HGZ Alemannia, known fully and officially as Hochgeschwindigkeitzuglinie von Alemannien is a 7,651-kilometre (4,754 mile) high-speed rail network connecting the constituent countries of Alemannia. It consists of the HGZ Nord line, running from Anlaufhafen to Flussmund, and the HGZ Süd line, running from Anlaufhafen to Königsreh. Requiring heavy intergovernmental cooperation to achieve, the HGZ is the largest and longest high-speed rail network in the world.
The HGZ initially opened in 1992, connecting the city of Krasno in Hytekia to the Mascyllary capital, with stops along the route in Tudonia, namely Sigairen. The success of the line at first prompted heavy investment from the Kustlan, and an extension to the line was built from Königsreh to Ljouwert, running through three other major Kustlandic cities (Lekkum, Aldtsjerk and Tsjalberg) in 1998. However, the termini of the Kustlandic Line in Königsreh was later scrapped as the city of Flussmund was added to the network in 2000, prompting the first separation into northern and southern lines, and the first connection link between the two initial Mascyllary termini. Further expansion to Skylge and Doanjum in 2003 and 2005 began the development of a rail link to the Juznik capital, Visnevas, which opened in 2007. A connection line between Visnevas and Pekrasta was opened in 2010, although not without controversy. The final developments to the network included the expansion to Lielosta and Anlaufhafen in Liiduria, of which Suurladu Station would become the new western termini, and a ferry link of Skylge to Sangashámman, the Alriikan capital, both of which opened in 2015.
