow – 71 mph (114 km/h; 32 m/s) (averaged over an hour) – and Aberdeen, but not at Dundee. Paterson was also the engineer of the Perth General Station. A corruption of. With one lash of its ugly and mighty tail. And landed their burden at Stonehaven without fail; And when the people saw it their voices they did raise. According to Benjamin Baker "all the difficulty is in the foundations. [56] He was aware of 'burning on',[57] but the use of Beaumont egg had been hidden from him by the foreman. [114] The calculations assumed the bridge to be largely as designed, with all components in their intended position, and the ties reasonably evenly loaded. Alas! 15th August 2016. It is a beautiful view across the River Tay and there is the memorial to the disaster of the original bridge. A further passenger witness spoke of a 'prancing motion' like that felt descending from, They had never worked on a lattice girder bridge before; from disinterested recollections of the viaducts on the Stainmore line, "any of these tie-bars formed by two flat bars of iron are naturally a little out of line because they cross each other, and if they were loose and if there was any vibration it would make one bar strike against another, consequently you would have the noise of one piece of iron hitting against the other". The Tay Bridge Disaster as the incident is popularly known , was one of the worst structure failures of the time both in terms of the size and significance of the structure and also was one of the biggest disasters as it took lives of 75 people. 215–225 (Henry Abel Noble), Mins of Ev pp. Such is the impact of the incident that it is intriguing the minds of experts and common people alike till date. And loud the wind did roar; [3], The bridge was built by Hopkin Gilkes and Company, a Middlesbrough company which had worked previously with Bouch on iron viaducts. Resolved for a few days to sport and play. The terms of reference did not specify the underlying purpose of the inquiry – to prevent a repetition, to allocate blame, to apportion liability or culpability, or to establish what precisely had happened. 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. [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". Here is a flaw which extends through the thickness of the metal. for the mighty monster whale,Which has got 17 feet 4 inches from tip to tip of a tail!Which can be seen for a sixpence or a shilling,That is to say, if the people all are willing. McKean ("Battle for the North" p. 142) says the cotters were cast iron, but as will be obvious from the above they were wrought iron. Despite ongoing difficulties in its construction, the br… He had also seen this on the previous train. The bracing had failed by the lugs giving way; in nearly every case, the fracture ran through the hole. The graze marks were at 6–7 feet (1.8–2.1 m) above the rail, and 11 feet (3.4 m) above the rail and did not match carriage roof height. Pole's WP article gives a full account of his interest in music and whist but perhaps does not do full credit to his engineering credentials, for which see his obituary at, presumably design calculations had not been kept; presumably this was normal practice, since the Inquiry did not comment on this, the Board of Trade expectation was that tensile stress on wrought iron should not exceed 5 ton per square inch; this gave a margin of at least 4 against failure and about 2 against plastic deformation, p. 184 of "Useful Rules and Tables relating to Mensuration, Engineering Structures and Machines" 1866 edition (1872 edition at, His most developed example was a pane of glass in a signal cabin, In 1871 at Maryhill an NBR train running at 20–25 miles per hour (32–40 km/h) was fouled by a traveling crane on the opposite line: for details of the damage caused see, Yolland and Barlow say that if he had there would have been ample time to put in stronger ties and fastenings, which is difficult to reconcile with the weak point having been the integrally cast lugs, "From ... observations taken at Bidston of the greatest hourly velocity and of the greatest pressure on the square foot during gales between the years 1867 and 1895 inclusive, I find that the average pressure (24 readings) for an hourly run of wind at seventy miles per hour (110 km/h) was forty-five pounds per square foot (2.2 kPa). The Tay Bridge Disaster At approximately 7:15 p.m. on the stormy night of 28 December 1879, the central navigation spans of the Tay bridge collapsed into the Firth of Tay at Dundee, taking with them a train, 6 carriages and 75 souls to their fate. It happened during a violent storm on 28 December 1879. A later witness explained that this could not be checked at the foundry, as 'low girder' columns had no spigots. Then the water did descend on the men in the boats,Which wet their trousers and also their coats;But it only made them the more determined to catch the whale,But the whale shook at them his tail. The Tay Bridge Disaster as the incident is popularly known , was one of the worst structure failures of the time both in terms of the size and significance of the structure and also was one of the biggest disasters as it took lives of 75 people. The pier foundations were now constructed by sinking brick-lined wrought-iron caissons onto the riverbed, and filling these with concrete. It was suggested that the last two vehicles (the second-class carriage and a brake van) which appeared more damaged were those derailed, but (said Law) they were of less robust construction and the other carriages were not unscathed. Good Heavens! Bouch had sought expert advice on wind loading when designing a proposed rail bridge over the Firth of Forth; as a result of that advice he had made no explicit allowance for wind loading in the design of the Tay Bridge. Mins of Evidence p. 255 (H. Laws). 