 The first train was delivered on 22 October and was put into use on the Sørland Line from 1 November . Scheduled travel time was reduced by 40 minutes to 3 hours and 40 minutes . In December , the trains had problems with the pantographs not working correctly in cold weather , causing the trains to lose power and be several hours delayed . NSB stated that a contributing cause was the previous year 's mild winter , which made it impossible to test the trains in extreme weather . After two and a half months of operation on the Sørland Line , every other train was at least 5 minutes late and every tenth train at least 20 minutes late . The trains also caused travel sickness , also among employees , particularly on the section from Kristiansand to Bø . NSB stated that this had also occurred on the old trains and that it was reports of the number of people affected were exaggerated .
