The Bavarian Zugspitze Railway is one of four rack railways still working in Germany, along with the Wendelstein Railway, the Drachenfels Railway and the Stuttgart Rack Railway. The metre gauge line runs from Garmisch in the centre of Garmisch-Partenkirchen to the Zugspitzplatt, approximately 300 metres below Zugspitze, the highest mountain in Germany. The line culminates at 2,650 metres above sea level, which makes it the highest railway in Germany and the third highest in Europe. It is also the railway in Europe with the biggest height difference: 1,945 metres, the lower half being open-air and the upper half being underground.
