The Gotthard railway (German: Gotthardbahn; Italian: Ferrovia del Gottardo) is the Swiss trans-alpine railway line from northern Switzerland to the canton of Ticino. The line forms a major part of an important international railway link between northern and southern Europe, especially on the Rotterdam-Basel-Genoa corridor. The Gotthard Railway Company (German: Gotthardbahn-Gesellschaft) was the former private railway company that financed the construction of and originally operated that line.

The railway comprises an international main line through Switzerland from Basel (French Bâle) or Zürich to Immensee to Chiasso, together with branches, from Immensee to Lucerne and Rotkreuz, from Arth-Goldau to Zug, and from Bellinzona to Chiasso, via Locarno and Luino. The main line, second highest standard railway in Switzerland, penetrates the Alps using the Gotthard Tunnel at 1,151 metres (3,776 ft) above sea level. The line then descends as far as Bellinzona, at 241 metres (791 ft) above sea level, before climbing again to the pass of Monte Ceneri, on the way to Lugano and Chiasso. The extreme differences in altitude necessitate the use of long ramped approaches on each side, together with seven spirals.

Construction of the line started in 1872, with some lowland sections opening by 1875. The full line opened in 1882, following the completion of the Gotthard Tunnel. The line was incorporated into the Swiss Federal Railways in 1909 and electrified in 1922. The line has 36 tunnels totaling 31,216 meters.^{[citation needed]}

The approaches to the existing tunnel continue to restrict speed and capacity on this important international route, and in 1992 it was decided to build a new lower level route on the Gotthard axis as part of the NRLA project. This route involves the construction of the new Gotthard Base Tunnel and Ceneri Base Tunnel. The Gotthard Base Tunnel has been completed and was integrated with the existing route in 2016, while the Ceneri Base Tunnel was opened in 2020.

History

Conception

By the early 1870s, northern Switzerland had a significant network of railways, with links to the adjoining railways of Germany and France. To the west, a line had reached Brig, in the upper Rhone valley, from Lausanne. In the central north, lines linked Olten, Lucerne, Zug and Zürich. However, no line had yet reached through the Alps to southern Switzerland or the border with Italy. All north-to-south rail traffic had to pass either to the west or east of Switzerland through the Mont-Cenis, Semmering or Brenner railways.^[4]

A north-south route through Switzerland had been discussed as far back as 1848. An international conference in Bern in 1869 had decided that the best route would be via the valleys of the rivers Reuss and Ticino, linked by a tunnel under the Gotthard Pass. The selected route was an ancient one that pilgrims and traders had used since at least the 13th century.^[4][5]

Treaties for the construction of the line were made with the Kingdom of Italy, in 1869, and the German Empire, in 1871. The Gotthard Railway Company was incorporated in Lucerne in 1871. To the overall costs of CHF 238 million (in 1869/71) the Italian government eventually contributed CHF 58 million (£2.25 million),^[4] with Germany contributing CHF 30 million (£1.25 million).^[4][6]

Construction and opening

Construction of the Gotthard railway started in 1872, and the first lowland sections from Biasca to Locarno and Lugano to Chiasso were opened by 1874.

The whole line was inaugurated with festivities in Lucerne and Chiasso from 21 May to 25 May 1882. Scheduled operations started on 1 June. At the time, the 15,003-metre-long (49,222 ft) Gotthard Rail Tunnel was the world's longest rail tunnel (seconded by the Simplon Tunnel in 1906). Soon after construction, the army secured the line with fortresses (for instance, above Airolo, and at Biasca) and ways to block the tunnel in case of an invasion (among others, an artificial landslide to block the southern tunnel entrance).

At the same time, the Aargauische Südbahn completed the section from Rotkreuz to Immensee,^{[citation needed]} which provided a rail link from Aarau. The additional feeder lines from Lucerne to Immensee, and from Zug to Arth-Goldau were completed in 1887.

