The new service will connect Feldkirch, Austria, with Nendeln, Liechtenstein, and Buchs in Switzerland.
The first stage of the project will cost around €187m. The funding is split between the partners involved and had been under discussion for a while but now a solution has been found. Liechtenstein will contribute €63m (33.75%) and Austria will fund the rest. Under a previous proposal in 2012, Liechtenstein would have contributed €45m to the scheme that was then estimated to cost €90m.
The core of the project involves track doubling the 4.6km section between Nendeln and Tisis, Austria, and upgrading Nendeln station so that it can be used by Vienna - Zürich Railjet services. This will support an hourly S-Bahn service with trains running every 30 minutes during peak periods plus the two-hourly Railjet service.
The entire line from Feldkirch via Liechtenstein to Buchs, which is owned and operated by ÖBB, will be doubled at a later stage.
