High-speed rail in the Kadersaryinan Islands

High-speed rail is uncommon in the Kadersaryinan Islands, however certain states have made moves to start the transition to high-speed rail.

Laioria
The Laiorian HSR project was originally announced in 2011 by the Minister for Transport and Prime Minister Phil Wieniawski as a "quick route from west to east and north to south" in the country, based on the Japanese system at 120 mph. While it was rumoured Wieniawski wanted a version of the  system, the Transport Ministry was quick to respond that the Laiorian HSR needed to make use of existing infrastructure. The project was to be managed by Laioria Railways, the state-owned railway company.

HSR was modelled on the Spanish system yet uses the, to ensure compatibility with other local railways. For example, rail operations in are able to use the high-speed lines in Laioria although they do not have a dedicated high-speed railway. There are currently two high-speed rail lines: HSR 1 from west to east and HSR 2 from south to north, completed in 2021 and 2023 respectively.
