The New Railway Link through the Alps (NRLA) (, , ), is a Swiss construction project for faster north-south rail links across the Swiss Alps. It includes base tunnels several hundred metres below the existing apex tunnels along two axes, the Gotthard and the Lötschberg. The Gotthard Base Tunnel and the Lötschberg Base Tunnel are the respective centers of those two axes. Swiss Federal Railways subsidiary AlpTransit Gotthard AG and BLS AG subsidiary BLS Alp Transit AG (now BLS Netz AG) were founded for this project and built the tunnels.
