micklner Posted March 9, 2013 Share Posted March 9, 2013 It's not the first time. A similar occurence happened a few years back when a site investigation borehole went through the crown of a London Underground tunnel and caught the roof of a tube train. I can't recall when and where though. Chris Leytonstone Green Man Roundabout Link to post Share on other sites More sharing options...
RMweb Premium melmerby Posted March 10, 2013 RMweb Premium Share Posted March 10, 2013 IIRC There was an occasion, abroad somewhere, when a drilling rig in the middle of a freshwater lake broke through into an extensive salt mine underneath. The lake promptly emptied totally into the mine and AFAIK is still dry.

Southernman46 Posted March 10, 2013 Share Posted March 10, 2013 some years ago, I was involved in tamping work that broke through what appeared to be an old chimney (as far as we could work out) in the viaduct at Vauxhall station - much to the surprise of the single sex occupants of the nightclub below Link to post Share on other sites More sharing options...

Keith EDIT found it: http://www.damninteresting.com/lake-peigneur-the-swirling-vortex-of-doom/ Memory not quite up to it, actually filled with seawater! Sonething similar to this happened near leeds in 1987. An opencast coal mine at St Aidan's between Leeds and Castleford, was alongside teh River Aire. The workings, which were over 100' deep got too close to the river and one morning there was a breach in the river bank. The workings were very bis and as they started to fill with water, they managed to evacuate everone and also got the walking dragline to safety. It took several days for the mine to fill with water and during that time the section of the River Aire from Castelford to St Aidan's reversed it's flow and the River Calder flowed straight into the mine via a mile or so of the river Aire, the weir in the centre of Castleford dried up as well. Eventually things settled and the river returned to it's normal course. After discussions the river and nearby canal were diverted, a new lock was built at Lemonroyd and the mine was pumped out so that many millions of pounds worth of coal could be recovered. The dragline is still on site and preserved but the mine has now been worked out. Jamie Link to post Share on other sites More sharing options...
Ozexpatriate Posted March 12, 2013 Share Posted March 12, 2013 60 miles!!!!! Chicago was quite the bustling place at the turn of the 20th century. By the time of the 'Great Leak' in 1992 most Chicagoans had forgotten the tunnel railway existed. I quite like the idea of Marshall Field's or Carson Pirie Scott (the grand department stores) shipping merchandise through the tunnels. Link to post Share on other sites More sharing options...

roythebus Posted March 15, 2013 Share Posted March 15, 2013 There's a more accurate report on the Central Line drill on the district Dave website. My mate Dean Sullivan was area manager for that part of the Central Line at the time and had to deal with the aftermath. I had a similar incident on the Waterloo and City in about 1986, not with a drill but with a cable which suddenly appeared at the yard end of the "arriva" platform at Waterloo. I'd just arrived from Bank when I noticed a "something" looping down from the top of the tunnel, onto the track and back to the top of the tunnel. I daren't run my train under it, so the job stopped, power off etc whjile it was investigated. It turned out contractors were installing cable TV cables in troughing from the roadway above and wondered where their cable had gone to!! There was a loop of about 50m of quite thick cable to be retrieved. Link to post Share on other sites More sharing options...

Talltim Posted February 13, 2014 Share Posted February 13, 2014 I want this job London Underground staff also walk the routes of tunnels at street level to look for evidence of development work (eg demolition and site activity) which may not have been identified by other processes. The streets above subsurface tunnels (eg the Metropolitan, District and Circle Lines) are walked every four weeks, and above deep tube routes every eight weeks.

Pugsley Posted February 13, 2014 Share Posted February 13, 2014 Report into this one is out: http://www.raib.gov.uk/publications/investigation_reports/reports_2014/report032014.cfm Out of all that, this paragraph is the most disturbing: The search provider has stated that it did not offer a Network Rail search because it did not believe that Network Rail supplied a bespoke conveyancing search service to define rail infrastructure How on earth could a 'specialist provider', who would be doing this kind of activity day in, day out, make an error like that?
