LONDON RAILWAY WONDER.

SIX TUBE TUNNELS THAT LEAP OR DIVE.

By means of one of the,most wonderful engineering feats of recent years—a junction of six tunnels on the‘Underground Railway between Euston and London* JT' 11 ', 6 Cit y a *d South London Railway has been linked up form .Hamstead tube. The tunnels iorm their junction in a unique way oH,X aU t “ l rf, aud . passin S beneath each - There is no other piece of engineering like it in the world,” an Underground official told a Daily Mail reporter. “It was an extraordinarily intricate task—but it had to be done, so that through services might be run right trom Hendon or Highgate to Moorgate street, in the city, and later on to Clapham. The ordinary way of making a junction is to make tunnels converge at a flat point. Had this plan been followed, however, it would have mount that trains would alwavs have been held up to allow others to pass, and a great deal of time would have been wasted. As it is, six trains lull be able to pass at the same time by means of these new tunnels. On Easter Sunday, when the junction was hrst in full working order, more than 100 trains an hour ran to and from the city and Hendon and Highgate. If necessary, we could run 160 on the ‘through’ route. The direct service should prove a great boon to manv thousands of people who travel between these points, and who have had to change several times to reach their destination.” He, added that the Underground Railway were very proud of the new junction. “Much of the work had to be done while trains were running ” he said, but although 17 connections had to be made between the new and the old tunnels, everything was carried out without a hitch and with mathematical precision.” It is estimated the full extension of the Hampstead Tube from Hendon to Edgware will be accomplished by July.
