The police action caused long tailbacks. Meanwhile, the train station under the airport itself is still closed, but there is an alternative. "Travellers can take a train to Zaventem-dorp (Zaventem village). We offer 2 services from Leuven to there each hour, and 3 from Brussels."
"From there, you can take a free bus - operated by De Lijn - to the airport", says Dimitri Temmerman of Belgian Rail. Contrary to trains, bus services to the airport have already resumed. Passengers are, meanwhile, still requested to come 3 hours in advance.
