Hi Htwong
From 16 October to 9 November, work is being carried out on the railway line between Visp and Täsch. For this reason, replacement buses are being organised. It is not possible to buy tickets for the buses, so we advise you to buy them from the driver.
The Visp - Zermatt line is not operated by SBB. For any other questions, please contact the company Matterhorn Gotthard Railway directly.
I wish you a nice day.
Kind regards
NicolasK
