Map of the 'Gotthardbahn'
'Gotthardbahn' was the name of a private
Swiss railway company which operated the railway line from
Immensee (
canton of Schwyz) to
Chiasso (Italian border). Nowadays this term usually does not refer to that company, but to the railway line itself.
Construction
After the
Semmering Railway, the
Brenner Railway and the
Mont-Cenis-Route the Gotthardbahn was the fourth railway line through the
Alps. Construction started 1872 after long discussions about the best layout of the line and treaties with the
Kingdom of Italy (1869) and the
German Empire (1871). The first lowland sections
Biasca-
Giubiasco-
Locarno and
Lugano-
Chiasso were opened by 1874.
The whole line was inaugurated with festivities in
Lucerne and Chiasso from
21 May to
25 May 1882. Scheduled operation started on
1 June. At the time, the 15,003-meter-long
Gotthard Rail Tunnel was the world's longest rail tunnel (seconded by the
Simplon Tunnel in 1906). Soon after construction, the line was secured by the army 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
Rotkreuz-Immensse, which provided a rail link from
Aarau to
Arth-Goldau. The feeder lines to
Lucerne and
Zurich were completed in 1887.
In 1909, the Gotthardbahn was integrated into the network of the
Swiss Federal Railways founded in 1902. The whole line was electrified with 15 kV
alternating current (singe phase, 16 2/3 Hz) in 1922.
Route
Immensee - Erstfeld
Starting at Immensee, the line follows the
Lake of Zug to Arth-Goldau (510 meters). Here the line from Lucerne joins and the
Südostbahn route to
Biberbrugg-
Rapperswil/
Einsiedeln branches; further, there is a connection to the
Arth-Rigi-Bahn, a rack railway climbing the
Rigi. Then it follows the
Lauerzer See and passes
Schwyz, the capital of the
canton of Schwyz (455 meters). From
Brunnen to
Fluelen, the line follows the
Vierwaldstätter See (that part of it is also referred to as
Urnersee). In that section, the
Axen, the two tracks are built separate due to space constraints.
Erstfeld (472 meters) is finally reached via
Altdorf, and the northern ramp begins.

The Erstfeld depot 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.
The track now gets steeper with a
gradient of up to 28‰. After
Amsteg the line passes the Chärstelenbach bridge and changes the side of the
Reuss valley over the Intschireuss bridge, which is, with its 77 meters, the highest bridge in the SBB network. After
Gurtnellen (738 meters), the first
spirals follow; their purpose is mainly to gain height where no space is available. Two of them form the double loop of
Wassen (928 meters), which allows the famous church of Wassen to be seen three times from different perspectives, first from below and the last time 200 meters above. The line passes over the river Reuss three times in this section.
After yet another 1570-meter-long tunnel
Göschenen (1106 meters) is reached, where passengers can take the train of the narrow gauge rack railway
Matterhorn-Gotthard-Bahn (former
Schöllenenbahn,
Furka-Oberalp-Bahn) to
Andermatt and from there over the
Oberalppass to
Chur or through the
Furka Tunnel to
Brig.
Gotthard Tunnel
The
Gotthard Rail Tunnel is a 15,003-meter-long, double-track tunnel, built as one tube. The highest point of the Gotthard line is within this tunnel, 1151 meters above sea level. The tunnel crosses the border between the
canton of Uri and the
canton Ticino.

Southern ramp, Airolo - Biasca
After Airolo (1142 meters), the line crosses the river
Ticino and descends through the valley
Leventina. At
Piotta, there is an 87.8% steep
funicular railway to the
Ritom dam. Behind
Rodi-Fiesso (942 meters), 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 meters' height before reaching
Faido. Two more spirals, known as the "Biaschina-Loops", lead the line down to Giornico (391 meters). The valley broadens and the line arrives at
Biasca (293 meters).
Biasca - Bellinzona - Luino
From Biasca to
Bellinzona (241 meters), the capital of the canton Ticino, the line follows the river Ticino. At
Giubiasco, the line to
Locarno and
Luino branches. Originally the main line was the track to
Luino, to connect the line with the Italian network and the
Genoa port.
Eventually, a second line over
Monte Ceneri to
Lugano,
Como and
Milan was also build for smaller and passenger only trains. For this reason the gradient on the Ceneri line is higher then the gradient of the Alp tracks.
Bellinzona - Chiasso
At
Giubiasco, the line rises again to the
Monte Ceneri and then passes through two parallel, single-track tunnels. It reaches the highest point on this part of the line,
Rivera-Bironico, at 472 meters. Then it descends to
Lugano at 335 meters.
Following the western waterside of the
Lago di Lugano, the line arrives at
Melide, where the
Swissminiatur can be found, which shows Switzerland's best known tourist features at a 1:25 scale. The Lago di Lugano is crossed over an 817-meter-long bridge and dam and the track follows the eastern waterside to
Capolago and
Mendrisio. After over 200 kilometers the station
Chiasso is reached, which houses the Italian customs and has a big international shunting yard. Conventional trains change locomotives here due to different traction voltages and
train protection systems in Italy.

Most of the Swiss locomotives were originally constructed for the Gotthard line, so many of them were called "Gotthardlokomotiven", for instance
C 5/6 "Elephant",
Ce 6/8 and Be 6/8 "Krokodil",
Ae 8/14 "Landilok",
Ae 6/6,
Re 620. Famous trainsets on the Gotthard route are the
Trans-Europe Express and the
Rote Pfeil, as well as the tilting train
Cisalpino Pendolino.
Nowadays passenger trains are mostly pulled by
Re 4/4 II (up to two for long trains) and sometimes by
Re 460, freight trains by Re 6/6 and
Re 4/4 III. Up to 1300 tonns may be pulled by an Re 6/6 with an Re 4/4
III (this combination is sometimes referred to as Re 10/10); if the trains are heavier they have to be pushed by an additional Re 4/4 or Re 6/6, because the couplers are too weak to pull the entire train on the steep slopes.
Besides trains operated by the Swiss Federal Railways, other railway companies also run their trains on the Gotthard route since 2001 ("open access"). This includes, for instance,
Cisalpino AG (Pendolino and ordinary passenger trains),
Deutsche Bahn AG (mostly freight from Germany to Italy) and the
Südostbahn (
Voralpenexpress).
