Question: What is the name of the intermediate cable car station that is used to climb the Titlis mountain in the Uri Alps?
Context: The Fichtelberg Cable Car (German: "Fichtelberg Schwebebahn" ) is a German cable car in the Ore Mountains in Saxony that runs from the town of Oberwiesenthal to the Fichtelberg mountain top.  It is the oldest cable car in Germany, leading from the valley station at an altitude of 905 metres above sea level to the top station at 1,208 metres above sea level, having a length of 1,175 metres and a maximum upward gradient of 50 per cent.  The Fichtelberg Cable Car is equipped with two carrying and two hauling cables. Trübsee (1788 m ) is an intermediate cable car station by the Titlis Bergbahnen, Trüebsee (lit.: "dull lake", Germanized: "Trübsee") is an Alpine lake (1764 m ) on the Ober Trüebsee Alpine pasture (or often just incorrectly shortened to "Trüebsee") in the upper part of the extensive municipality of Wolfenschiessen in the Swiss canton of Nidwalden.  The lake lies at the foot of the Titlis above the village resort of Engelberg.  It can be reached from the village by cable car, or via several alpine walking paths, e.g. the "Pfaffenwand". The Uri Alps (German: "Urner Alps" ) are a mountain range in Central Switzerland and part of the Western Alps.  They extend into the cantons of Obwalden, Valais, Bern, Uri and Nidwalden and are bordered by the Bernese Alps (Grimsel Pass) and the Emmental Alps to the west (the four lakes: Lungerersee, Sarnersee, Wichelsee, and Alpnachersee), the Schwyzer Alps to the north (Lake Lucerne), the Lepontine Alps to the south (the valley of Urseren with Andermatt) and the Glarus Alps to the east (Reuss). The Schwyz Alps (German: "Schwyzer Alpen" ) are a mountain range in Switzerland.  They form part of the North-Eastern Swiss Alps and are bordered by the Glarus Alps to the east, the Appenzell Alps to the north-east, the Emmental Alps in the west, and the Uri Alps to the south-west.  The Klausen Pass is the highest point between the Schwyz Alps and the Glarus Alps. The mountain is about 860 metres high.  The summit can be reached in about 50 minutes by foot or in about 10 minutes by cable car from Oberaudorf.  From the top there is a view of Kranzhorn and Spitzstein.  The cable car station is accessible by car, approximately a five-minute drive from the motorway exit for Oberaudorf.  The mountain hosts a resort that has been renovated in the last 10 years with a new 4-chair lift, an illuminated night ski-slope, and a modern snowmaking system.  The resort also has the world's only summer toboggan run with a 360-degree loop. Titlis is a mountain of the Uri Alps, located on the border between the cantons of Obwalden and Berne.  At 3238 m above sea level, it is the highest summit of the range north of the Susten Pass, between the Bernese Oberland and Central Switzerland.  It is mainly accessed from Engelberg (Obwalden) on the north side and is famous as the site of the world's first rotating cable car.  The cable car system connects Engelberg (996 m ) to the summit of "Klein Titlis" (3028 m ) through the three stages of "Gerschnialp" (1262 m ), "Trübsee" (1796 m ) and "Stand" (2428 m ). Crap Sogn Gion (meaning "Saint John's stone" in Romansh) is a mountain (2,252 m) and cable car station (2,216 m) located near Flims in the Swiss canton of Graubünden.  Regarding the definition used in the Alps by the Swiss Alpine Club it cannot be called a mountain (nor even a peak with a strict definition) but only a location at the end of a ridge descending from the Vorab in the Glarus Alps. The Joch Pass (German: "Jochpass") is a mountain pass of the Uri Alps, located between the Bernese Oberland and Central Switzerland, at the foot of the Titlis.  The pass crosses the col between the peaks of Graustock and Jochstock, at an elevation of 2207 m and at the border between the cantons of Bern and Nidwalden. The Eibsee Cable Car, which opened in 1963, is a cable car which connects the lower station (973 m above sea level) near lake Eibsee with the top station at 2950 m above sea level next to the summit of Zugspitze, Germany's highest mountain on the border to Austria.  The cable car was built to provide a faster access to the Zugspitze from its German side, as the cog railway from Garmisch-Partenkirchen does not go directly to the summit and takes much longer.  The "Eibsee Cable Car" belongs to "Bayerische Zugspitzbahn Bergbahn AG", the company operating the cog railway and most cable cars, gondola lifts and chairlifts in the Garmisch-Partenkirchen area.  It is thus possible to make round trips using both the cog railway and the cable car.  On the Austrian side, there is the Tyrolean Zugspitze Cable Car which starts at Ehrwald and meets the Eibsee Cable Car on the top. The mountain is a popular destination for hiking and in Winter, skiing is also possible.  A cable car (the Laberbergbahn) brings visitors up to just below the summit of the Laber, from where a variety of footpaths lead.  There is also a restaurant at the top cable car station.
