The Simplon Tunnel (Simplontunnel, Traforo del Sempione or Galleria del Sempione) is a railway tunnel on the Simplon railway that connects Brig, Switzerland and Domodossola, Italy, through the Alps, providing a shortcut under the Simplon Pass route. It is straight except for short curves at either end. [1] It consists of two single-track tunnels built nearly 15 years apart. The first to be opened is 19,803 m (64,970 ft) long; the second is 19,824 m (65,039 ft) long, making it the longest railway tunnel in the world for most of the twentieth century, from 1906 until 1982, when the Daishimizu Tunnel opened.
Culminating at a height of only 705 m (2,313 ft) above sea level, the Simplon Tunnel was also the lowest direct Alpine crossing for 110 years, until the opening of the Gotthard Base Tunnel in 2016. The tunnel has a maximum rock overlay of approximately 2,150 m (7,050 ft), [2] also a world record at the time. Temperatures up to 56 °C (133 °F) have been measured inside the tunnel. [3]
Work on the first tube of the Simplon Tunnel commenced in 1898. The Italian king Victor Emmanuel III of Italy and the president of the Swiss Confederation (presiding the Federal Council of Switzerland for that year) Ludwig Forrer opened the tunnel at Brig on 19 May 1906. [4] The builders of the tunnel were Hermann Häustler and Hugo von Kager. Work on the second tube of the tunnel started in 1912 and it was opened in 1921.
Shortly after the opening of the first railway in Switzerland, each region began to favour a separate north–south link through the Alps towards Italy. Eastern Switzerland supported a line through the Splügen Pass or the Lukmanier Pass, Central Switzerland and Zürich favoured the Gotthard Pass and Western Switzerland supported the Simplon route.
In 1871, the first line was completed through the Alps, connecting Italy and France with the Fréjus Rail Tunnel.
The Compagnie de la Ligne d'Italie was founded in 1856 to build a connection between Romandy and Italy through the Canton of Valais and the Simplon. On 1 June 1874, it was taken over by the Simplon Company (French: Compagnie du Simplon, S), which was created to promote the project. This merged in 1881 with the company Western Swiss Railways (French: Chemins de Fer de la Suisse Occidentale, SO) to create the Western Switzerland–Simplon Company (French: Compagnie de la Suisse Occidentale et du Simplon, SOS). The French financiers of the SOS were able to secure finance for the tunnel in 1886. The company considered 31 proposals and selected one that involved the construction of a tunnel from Glis to Gondo, which would have been fully in Switzerland. From Gondo it would have continued on a ramp through the Divedro valley down to Domodossola.
At a Swiss-Italian conference held in July 1889, it was agreed, however, to build a nearly 20-kilometre long (12 mi) base tunnel through the territory of both states. In order to secure credit for the tunnel, the SOS joined with the Jura–Bern–Luzern Railway to create the Jura–Simplon Railway (French: Compagnie du Jura–Simplon, SOS).
The participation of the Swiss government led to the signing of a treaty with Italy on 25 November 1895 concerning the construction and operation of a railway through the Simplon from Brig to Domodossola by the Jura–Simplon Railway. The route of the tunnel was determined by military considerations so that the state border between the two countries was in the middle of the tunnel, allowing either country to block the tunnel in the event of war.
On 1 May 1903, the Jura-Simplon Railway was nationalized and integrated into the network of the Swiss Federal Railways (SBB), which completed the construction of the tunnel.
The construction of the tunnel was carried out by the Hamburg engineering company Brandt & Brandau, of Karl Brandau and Alfred Brandt . On average, 3,000 people a day worked on the site. They were mostly Italians, who suffered under very poor working conditions: 67 workers were killed in accidents; many died later of diseases. During the work, there were strikes, which led to the intervention of vigilantes and the Swiss army.
With up to 2,150 m (7,054 ft) of rock over the tunnel, temperatures of up to 42 °C (108 °F) were expected and a new building method was developed. In addition to the single-line main tunnel, a parallel tunnel was built, with the tunnel centres separated by 17 m (56 ft), through which pipes supplied fresh air to the builders in the main tunnel. It was envisaged that the parallel tunnel could be upgraded to a second running tunnel when required. The first Simplon Tunnel (19,803 m (64,970 ft) in length) was built almost straight, with only short curves at the two tunnel portals.