'Ex-Provost' Robertson[note 6] had a good view of most of the bridge from his house in Newport-on-Tay,[31] but other buildings blocked his view of the southern high girders. Oh! The number of people who died in the Tay Bridge disaster is closer to 60, rather than 75, researchers have revealed. … The piers were narrower and their cross-bracing was less extensive and robust than on previous similar designs by Bouch. Under the resident engineer there were seven subordinates including a foundry manager. The Tay Bridge disaster, Scotland, 28th December 1879 . the Tay Bridge is blown down, And a passenger train from Edinburgh, Which fill'd all the people's hearts with sorrow, And made them all for to turn pale, Because none … Perth and Kinross Council leader Murray Lyle said: “This leisure-led development has the potential to make an exciting contribution to the local economy. Whilst awaiting his report they held further hearings in Dundee (26 February – 3 March); having got it they sat at Westminster (19 April – 8 May) to consider the engineering aspects of the collapse. So they got a rope from each boat tied round his tail. [91] This advice had been endorsed by a number of eminent engineers. The bolt holes for the lugs were cast with a taper; consequently the bolt-lug contact was by the bolt thread bearing against a knife edge at the outer end of the hole. Nov 05, 2014 Richard Thomas rated it it was amazing. The bedrock lay much deeper than the trial borings had shown, and Bouch had to redesign the bridge, with fewer piers and correspondingly longer span girders. Researchers reveal the number of people who died in the Tay Bridge disaster is closer to 60, rather than 75. So small boats were launched on the silvery Tay. The Story and the Conclusions in to the cause of the Tay Rail Bridge Disaster. Design disaster . At the time of this tragedy, the Tay Bridge was the longest bridge in the world, and to this day the accident remains the worst structural disaster the UK has ever seen. "The Tay Bridge Disaster" is a poem written in 1880 by the Scottish poet William McGonagall, who has been recognized as the worst poet in history. [56] According to his predecessor, burning-on had only been carried out on temporary 'lifting columns', which were used to allow the girders to be lifted into place and were not part of the permanent bridge structure. The bridge had cost £670,000, or about £62 10s. The train into the girders came, The Tay Bridge disaster was one of the great engineering disasters of the 19th century. [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. The Tay Bridge Disaster – A reappraisal based on modern analysis methods: T. Martin and I.A. [135] They noted instead that apart from Bouch himself, Bouch's witnesses claimed/conceded that the bridge failure was due to a shock loading on lugs heavily stressed by windloading. [127] Dugald Drummond, responsible for NBR rolling stock, had examined the wheel flanges and found no 'bruises' – expected if they had smashed up chairs. Train from Edinburgh to Dundee on 28th Dec, Photographs of the damaged piers and of recovered wreckage are accessible at, Mins of Ev p. 19 (William Abercrombie Clark), Mins of Ev p. 373 (Major-General Hutchinson), Mins of Ev (pp. Are numbered with the dead. [26] A third witness had seen "a mass of fire fall from the bridge" at the north end of the high girders. Law had 'not seen anything to indicate that the carriages left the line' (before the bridge collapse)[117] nor had Cochrane[81] nor Brunlees. McKean goes on to comment on the failure of the Railway Inspectorate to comment on the hazards of hitting cast iron hard. [note 27] Law agreed with Rankine that the highest wind pressure seen in Britain was 55 psf (2.6 kPa) as the reason for designing to 200 psf (9.6 kPa) (i.e. The Tay Bridge disaster, Scotland, 28th December 1879 . The train travelling over it at the time plunged into the Tay and 75 people lost their lives. So the monster whale did sport and playAmong the innocent little fishes in the beautiful Tay,Until he was seen by some men one day,And they resolved to catch him without delay. [118] The physical evidence put to them for derailment and subsequent impact of one or more carriage with the girders was limited. [111]) Pole calculated the wind loading required to overturn the lightest carriage in the train (the second-class carriage) to be less than that needed to overturn the bridge; whereas Law – taking credit for more passengers in the carriage than Pole and for the high girders partially shielding carriages from the wind – had reached the opposite conclusion. Sir John Fowler and Sir Benjamin Baker designed the Forth Rail Bridge, built (also by Arrols) between 1883 and 1890. ‎On December 28th 1879, the Tay Bridge collapsed as a train passed over it, killing all 75 passengers on board. He doubted Rankine's pressures because he was not an experimentalist; told that the data were observations by the Regius Professor of Astronomy at Glasgow University [note 28]he doubted that the Professor had the equipment to take the readings. Law had numerous criticisms of the bridge design, some echoed by other engineers: Both Pole and Law had calculated the wind loading needed to overturn the bridge to be over 30 psf (1.4 kPa) (taking no credit for holding-down bolts fastening the windward columns to the pier masonry)[110] and concluded that a high wind should have overturned the bridge, rather than cause it to break up (Pole calculated the tension in the ties at 20 psf (0.96 kPa) windloading to be more than the 'usual margin of safety' value of 5 tons per square inch but still only half the failure tension.
