The Swedish Transport Administration said that the decision would affect railway traffic in the capital between Saturday 2pm and Sunday 4am.
Its press officer Bengt Olsson said they had “never before had to cancel this many departures because of staff shortages due to illness, despite two years of a pandemic”.
The cancellations will affect long-distance trains as well as regional trains, commuter trains and freight trains. The mainly concern trains in Stockholm, but could also affect departures from other places in Sweden on their way to or through the city.
The Transport Administration explained the reason behind the decision as not being able to operate train traffic at full capacity and wanting to avoid leaving trains standing still.
Record-high infection rates due to the ongoing Omicron outbreak in Sweden have caused staff shortages in many sectors, including hospitals and schools. This is because of people being infected themselves, or having to quarantine as a close-contact case.