On 24 February 1905, the two halves of the tunnel came together. They were out of alignment by only 202 mm (8 in) horizontally and 87 mm (3.4 in) vertically. Construction time was 7+1⁄2 years, rather than 5+1⁄2 years, due to problems such as water inflows and strikes.
Operations commenced through the tunnel on 19 May 1906. Because of its length among other things, it has operated with electric traction rather than steam from the beginning. The official decision to use electricity was made only half a year before its opening by the then-still-new SBB. Brown, Boveri & Cie (BBC) were commissioned to carry out the electrification. They decided in 1904 to use the three-phase system being introduced in Italy, with a three-phase power supply of 3,400 volts at 15.8 Hz [5] using two overhead wires with the track acting as the third conductor. BBC had no electric locomotives and initially acquired three locomotives built for the Ferrovia della Valtellina—the owner of the lines from Colico to Chiavenna and Tirano, which had been electrified with this system in 1901 and 1902 [5] —from their owner, the Rete Adriatica (Adriatic Network) railway company. These three locomotives (which became FS Class E.360) hauled all traffic through the tunnel until 1908. On 2 March 1930, the Simplon tunnel was converted to 15 kV, 16.7 Hz AC (single-phase).
Between 1912 and 1921, the 19,823-metre long (65,036 ft) second tube, known as Simplon II, was built. On 7 January 1922 the northern section from the north portal to the 500-metre long (1,640 ft) passing loop in the middle of the tunnel was brought into operation, followed on 16 October 1922 by the southern section from the passing loop to the south portal.
During the Second World War, on both sides of the border, there were preparations for the possible detonation of the tunnels. In Italy, the German army planned, as part of its 1945 withdrawal, to blow up the tunnel, but was thwarted by Italian partisans with the help of two Swiss officials and Austrian deserters.
There is a car-carrying shuttle between Brig and Iselle di Trasquera, which provides a 20-minute train journey as an alternative to driving over the Simplon Pass. The service began on 1 December 1959. As roads over the Simplon Pass steadily improved throughout the 1970s and 1980s the tunnel's shuttle schedule was cut back, then ended altogether on 3 January 1993. Almost twelve years later, on 12 December 2004, the car shuttle service began again and now runs about every 90 minutes.
In the early 1990s, a project to implement the rolling highway system of piggyback operations for transalpine freight on the Lötschberg–Simplon axis was implemented. Such operations were possible under the previous profile of the Simplon Tunnel, but capacity would have been heavily restricted because its height was too low to carry trucks at the permitted maximum corner height of four metres (13 ft 1+1⁄2 in). The clearance in the tunnel was therefore increased by lowering the rail trackbed. This work began in 1995 and lasted eight years. At the same time, the tunnel vault was rehabilitated, while the drainage tunnel was rebuilt. A total of 200,000 m3 (260,000 cu yd) of rock was removed with pneumatic breakers.
In addition, a new railway electrification system was installed using overhead electric rail instead of the tensioned cable normally used for overhead electrification so that the required 4.90-metre (16 ft 7⁄8 in) height clearance could be achieved. In the late 1980s, a one kilometre (0.62 mi) long overhead electric rail had been tested at 160 km/h (99 mph). Before this experiment, trains running under overhead electric rails in Switzerland had been limited to 110 km/h (68 mph) and internationally to 80 km/h (50 mph). [6]
Restricted rail operations were maintained during the entire construction period.
In order to expand the Lötschberg-Simplon axis into a powerful transit axis, various extensions to the access lines (from Bern and Lausanne in the north and from Novara and Milan in the south) have been made in recent years and decades. The largest projects have dealt with the northern access from Basel-Bern via Lötschberg. Between 1976 and 2007 there were three major transformations. First, the remaining single-track line between Spiez and Brig was dualled. Later, adjustments were made to the tunnel profile for piggyback traffic; in places only widening one track was possible. Finally, the Lötschberg Base Tunnel partially opened in 2007, although the new tunnel still has a 21-kilometre (13 mile) single-track section; this was done in order to save costs for the construction of the longer Gotthard Base Tunnel, which was completed in 2016.
Clearances were also raised for the piggyback traffic on the Italian side as well on the Simplon southern approach. Here, too, for financial reasons, at times only one line was cleared for the rolling highway. South of Domodossola, the single line to Novara via Lake Orta was electrified and modernized.
