New Longest Czech Railway Tunnel Gets Topologically Completed

This video of a "walkthrough" was added on September 10th, 2016.

I possess got been next the structure of the novel railway "Tunnel Ejpovice" (Kyšice-Chlum) nigh Pilsen really carefully. An hr ago, nosotros could finally witness the minute when the impressive German linguistic communication machine Herrenknecht TBM S-799 nicknamed Viktorie (probably afterward the best soccer squad inwards Czechia, FC Viktoria Pilsen) – whose sibling was late used somewhere underneath London every bit good as well as they seemed to live more proud nearly it than nosotros are – finally changed the topology of the Pilsner region.

As nosotros liked exercise scream when nosotros were drilling the holes for the ethernet wires for the Internet at our educatee hostels inwards Prague inwards 1993, "penetration"! I've genuinely taught my swain workers to scream "orgasm" but let's non live picky.



There volition live 2 independent tunnels. The 2d opening of the initiatory off tube, i.e. the Southern tunnel, has finally emerged beneath the Chlum Hill inwards Pilsen, i mile from our home. (Chlum itself meant a "hill covered past times forest" inwards archaic Czech.) Nice catering including 3 spectacles of champagne, a beer, a lunch, as well as 3 pies were prepared for the relevant people – Metrostav workers, directors, mayors as well as other of import municipal politicians, as well as high position out energy physics bloggers. The EU that has contributed to this $160 1000000 projection has thus earned a little unimportant addition inwards my statistics. ;-)




The tunnel is 4.15 kilometers long – much longer than 1.75 km, the length of the longest operational Czech railway tunnel at this moment. The TBM gadget (tunnel dull machine) volition live drawn dorsum to the beginning hole inwards the hamlet of Kyšice (which I also monitored lastly twelvemonth when the structure was getting started) as well as Viktorie volition dig the second, Northern tunnel from the same direction, hopefully to a greater extent than speedily than the initiatory off subway scheme because they are already experienced.




It takes some xc minutes for the fastest trains to larn from the Pilsen master copy develop station to the Prague master copy develop station. The awkward detour around the Chlum Hill inwards Pilsen is the master copy (but non only) argue why the trains are then much slower than the cars as well as buses. Regular charabanc lines alone necessitate fifty minutes to larn from the middle of Pilsen to the Western suburbs of Prague. After all the $1.2 billion improvements of the Prague-Pilsen-Cheb railway tracks as well as the speed is increased, the fourth dimension needed to larn from Pilsen to Prague should driblet almost past times 50%.

(YouTube allows you lot to possess got a develop from Pilsen to Prague-Smíchov for free. I've taken that develop nearly 200+200 times inwards my life. If you lot haven't, you're recommended to lookout adult man this highly entertaining 80-minute painting demo LOL.)



I possess got lots of photographs as well as brusk videos I took but this video shows pretty much the same things nosotros could run into as well as mortal could speedily exercise a to a greater extent than professional person cinema than I could. ;-) See also iDNES.cz amongst 2 videos, denik.cz, novinky.cz, Qap, as well as CN.cz. Or the 2010 eight-minute visualization of the modernization of the railway tracks betwixt Pilsen as well as Rokycany.

It's in all probability non infinitely hard but I am impressed how inexpensive the tunnels are as well as how accurately they were able to hitting the target. The accuracy is for certain much improve than i meter. There should live some extra consequence on Sabbatum – I was told that in that location could live some projection stunt, mayhap a pocket-sized version of the Prague Astronomical Clock 600th anniversary show.

H5N1 previous weblog postal service was dedicated to the Blanka Tunnel for cars inwards Prague.

The speed of the structure seems to live identical to that inwards the LEP-LHC tunnel at CERN – below 10 meters a 24-hour interval inwards average. The earthworks for the LEP-LHC tunnel was done past times 3 TBMs, then it's nearly nine km per TBM, as well as it took 3 years (1985-1988). That's pretty much the same speed every bit 1.35 years for 4.15 kilometers of the Southern tunnel that but arrived to Pilsen. Note that the LHC tunnel was Europe's largest civil applied scientific discipline projection earlier the Channel Tunnel was built.



Colliders come upward as well as go, the tunnel stays. In 2000 when this vocal was shot, the collider inwards the tunnel was LEP piece the LHC was the cite of the band (Les Horribles Cernettes). Today, the collider inwards the tunnel is the LHC as well as the cernette is a 750 GeV particle that the collider may possess got discovered but nosotros volition alone know when the already-processed information are publicized. By extrapolation, inwards 2032, the collider inwards the tunnel volition live called the Cernette as well as the string excitations it volition uncovering volition live named LEP.

The latest portions of the Pilsner tunnel took much to a greater extent than fourth dimension than expected. The stone nether the Chlum Hill was a rather hard spilite because Chlum used to live a volcano, nosotros were told. The knives of the TBM had to live replaced twice every bit oft here. The diameter of the TBM is 9.9 meters as well as during the structure of the 4.1 km cylinder, it had to rotate 450,000 times.
