The Gotthard railway (

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

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.

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,

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

£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

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

Arth-Goldau
were completed in 1887.

Early railway operations

The Gotthard railway timetable from 1899

Timetable of Gotthard Railway 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

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

An Electrical Telegraph of Gotthard Railway

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]

North of Arth-Goldau

The

Rotkreuz to the north.[14]

Immensee station is considered the starting point of the main line of the Gotthard railway, and official distances to all points south are measured from here. From Immensee, the line follows the

Arth-Rigi-Bahn, a rack railway climbing the mountain Rigi.[14]

The Zug branch of the Gotthard railway commences in the city of Zug. It makes a junction, in Zug station, with the line to Zürich via Thalwil. The line then follows the east shore of the Lake of Zug to reach Arth-Goldau.[14]

Arth-Goldau–Erstfeld

From Arth-Goldau, the line then follows the

Urnersee). In that section, the Axen, the two tracks follow two different routes mainly in tunnel because the second track was built later (up to 1943) and on a straighter route through longer tunnels.[14]

At Flüelen station, the railway makes a connection with the steamer services on Lake Lucerne. Steamers operate a shorter, in distance, but longer, in time, service to the city of Lucerne, serving many other towns and villages along the lake shore. The Gotthard Panorama Express uses this interchange to provide its tourist oriented boat and rail service between Lucerne and Lugano.[5]

Erstfeld, at an altitude of 472 metres (1,549 ft), is reached via Altdorf. The depot at Erstfeld station houses rolling stock needed for the Gotthard route, i.e. for banking service. A Ce 6/8 "crocodile" serves as a memorial for the legendary Gotthard locomotives.[15]

Northern ramp, Erstfeld–Göschenen

For the whole of the northern ramp from Erstfeld to Göschenen, the line follows the valley of the

Amsteg the line passes the Chärstelenbach Bridge and changes the side of the valley over the Intschireuss Bridge, which is, with its 77 metres (253 ft), the highest bridge in the SBB network.[15]

After Gurtnellen, at an altitude of 738 metres (2,421 ft), the first of several tunneled railway spirals is encountered; their purpose is mainly to gain height where no space is available. Two of them form the double loop of Wassen, at an altitude of 928 metres (3,045 ft), which allows the famous church of Wassen to be seen three times from different perspectives, first from below and the last time from 200 metres (660 ft) above. The line passes over the Reuss twice, and the Meienreuss three times in this section.[15]

After a 1,570-metre-long (5,150 ft) tunnel, the line reaches

Brig.[15]

Gotthard Tunnel

Main article: Gotthard Tunnel

Immediately after Göschenen station, the Gotthard railway enters the Gotthard Tunnel, a 15,003-metre-long (49,222 ft), double-track tunnel, built as one tube. The highest point of the Gotthard line is within this tunnel, 1,151 metres (3,776 ft) above sea level, which makes it the

Italian-speaking part.[15]

The line exits the tunnel at Airolo, at an altitude of 1,142 metres (3,747 ft) in the valley of the river Ticino, which it follows as far as Bellinzona.[16] Both north and south portals are within a few hundreds metres from those of the Gotthard Road Tunnel.

Southern ramp, Airolo–Bellinzona

After passing through

Leventina. Between Airolo and Biasca the line falls by no less than 849 metres (2,785 ft) in 46 kilometres (29 mi).[16]

At

Rodi-Fiesso, at an altitude of 942 metres (3,091 ft), the most impressive section of the southern ramp begins. The valley narrows to the Piotta canyon, and the line passes two spirals ("Piottino-Loops") to lose 200 metres (660 ft) in height before reaching Faido. Two more spirals, known as the "Biaschina-Loops", lead the line down to Giornico, at an altitude of 391 metres (1,283 ft).[16]

By the time the line has arrived at Biasca, at an altitude of 293 metres (961 ft), the valley has widened, and the gradient reduced. From Biasca station the line continues to follow the Ticino as far as Bellinzona, at an altitude of 241 metres (791 ft) and the capital of the canton of Ticino.[16]

Bellinzona–Luino / Locarno

Main article: Giubiasco–Locarno railway

Just beyond Bellinzona station, a major junction is reached at Giubiasco. Here the original main line branches off what is now considered the main Gotthard line to Lugano and Chiasso.[16][17]

What was originally considered the main line continues down the valley of the Ticino, crossing the Italian border and continuing to meet the Italian railway system at Pino on the eastern shore of Lake Maggiore. The line beyond Pino to the Italian town of Luino, although Italian-owned, has always been operated as part of the Swiss system.[18]

At

Domodossola–Locarno railway.[18]

Bellinzona–Chiasso

At

Monte Ceneri Tunnels. It reaches the highest point on this part of the line, at Rivera-Bironico station, at an altitude of 472 metres (1,549 ft), before descending to Lugano, at an altitude of 335 metres (1,099 ft).[17]

At

metre gauge railway to the town of Ponte Tresa. Following the western waterside of Lake Lugano, the line crosses Lake Lugano at the Melide causeway, a 817-metre-long (2,680 ft) causeway and bridge.[17]

The track follows the eastern waterside from the Melide causeway to

marshalling yard. Conventional trains change locomotives here due to different traction voltages and train protection systems in Italy.[17]

Services

The Gotthard line carries a mixture of freight and long distance passenger trains over the full length of the line. The long distance passenger trains include

ICN and IR trains between a number of cities in northern Switzerland and various points in Ticino. Passenger trains using the Gotthard line in the past included the Trans Europ Express trains Gottardo, Roland, and Ticino
.