The classic approach to the Simplon from Paris and Lausanne—less important for today's transit traffic—was upgraded in the context of a nationwide rail upgrading project, Rail 2000, between 1985 and 2004. Further adjustments are proposed. In November 2004, the 7-kilometre long (4.3 mi) new line between Salgesch and Leuk in the Rhone Valley was completed to replace the last single-track bottleneck on the route. Under the ZEB ("Future rail development projects") package, the maximum speed on the long straight sections of the Rhone valley lines will be increased from 160 to 200 km/h (99 to 124 mph).
On 9 June 2011, a 300 m (984 ft) section of the Simplon II tunnel's roof was seriously damaged when a northbound BLS freight train caught fire and stopped 3 km (1.9 mi) into the tunnel. The temperature exceeded 800 °C (1,470 °F) and took more than two weeks to cool back to normal. By agreement all repairs to the tunnels are the responsibility of the SBB, which expected to reopen the tunnel in December 2011. The other tunnel remained in service. [7]
Repair work was completed in November 2011. [8]
In the 1957 novel From Russia, with Love by Ian Fleming, protagonist James Bond fights his enemy, SMERSH agent Donovan Grant, eventually killing him, while passing through the Simplon Tunnel on the Orient Express .
In Against the Day by Thomas Pynchon, Reef Traverse, one of the novel's characters, works on the construction of the Simplon Tunnel. [9]
In the novel "The Couloir" by Richard Manichello, the Canton Valais is a major geographical setting for action and scenes. especially the Val de Bagnes. Brig and the Simplon Pass & Tunnel play an important role in the main plot, moving characters in and out of Western Swiss locations or over the Pennine Alps for various intrigues and subplots involving action that traverses Swiss and Italian story settings.
The Bern-Lötschberg-Simplon-Bahn (BLS), known between 1997 and 2006 as the BLS Lötschbergbahn, was a Swiss railway company. In 2006 the company merged with Regionalverkehr Mittelland AG to form a new company called BLS AG.
The Swiss rail network is noteworthy for its density, its coordination between services, its integration with other modes of transport, timeliness and a thriving domestic and trans-Alp freight system. It is made necessary by strong regulations on truck transport, and is enabled by properly coordinated intermodal logistics.
Domodossola is a city and comune (municipality) in the Province of Verbano-Cusio-Ossola, in the region of Piedmont, northern Italy. It was also known as Oscela, Oscella, Oscella dei Leponzi, Ossolo, Ossola Lepontiorum, and Domo d'Ossola. The Peruvian aviation pioneer, Jorge Chávez died here in 1910 in an airplane crash.
The Simplon Pass is a high mountain pass between the Pennine Alps and the Lepontine Alps in Switzerland. It connects Brig in the canton of Valais with Domodossola in Piedmont (Italy). The pass itself and the villages on each side of it, such as Gondo, are in Switzerland. The Simplon Tunnel was built beneath the vicinity of the pass in the early 20th century to carry rail traffic between the two countries.
The New Railway Link through the Alps, is a Swiss construction project for faster north–south rail links across the Swiss Alps. It consists of two axes with several improvements along these rails including three new base tunnels several hundred metres below the existing apex tunnels, the 57-kilometre (35 mi) Gotthard Base Tunnel, the 35-kilometre (22 mi) Lötschberg Base Tunnel, and the 15-kilometre (9.3 mi) Ceneri Base Tunnel. Swiss Federal Railways subsidiary AlpTransit Gotthard AG and BLS AG subsidiary BLS Alp Transit AG were founded for this project and built the tunnels.
The Gotthard Pass or St. Gotthard Pass at 2,106 m (6,909 ft) is a mountain pass in the Alps traversing the Saint-Gotthard Massif and connecting northern Switzerland with southern Switzerland. The pass lies between Airolo in the Italian-speaking canton of Ticino, and Andermatt in the German-speaking canton of Uri, and connects further Bellinzona and Lugano to Lucerne, Basel, and Zürich. The Gotthard Pass lies at the heart of the Gotthard, a major transport axis of Europe, and it is crossed by three traffic tunnels, each being the world's longest at the time of their construction: the Gotthard Rail Tunnel (1882), the Gotthard Road Tunnel (1980) and the Gotthard Base Tunnel (2016). With the Lötschberg to the west, the Gotthard is one of the two main north-south routes through the Swiss Alps.
