Biasca is a railway station in the Swiss canton of Ticino and municipality of Biasca. The station is on the Swiss Federal Railways Gotthard railway, at the foot of the southern ramp up to the Gotthard Tunnel.
The station is served by an hourly InterRegio train between Arth-Goldau and Locarno, most of which start from either Basel SBB or Zürich HB. It is also served by trains on line S10 of the Treni Regionali Ticino Lombardia (TILO), which operates hourly south of Biasca to Bellinzona, Lugano and Chiasso, with a few trains extending northwards to Airolo and southwards to Milan.
The line through the Gotthard Base Tunnel diverges from the existing line to the south of Biasca station (but before Osogna), passing on the surface to the west of the town before entering the tunnel proper at Bodio.
Between 1906 and 1973, Biasca was the junction for the metre gauge Biasca–Acquarossa railway to Acquarossa in the Valle di Blenio. Today it is served by buses of the Autopostale, who operate an hourly service from Bellinzona to Airolo that parallels the Gotthard railway, and Autolinee Bleniesi, who provide service to the Valle di Blenio.
