Opened in 1891, the Seilbahn Lauterbrunnen–Grütschalp was a 1.4 km[note 1] long funicular railway between Lauterbrunnen and Grütschalp in the Bernese Oberland, Switzerland. From Grütschalp, the Lauterbrunnen–Mürren mountain railway continues to Mürren.[4][2][3] The line had a difference of elevation of 674m at an incline of 41-60%.[note 2][4] The longest viaduct on the line was 220m.[3] The funicular closed on 23 April 2006, and was replaced by an aerial cablecar in December 2006.
Water-counterbalanced line (1891 - 1902)
[edit]From line's opening in 1891 until 1902, the line was water powered. The downward car on each trip would be filled with 7m³ of water, sourced from the Staubbach, which counterbalanced the weight of the upward car. During this period, the track had three rails except at the upper station where there were four.[5]
The rope, manufactured by Felten & Guillaume, had a diameter of 32.6mm and consisted of 125 wires of 26.3mm diameter externally and 72 wires of 1.3mm diameter internally. It had a breaking strength of 62,000 kg and a weight of 3.5 kg/m.[4][1][3] By 1892 it had run approximately 5000 km and stretched by 15m in length.[1]
Electrified line (1902 - 2006)
[edit]In 1902, Swiss Locomotive and Machine Works and Joh. Jakob Rieter electrified the line and replaced the cars and cable. A power plant was built at Staubbach, 1.35 km from the upper station. The new cars had 6 compartments for 62 passengers including 54 seats, floor set to be horizontal at 52% incline, 2 axles and total weight of 7950 kg.[5]
In 1949, the Riggenbach rack was removed and the track changed from 3 to 2 rails.[7]
The rope, also manufactured by Felten & Guillaume, had a diameter of 33.6mm and consisted of 6 stands of 16 wires each (7 wires 1.85mm in diameter, and 9 of 2.65mm diameter) around a fiber core. It had a breaking strength of 63,000 kg and a weight of 3.75 kg/m.[5]