Early railway operations

The Gotthard railway timetable from 1899

The Gotthard Railway graphic timetable contains a great variety of information with regards to material and especially operational aspects in the year 1899, 17 years after the inauguration of the Gotthard tunnel and completion of the railway. The map key and captions to each column are to be found at the top of the page. Leading from left to right information is given on the location of each station's elevation in relation to sea level, the longitudinal profile, signal lights, tunnels and their length, for each route section on southbound journeys the greatest gradient, distances, employed telegraphs and their networking, signal bells and their connection, telephones, block stations, track layout of the respective station and their equipment, total usable length of the remaining tracks, the longest side track, station names and distances between them, distance to point of origin and between main stations. Departure and arrival times are displayed within the graphic timetable.

Information can be drawn as to the tunnel's vertex which lies at 1154.5 meters above sea level and the fact that the tunnel does not run in a straight line but rather in a slope down from either side of its vertex. The tunnel was designed in such a way that inflowing water would be able to drain. From the railway station of Göschenen to the tunnel's vertex the train lines ascend at an angle of 6 ‰ and descend at 2 ‰ from vertex to the village of Airolo. The tunnel's length is indicated to be 14,998 meters, its vertex being at kilometre 80. The old Gotthard railways' distances were measured from the town of Immensee, as clearly indicated on the graphic timetable.

Electrical Telegraphs and signal bells are listed on the distance column's right and a detailed description thereof is to be found in the chapters The Gotthard railway Telegraph Network and The Gotthard railway Signal Bells.

The track layout of each station shows that in 1899 the Gotthard railway ran on double-tracks from the villages of Flüelen to Giubiasco. Facing north the picture on the right shows the watchman's house at the Mondascia bridge depicts the double-tracks and advance signal to the entry signal before Biasca (at 132.5 km), mentioned in the timetable. The next picture on the right shows the Pianotondo viaduct and the Pianotono-spiral tunnel's upper gate with its watchman's house, which came into use during the days of the double-track steam service, roughly at the time of the graphic timetable's validity.

The graphic timetable sees two tracks running southwards from Giubiasco station. One is signposted "Chiasso", the other "Luino/Locarno". From this point onwards the railway runs on single tracks. Giubiasco's neighbouring stations to the south, Rivera-Bironico and Cadenazzo, are all on single tracks. At each underpass on the Ceneri section it is clearly visible to this day that these were built at greatly different points in time. The Giubiasco-Al Sasso^[8] and Al Sasso-Rivera sections were equipped with double-tracks in 1922 and 1934 respectively.

The graphic timetable is a two-dimensional image of the train journeys. Time is displayed horizontally from midnight XII o'clock to midnight XII o'clock. The stations along the journey, from Zug and Lucerne to Chiasso, Locarno and Luino are displayed vertically. The first scheduled train, an express train with 1st, 2nd and 3rd class carriages, leaves Bellinzona at 03:17. The train with the number 55 is powered by a steam locomotive and, according to the timetable, does not make a scheduled stop at Giubiasco, Rivera-Bironico and Taverne. Arrival at Lugano is scheduled at 04:09, from where it leaves again at 04:14. In 1899 the entire train journey from Bellinzona to Lugano was scheduled to be 52 minutes. Today (2017), the same journey on one of the EC trains takes 27 minutes. The illustrations shows that between Giubiasco and Rivera Bironico trains do not pass each other as in 1899 this was, as mentioned in the paragraph above, a single track line. This information can thus be drawn form both, the stations' track layout and the graphic timetable. Also visible on the graphic timetable is the fact that between Osogna and Biasca, trains however do pass each other along their journeys, it being a double-track line. Further, the Arth-Rigi-Bahn's trains (nowadays Rigi Railways), are also listed in the Gotthard railways' timetable. The timetable's scale is 15mm/hour horizontally and 1.75mm/km vertically.

