The AlpTransit (NRLA) project is the centerpiece of the Central European rail network.

AlpTransit, also known as New Railway Link through the Alps, NRLA (German: Neue Eisenbahn-Alpentransversale, NEAT, French: nouvelle ligne ferroviaire à travers les Alpes, NLFA, Italian: Nuova ferrovia transalpina, NFTA), is Switzerland's largest-ever construction project for faster north-south rail links across the Swiss Alps by constructing a series of base tunnels several hundred metres below the current tunnels. For safety, all the tunnels have two parallel single-track bores joined about every 300 metres with cross cuts, enabling the other tunnel to be used for escape. The $13 billion[1] project consists of two major sections, the Gotthard axis and the Lötschberg axis, including the 57-kilometre (35 mi) long Gotthard Base Tunnel and the Lötschberg Base Tunnel, respectively. The centrepiece, the Gotthard Base Tunnel, is scheduled to become operational at the end of 2016, and the Ceneri Base Tunnel four years later in 2020.[2]

Gotthard axis

The Gotthard axis, consisting of the new Gotthard Base Tunnel, Zimmerberg Base Tunnel, Ceneri Base Tunnel, and surface connections, is being built under contract from the Swiss Federal Government by the company AlpTransit Gotthard AG. The new axis will be the first flat transalpine rail link with a maximum elevation of just 550 metres (1,800 ft) above sea level. This results in a high-speed link through the Alps with a top speed of 250 km/h (160 mph) reducing travel time between Zurich and Milan from the current 4h00 to 2h30.[3][4][5]

At 57-kilometre (35 mi) long, the Gotthard Base Tunnel is the world's longest railway tunnel, as was the original Gotthard tunnel of 15 kilometres (9.3 mi) at the time of its completion in 1881. The new one consists of two 57-km long tunnels, each with one train track. The two tunnels are connected by 178 cross connections. It has two emergency stop platforms in each tunnel, they are connected with the emergency stop platform of the opposite tunnel. These stations are equipped with water refilling equipment to refill the firefighter and rescue train. One of these stations was proposed as railway station, called Porta Alpina, but got rejected. The completed tunnel was handed over by AlpTransit Gotthard AG to the Swiss government on 31 May 2016, and was formally opened in a ceremony the following day, during which the tunnel was conveyed to its intended operator, the Swiss Federal Railways (SBB CFF FFS).[6]

The Lötschberg axis, with the Lötschberg Base Tunnel in the Bernese Alps was constructed by the company BLS AlpTransit Lötschberg AG. The 34.6-kilometre (21.5 mi) long base tunnel opened to traffic in June 2007; it was the first part of the NRLA to be completed. It supports the western transit link via Basel - Olten - Bern - Brig - Domodossola - Milan. For most traffic, it replaces the existing higher altitude 14.6 km (9.1 mi) Lötschberg Tunnel that opened in 1913. Because of cost constraints, only one of the bores of the Lötschberg Base Tunnel has been completed and equipped for rail use, the other was completed one third of its length and excavated a further third with the final third unstarted. High-speed track switches allow the use of the completed third as a passing track. The second part of the Lötschberg axis is the Simplon Tunnel, completed in 1905 as a 20-kilometre (12 mi) long single-track base tunnel and augmented with a second bore in 1921. It connects the Upper Valais with the Piedmont region in Northern Italy.

Political background

In negotiations with the European Union, Switzerland demanded a limitation of transalpine heavy goods traffic which was denied by the EU. Therefore, the Swiss negotiators took another route and demanded a kilometre-based tax on heavy goods vehicles, the Distance-related heavy vehicle fee (HVF), which was to be installed for all domestic and international truck traffic above 3.5 tonnes. Negotiations subsequently turned towards the amount of that tax, and Switzerland offered to build a new high-speed rail link through the Alps for the main purpose of intermodal transport, an offer which was later accepted by the EU but not without attaching the condition that the then valid 28-tonne limit for trucks must be raised to 48 tonnes. A settlement was achieved with the acceptance by both sides of a step-by-step raise of the weight limit to 40 tonnes. Thus, the bilateral Land Transport Agreement with the European Union was reached and once the NRLA is finished, the kilometre-based tax on HGVs can be increased from 1.6 ct/tkm to 1.8 ct/tkm. This condition has been fulfilled with the completion of the Lötschberg Base Tunnel.

Further Swiss legislation demands a stop of road building in the Alps and a shift in transportation policy (Article on the Protection of the Alps, adopted 1994), the transfer of as many goods as possible from transalpine transport by road to transport by train and the setting of a Transfer Goal, a maximum number of trucks to cross the Alps by road (Traffic Transfer Act, adopted 1998). These goals however can only be accomplished with a fully functional Alptransit rail link.

Original plans for the NRLA included the construction of only one of the main base tunnels. Since no decision could be made and regional dispute threatened to put the entire project in danger, the Swiss Federal Council decided in 1996 to build both base tunnels, Gotthard and Lötschberg, simultaneously.

The total cost of the AlpTransit projects is (as of 2005) estimated at CHF 16 billion. The Swiss population accepted the project by vote on September 27, 1992 and re-approved it, accepting its new financing structure by a new public transport fund, in 1998. This fund (German: FinöV) is fed mainly by a kilometre-based tax on heavy goods vehicles, as well as part of the taxes on gasoline originally intended for road building and a minor part of VAT funds. The fund amounts to 30.5 billion Swiss francs (as of ) allocated over 20 years and funds projects other than NRLA, such as Rail 2000.
