The Austrian government placed a similar condition on its support to Austrian Airlines, demanding that the company end its 50-minute flight between Vienna and Salzburg, a journey that passengers can make by train in about three hours. The European Commission also designated 2021 as the “Year of European Rail,” seizing the opportunity to spread the word about train travel, particularly to a younger audience. While passenger traffic was growing steadily through 2019, it was starting from a low base: Before the pandemic, only 8 percent of all passenger travel in the European Union was by train. But in addition to the public relations campaign, European leaders are also working to reduce practical barriers to cross-border train travel by introducing new data-sharing systems, replacing outdated infrastructure, and building new high-speed routes, particularly in Central and Eastern Europe.
“The idea is that for train trips of less than four hours, no businesspeople will choose to fly, and for trips below six hours, normal people — tourists — will take the train,” said Alberto Mazzola, the executive director of the Community of European Railways and Infrastructure Companies, which is based in Brussels. Mr. Mazzola added that government leaders are throwing their weight behind railway infrastructure, particularly high-speed lines. “We heard this 20 years ago,” he added. “The difference today is that we are seeing the investments.”