The Gotthard railway telegraph network

To coordinate trains, the Gotthard railway used a telegraph-network, which linked up all railway stations on the entire line from Luzern to Chiasso, Locarno and Luino. This network is pointed out on the left hand side of the graphic timetable dated 1899. The telegraphs for every railway station shown on the timetable are marked with a black dot. As a detailed section from the timetable shows, the Biasca station used four telegraphs at that time. One of those telegraphs linked all stations from Biasca to Bellinzona. Whatever message was tapped out on this telegraph (sent by morse code), was transmitted to all stations up to Bellinzona. A second telegraph linked all stations from Biasca to Göschenen. What was tapped out on the third telegraph, reached only the railway stations Bellinzona, Faido, Airolo, Göschenen, Wassen and Erstfeld. The fourth telegraph was for long distances. Messages transmitted from there reached Bellinzona, Airolo, Erstfeld, Goldau and Luzern. The telegraphs with their Morse keys and the telegraph-relays were produced by Gustav Hasler [de] (Bern).

The Gotthard railway signal bells

The Gotthardbahn employed signal bells within its stations and along the line to signal any approaching train. An alarm was triggered once a train had left a neighbouring station or block station. These signal bells were partly installed along the line and signalled any construction worker of an approaching train. In addition, any railway watchman's house and railroad crossing would be equipped with a signal bell. Southbound trains were signalled by 3 triple chimes, northbound trains by two double chimes. The signalling mechanism at each signal bell had to be manually wound up every day by station employees and railway watchmen. Part of the mechanism was a weight having to be raised by help of a pulley. The electric signal triggering the alarm operated a relay, activating the bell's hammer through force of the aforementioned weight. Each signal bell within the Gotthard railway's network is marked on the graphic timetable. The railway watchman's house number 159 (Casello 159) signal bell on the Monte Ceneri line between Giubiasco and Rivera-Bironico is shown as an example in the timetable's excerpt. A southbound train departing Giubiasco for Rivera-Bironico would trigger alarms of eleven different signal bells on its 11 kilometres long journey. Around 1980 these signal bells were decommissioned.

Track maintenance and safety

In the Gotthard Railway's early days ultrasound was not available to examine the tracks. Fractures within these were far more common than today, when special ultrasound equipped trains are employed in the maintenance process. The railway watchman was especially important in ensuring the Gotthard railway's safe operation. A railway watchman was assigned to a special segment of tracks which he had to inspect every day. Fractures, deformations and the tracks' general condition were to be reported to the track master. Tending to loose screws and cutting down shrubs were also part of the watchman's job description. Also putting out small shrub fires, caused by the heavily employed brakes of downhill running cargo trains, were part of his duty. The railway watchman was equipped with a red flag to be able to stop trains in an emergency. The Gotthard railway's watchmen lived in specially provided watchman houses along the line. In Italian these watchman's houses are called Casello.^[9] Every day they had to inspect the tracks up to the next watchman's segment. The watchman houses were built along the entire Gotthard line with distances of up to 4 kilometres between them and were all numbered. From 1950 onward the track inspections did not require as many inspections as before. Between Giubiasco and Rivera the railway watchmen then only had to perform such an inspection every other day. Their former watchman houses now remained unmanned and were subsequently used as holiday homes or private dwellings. From 1995 onward the Swiss Federal Railways (SBB) turned to selling these watchman houses.

Swiss Federal Railways

The Gotthard Railway Company worked the Gotthard railway until 1909, when it became part of the Swiss Federal Railways. This was seven years after the creation of that state owned railway, and the Gotthard railway was the last major railway to be absorbed. In 1922, the whole line was electrified by Brown, Boveri & Cie with 15 kV  16.7 Hz AC supplied by overhead line.^[4]

The approaches to the Gotthard Tunnel are susceptible to rockfalls, regularly leading to closures of the railway line. In the worst such incident in recent times, the Gotthard line was closed to all traffic for almost one month following a rockfall near Gurtnellen on 5 June 2012, which killed one rail worker and injured two others. The closure caused massive disruption of both passenger and international freight traffic.^[10][11]