Regional

Luzern, Arth-Goldau and Brunnen
.

To the south, the Gotthard line is served by trains on line

S30 also operate over the Gotthard railway in the Bellinzona area, before proceeding down the branches to Locarno and Luino respectively, with some S30 trains extended to Milan Malpensa Airport
.

Besides trains operated by the

Deutsche Bahn AG
, who operate through freight trains from Germany to Italy.

Rolling stock

A preserved "Crocodile" at Erstfeld - 14270 is now protected from weather and may return as a monument to Zürich Oerlikon, its birthplace
SBB Re 6-6 Nr. 10601 at Wolhusen.

Most of the Swiss locomotives were originally constructed for the Gotthard line, so many of them were called "Gotthardlokomotiven", for instance

Roter Pfeil, as well as the tilting train, Cisalpino Pendolino
.

Nowadays passenger trains are mostly pulled by

Re 4/4 III. Up to 1300 tons may be pulled by an Re 6/6 with an Re 4/4 III. This combination is sometimes called a Re 10/10. If the trains are heavier, then any additional locomotives must be used as banking locomotives
at the rear of the train, because the tractive effort of more power at the front of the train would exceed the capacity of the couplers within the train.

Civil engineering

Bridges

Chärstelenbach Bridge near Amsteg with fish-belly reinforcements[19]

The Gotthardbahn and its branchlines pass over a total of 1234 bridges and open passages which span a total of 6,471 metres (21,230 ft). Arch bridges from stone were only constructed up to a clear width of 12 metres (39 ft), bridging larger distances with iron superstructures, which therefore became a frequent sight on the original Gotthard line, their iron representing a weight of 17723 tons. The construction of each bridge represented its own individual challenge, depending on the surrounding geography and geology.[20]

Intschireuss Bridge with fish-belly reinforcement[21]

With the exception of three arch bridges all steel bridges consisted of very simple, straight, single beam truss constructions. These had to be reinforced already before 1914 still during steam operation of the Gotthardbahn due to quickly increasing traffic and load. Fish-belly truss structures were attached to the bridges from below where possible and an arch truss structure was added from the top, where a short clear height made this necessary, besides other measures. Eventually all original iron bridges had to be replaced with modern bridges because they had been built and were repeatedly reinforced to specifications that again and again were surpassed by increasing traffic, velocity and load.[20][22]

Notable originally single beam truss bridges on the Gotthardbahn are:[20]

  • The Chärstelenbach Bridge has two passage ways with clear widths of 50 metres (160 ft) each and rails at 53 metres (174 ft) above low water. The bridge was reinforced with a fish-belly structure. The modern replacement still uses the centre column and the stone arch abutments of the original.
  • The Intschireuss Bridge spans the widest clear width of 75 metres (246 ft), with rails at 76 metres (249 ft) above low water. The bridge was reinforced with a "fish-belly" before the iron structure was replaced.
  • The Middle Meienreuss Bridge spans 65 metres (213 ft) with rails 72 metres (236 ft) above the river bottom. The original iron construction has been replaced.

Current developments

The historical route, with its long climbs and spiral routings, restricts speed and capacity on this important international route. As a result, a largely new lower level route was constructed as the Gotthard axis of the NRLA project.

A train about to pass over the north portal of the Gotthard Base Tunnel

The

Sedrun, rather than the Gotthard Pass, but still below the Saint-Gotthard Massif.[1][23] This redundancy helped relieve some of the new tunnel's traffic after a train accident on 10 August 2023 severely reduced capacity.[24]

The Ceneri Base Tunnel, from Camorino to the south of Bellinzona, and Vezia to the north of Lugano, opened in 2020. This tunnel has a route length of 15.4 kilometres (9.6 mi) and allows trains to bypass the steep grades of Monte Ceneri.[1][25]

The Gotthard Base Tunnel opened in 2016, and the Ceneri Base Tunnel in 2020. Now that they have opened, all rail traffic still needs to use the existing route north of Erstfeld, between Biasca and Bellinzona, and south of Lugano. The bypassed sections of the existing route are being retained for local passenger services, for general capacity and as a diversionary route.[25][26]

Further bypasses have been planned as part of the Gotthard axis of the NRLA project, including a new largely tunnelled route from

Arth-Goldau to Erstfeld, and an extension of the existing Zimmerberg Base Tunnel on the route between Zürich and Zug. No commitment to construct these sections of line has yet been made.[25]

Operator Sudostbahn has announced, as of 13 December 2020, it will run a new service from Basel and Zurich via the original Gotthard line, using

Stadler Flirt
units which are also used on the Voralpen express.
