|} The Olten–Lausanne railway line is one of the major railway lines of Switzerland, running between the major rail hub of Olten—where lines from Zurich, Basel, Bern, Lucerne and Neuchâtel come together—the Swiss capital of Bern and the city of Lausanne. It is known as the Mittellandlinie ("midland line") in German. The first part of the line was opened in 1856 and the original line was completed on 4 September 1862. The line was built by the Swiss Central Railway, which was taken over by the Swiss Federal Railways on its establishment in 1902. Several important upgrades have been implemented on this line since 1981. The Born line was opened in 1981 to bypass a congested section of line around Aarburg Oftringen station and the longer Grauholz line, including the tunnel Grauholz Tunnel, was opened in 1995. This was extended on 12 December 2004, when the first major high-speed Mattstetten–Rothrist line was opened, although it is limited to 200 km/h. This line is notable for having the heaviest traffic operating under the European Train Control System so far. ==History== The oldest section of the line opened on 9 June 1856 from Olten to Aarburg-Oftringen as part of a line built by the Swiss Central Railway (German: ''Schweizerische Centralbahn'') between Aarau, Olten, Aarburg and Emmenbrücke (near Lucerne). On 16 March 1857 the company opened the section from Aarburg-Oftringen to Herzogenbuchsee; three months later a branch line to Solothurn to the Jura foot line was opened to traffic. Only 15 days later, on 16 June 1857, this was followed by the extension of the line from Herzogenbuchsee to Burgdorf and Zollikofen to the edge of the city of Bern at Wylerfeld. Since the railway bridge over the Aare river not yet built, a temporary station was established at Wylerfeld and for over a year, travellers were taken by coach from Wylerfeld to the city. Also a pedestrian link was opened at that time via the Altenbergsteg bridge below the site of the Kornhaus road bridge (which was completed in 1898). Finally on 15 November 1858, the Aare Bridge (known as the ''Rote Brücke'', German for "red bridge") because of its red lead rust-proof paint) was completed and the first train crossed the bridge and ran into Bern. Since the station building was still under construction, a temporary train shed was built. On 1 May 1860, the permanent Bern station was opened. The Canton of Fribourg delayed the construction of the line from Bern to Lausanne in a bid to have it run through the city of Fribourg rather than on flatter land further west; in 1857 the Swiss government, the canton of Vaud and the West Switzerland Company gave in, allowing construction to commence on the line. On 2 July 1860, the line opened from Bern to the northern end of the 352 metre-long Grandfey Viaduct being built over the Saane river in Balliswil, near Fribourg. The Bern–Thörishaus section was built by the ''Swiss Central Railway'' and the Thörishaus–Ballenwil section by the Lausanne–Fribourg–Bern Railway ((フランス語:Chemin de fer Lausanne-Fribourg-Berne), LFB). It took another two years of hard work to complete the Grandfey Viaduct before the line from Fribourg and Lausanne was open to traffic. From 4 September 1862 two rail tracks were consistently open to traffic from Olten to Lausanne. The line was taken over by the Swiss Federal Railways on its establishment in 1902. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Olten–Lausanne railway line」の詳細全文を読む スポンサード リンク
