Visitors have been stuck in the mountain resort for two days after snow blocked road and rail links.
"The railway line between Zermatt - Tasch will reopen. The first train leaves at 11.15 am (1015 GMT), a statement on Zermatt's official site said.
Tasch is a small Swiss village six kilometres from from Zermatt that serves as a gateway for those travelling in the Matterhorn mountain region.
The statement added that the rail network in Tasch remains closed due to snow, but replacement buses are operating, making it possible for people to reach regional airports.
