The Ceneri Base Tunnel (CBT, Italian: Galleria di base del Monte Ceneri) is a Swiss railway base tunnel in the canton of Ticino. It passes under Monte Ceneri between Camorino in the Magadino Flat and Vezia near Lugano; it bypasses the former high-altitude rail route through the Monte Ceneri Tunnel. It is composed of two single-track tunnels, each 15.4 km (9.6 mi) long. It is part of the New Railway Link through the Alps (NRLA) project for faster north-south rail links across the Swiss Alps. An exploration tunnel near Sigirino was excavated between 1999 and 2003 to gain geological data on the rock formations at the Ceneri Base Tunnel's level. Based on those data, it was decided to excavate most of the tunnel with traditional blasting methods and only drill a small part using a faster tunnel boring machine (TBM). Both the CBT and Gotthard Base Tunnels were built under contract from the Swiss Federal Government by Alptransit Gotthard AG. Construction of the two single-track bores started during March 2006. The official start of the CBT's construction phase was celebrated on 2 June 2006 with the laying of a foundation stone. The final breakthroughs took place on 21 January 2016 (west tube) and 26 January 2016 (east tube). Rail service started on 4 September 2020 and was operationalised for freight in December 2020.On opening, the Ceneri Base Tunnel has become an important southern feeder for the Gotthard Base Tunnel as the existing, proportionally steep and curvy track over Monte Ceneri is not suitable for high speeds or heavy freight trains. Another feeder is the Luino link along Lake Maggiore which is about to be upgraded by Italy in prospect of the opening of the Gotthard Base Tunnel. Both links meet in the Magadino Flat in the future Camorino Node (Italian: Nodo di Camorino). The CBT will ease local train traffic, mainly between the two major cities Locarno and Lugano but also between Bellinzona and Lugano. Travel time on the TILO, an S-Bahn, from Locarno to Lugano dropped from 50 to 22 minutes.

Giubiasco railway station (Italian: Stazione di Giubiasco) is a railway station in the Swiss canton of Ticino and municipality of Bellinzona. The station is on the Swiss Federal Railways Gotthard railway, between Bellinzona and Lugano, and is a junction point with several other lines.To the south of Giubasco, the Gotthard Railway leaves the valley of the river Ticino that it has followed since it left the Gotthard Tunnel, and heads for Lake Lugano. Just to the south of Giubiasco station, the Gotthard railway's original line diverges to the south and commences its steep climb to the high-level Monte Ceneri Tunnel under the Monte Ceneri Pass. However most trains no longer take this route, but instead continue along the main line and take the Ceneri Base Tunnel (opened in December 2020) direct to Lugano. Just beyond the junction with the original line, a second triangular junction connects the new Gotthard main line with the Luino–Bellinzona railway, which in turn has a branch to Locarno.As a major junction station, Giubiasco has two island platforms serving four platform tracks, together with a number of freight tracks. However, most long-distance passenger trains pass through the station without stopping, serving instead Bellinzona station, one stop to the north.
