In 1890 the concession to build a line was given from
Stansstad to
Engelberg. The opening of the
Stansstad-Engelberg-Bahn (StEB) followed in 1898. The opening of the railway resulted in the early demise of the
Stansstad–Stans tramway, which connected Stansstad and Stans between 1893 and 1903. The line was electrified from its beginning, making it the longest electrically operated railway line of Switzerland at that time. Because of the maximum gradient of 25% on the rack section between
Grafenort, Engelberg and Engelberg, it was decided to use
three-phase alternating current. Brown Boveri delivered seven 52 kW motorcoaches, with wooden bodies and side doors to each compartment, between 1898 and 1900, numbered 1 to 7. They also delivered, between 1898 and 1913, five 4-wheeled 110 kW rack bankers which were used beyond Grafenort on the steep uphill section, to assist the motorcoaches up the hill. These were also numbered 1 to 5. All these vehicles survived until 1964. The railway ended at that time in Stansstad at the
Lake of Lucerne. Passengers had to continue by lake steamer or bus. To connect the railway with the national rail network in
Hergiswil, where the metre gauge Brünigbahn of SBB had a station, a concession was passed in 1956. However, it took some time to find the money to build the line to Hergiswil. To resolve the problems of old loans, a new company was incorporated in 1959, still named
Elektrische Bahn Stansstad-Engelberg. In 1960 work on the Lopper tunnel started and on 27 August 1964, the last three-phase train reached Engelberg. The rack line was rebuilt to Brünigbahn standards and a new overhead line for 15 kV Hz was built. On 19 December 1964, the line went back into business as the
Luzern-Stans-Engelberg-Bahn (LSE). The new motor coaches were built for the same maximum speed as the contemporary Brünigbahn motive power (). In 2005 the LSE merged with the
Swiss Federal Railway's
Brünig line to form the
Zentralbahn railway company. Formally, the Swiss Federal Railway sold the Brünig line to the LSE which paid for it with its own shares. LSE was subsequently renamed Zentralbahn and of its shares are now owned by SBB. ==Route==