The Lötschberg Tunnel is a 14.612 km (9.079 mi) long railway tunnel on the Lötschberg Line, which connects Spiez and Brig at the northern end of the Simplon Tunnel cutting through the Bernese Alps of Switzerland. Its ends are at the towns of Kandersteg in the canton of Bern and Goppenstein in the canton of Valais. The top elevation of the tunnel is 1,240 m (4,070 ft) above sea level, this is the highest point of the main Swiss railway network.
The Lötschberg is an Alpine mountain massif, usually associated with a major, historically important transit axis of the Alps in Switzerland with, at its core, the Lötschen Pass. The mountain pass, which culminates at nearly 2,700 metres above sea level, are part of the eastern Bernese Alps, whose main crest straddles the border between the cantons of Bern and Valais. The valleys concerned by the Lötschberg are those of the Kander in the Berner Oberland, with Kandersteg at the head of it, and a secluded side-valley of the Upper Valais, the Lötschental, with Ferden at the valley's entrance and at the bottom of the pass.
The Domodossola–Milan railway line is a major Italian railway route and an important part of the European rail network. It is one of Italy's busiest lines for both passenger and freight trains. The line connects Milan and Domodossola with Brig, an important Swiss railway junction, via the Simplon Tunnel. Direct passenger trains ran from Brig to Paris and Brussels and Luxembourg via Basel. The line runs through lower Varese Province, the valley of Ossola and along the shore of Lake Maggiore.
The Lötschberg line is a railway in Switzerland, connecting Spiez in the canton of Bern with Brig in the canton of Valais. It crosses the Bernese Alps, from the Bernese Oberland to Upper Valais, through the Lötschberg Tunnel in the middle of the line. Together with the Simplon Tunnel south of Brig, it constitutes one of the major railways through the Alps and an important north-south axis in Europe. The Lötschberg axis is backed by the lower and longer Lötschberg Base Tunnel, part of the New Railway Links through the Alps project.
The Western Switzerland Railways, were initially a joint operation of three Swiss railway companies, but these companies merged on 1 January 1872. The company was called the Western Switzerland–Simplon Railways from 28 June 1881. The SOS merged with the Bernese Jura Railways to form the Jura–Simplon Railways on 1 January 1890.
The Jura–Simplon Railways (JS), was a railway company that was formed in 1890. It was nationalised in 1903 as the largest railway company in Switzerland and integrated into the Swiss Federal Railways (SBB).
The construction and operation of Swiss railways during the 19th century was carried out by private railways. The first internal line was a 16 km line opened from Zürich to Baden in 1847. By 1860 railways connected western and northeastern Switzerland. The first Alpine railway to be opened was under the Gotthard Pass in 1882. A second alpine line was opened under the Simplon Pass in 1906.
A car shuttle train, or (sometimes) car-carrying train, is a shuttle train used to transport accompanied cars (automobiles), and usually also bicycles and other types of road vehicles, for a relatively short distance.
Visp railway station is a junction station at Visp, in the canton of Valais, Switzerland. It has a modern station building completed in 2007, and is served by two standard gauge lines and a metre gauge line.
Brig railway station is an important railway junction in the municipality of Brig-Glis, in the Canton of Valais, Switzerland. Opened in 1878, it is adjacent to the northern portal of the Simplon Tunnel and is served by two standard gauge lines. Another two metre gauge lines serve the physically adjacent Brig Bahnhofplatz railway station.
Iselle di Trasquera railway station serves the village of Iselle and municipality of Trasquera, in the region of Piedmont, northwestern Italy. Opened in 1906, the station is at the southern portal of the Simplon tunnel, on the Simplon line, between Brig, Switzerland and Domodossola, Italy. It is also the border station between Italy and Switzerland. All rail services to and from the station are operated by BLS AG, a Swiss company.
The Simplon Railway is a line that links Lausanne in Switzerland and Domodossola in Italy, via Brig. The 20 km (12 mi)-long Simplon Tunnel is a major part of it. The line between Lausanne and Vallorbe is sometimes considered to form part of the line, making it 233 km (145 mi) long.
The Bern–Thun railway line is a double-tracked, electrified railway line that runs through the Aare valley in the Swiss canton of Bern. It is part of the Lötschberg-Simplon axis between Germany and Italy. It was opened in 1859 by the Swiss Central Railway.
The Compagnie de la Ligne d’Italie, or Ligne d’Italie for short, was a former Swiss railway company that established in 1859. In 1874, the Ligne d'Italie became part of the Compagnie du Simplon. The Compagnie du Simplon, Ligne du Simplon or Simplon for short, merged into the Western Swiss Railways in 1881.
