PART OF RAILWAY HISTORY: THE CONSTRUCTION OF THE THREE LARGE ALPINE TUNNELS IN SWITZERLAND

AUS DER EISENBAHNGESCHICHTE: VOM BAU DER DREI GROSSEN ALPENTUNNEL IN DER SCHWEIZ

THE CONSTRUCTION OF THE 15 KM LONG GOTTHARD TUNNEL WAS STARTED IN 1872 AFTER A GOVERNMENT AGREEMENT BETWEEN SWITZERLAND, ITALY AND GERMANY. AFTER 9 YEARS THE TUNNEL WAS IN OPERATION. REGULAR WATER INRUSH AND TEMPERATURES UP TO 33 DEGREES C IN THE TUNNEL MADE WORK DIFFICULT. THE LONG LOETSCHBERG TUNNEL WAS BUILT BETWEEN 1906 AND 1912. HERE TOO PROBLEMS WERE CAUSED BY REGULAR INRUSH OF FILL AND WATER WHICH RESULTED IN MODIFICATIONS TO THE ALIGNMENT IN SOME PLACES. THE SIMPLON TUNNEL HAS TWO PARALLEL, SINGLE-LANED TUNNEL TUBES; IT WAS BUILT IN 1912/1922 AND IT IS 19.823 KM LONG.
