Rail services between Sweden and Denmark reduced as summer holidays get under way

Only one track will be open to traffic until June 9th, warned Swedish public transport operator Skånetrafiken.

Skånetrafiken asked for travellers' patience and understanding as urgent work is carried out to replace 3,500 metres of rails through the tunnel section of the combined bridge-tunnel connecting Denmark and Sweden.

"It's unfortunate that this work has to be carried out at short notice, for such a long period of time," said Kevin Brandt Leander, business lead for the Öresund trains at Skånetrafiken, in a press statement.

"We know how important train traffic across the bridge is for the region, and the bridge section in particular is sensitive as it can be difficult for our passengers to sort out other means of transport," he added.

Replacement buses will be called in during rush hour, but delays are expected. Bicycles are not allowed on the buses.

Allow for longer journey times especially if you're travelling from Malmö to Copenhagen Airport, and remember that although Skånetrafiken does on occasion refund train tickets if journeys are unexpectedly delayed, they won't refund your flight if you miss it as a result of delays.
