The new trains are built around Alstom's Coradia Stream platform already in use in Italy and will replace Denmark's diesel-powered trains.

"With the order of new electric trains we can look forward to retiring the aging diesel trains in a few years," the chairman of DSB, Peter Schütze, said in a statement.

The new trains, which will each comprise five carriages, are scheduled to enter service in late-2024 with the last deliveries due in 2030, DSB said, adding the deal included service and maintenance.

The purchase comes after a botched purchase of Italian trains more than a decade ago. Technical problems with the 85 trains, of which less than half are currently still in use, ended up costing the Danish state hundreds of millions of dollars, causing a public outcry.

The railway operator said it expects to purchase another 50 trains at a later stage.
