The Bayerische Zugspitze scenario is based on the railway of the same name, a 19km railway which is one of only four rack railways still working in Germany, running from Garmisch to the Zugspitze, the highest mountain in Germany. With its summit terminus at 2,650m above sea-level, it is the highest railway in Germany and the third highest railway in Europe.
The railway was built between 1928 and 1930 - the first stage, between Grainau and the Eibsee, opened on 19th February 1929. On 19th December in that year the second section, between Garmisch and Grainau opened. The third and final section between the Eibsee and the station at the summit of Schneefernerhaus was opened on 9th July 1930. From the Schneefernerhaus a cable car ascended to the summit - these days, however, the railway branches off the original tunnel and terminates on the Zugspitzplatt plateau instead.
This scenario was created as a thank you to Lookout Games for, in Tony's words, "being so awesome", and in consequence is only available in German, although English rules can be found on the BGG website here.
