Wengernalp Bahn (WAB), with 800 mm gauge track, is the world's longest continuous rack railway, connecting Lauterbrunnen, Kleine Scheidegg and Grindelwald, but the trains do not travel directly from Lauterbrunnen over to Grindelwald. Kleine Scheidegg is the starting point of the Jungfrau Railway.
Jungfrau Bahn (JB) connects at Kleine Scheidegg station
with the Wengernalp Railway. The first track section from Kleine
Scheidegg to Eiger Glacier was opened in 1898. In 1903 the
section to the Eigerwand Station, and in 1905 the section to the
Eismeer Station was completed. Finally in 1912 the railway
reached the end destination at 3454 meters (11333 ft), just
below the summit of the Jungfraujoch (4158m / 13642 ft). The
majority of this line is in a tunnel and the Jungfrau station is
the summit is a hotel, two restaurants, the Sphinx observatory
research station, and the glistening "Ice Palace" carved into
the living glacier. Called the "Top of Europe" the Jungfrau is
the highlight of any trip to Switzerland.
The Schynige Platte Bahn (SPB) was opened in 1893 and electrified in 1914. Many of its carriages and locomotives were first in service on the Wengernalp Railway. The 800 mm gauge cog railway starts in Wilderswill, near Interlaken, and climbs 1420 meters over a distance of 7.25 km. Fog and rain obscured views of the Lakes Thun and Brienz, and the peaks of Eiger, Monch, and Jungfrau. The alpine garden ls a highlight at the summit station.
