Bane NOR has selected consultancy PwC to carry out an independent investigation into the events that led to the multi-billion-euro Folloban railway being suspended shortly following its opening. PwC, on its part, will enlist the help of Holte Consulting AS and other technical subcontractors to carry out the evaluation. The investigation will be concluded in June. Problems on the Folloban arose shortly after the festive opening of the railway between Olso and the city of Ski last December. Smoke was discovered coming out of a technical facility at Ski station. The problem was assumed as being an electrical grounding issue, which then caused electrical overheating. This then prompted a major overhaul of the system. Bane NOR teams soon discovered that the inspection and repairs of the cable terminations and joints was more time-consuming than anticipated.
