A design fault has been identified as the cause of cracks found in the frame of one of Ukrainian Railways HRCS2 trains.
On February 12, Ukrainian Railways withdrew 10 trains built by South Korean manufacturer Hyundai Rotem after discovering the fault.
Initial tests have suggested that the cracks were caused by a design defect. Further trials are being conducted this week and if the results support the earlier findings, Hyundai Rotem has agreed to repair the trains under the existing warranty, but it could be up to six months before the vehicles return to service.
The nine-car HRCS2 train sets were ordered by Ukrainian Railways prior to Euro 2012 to operate between Kiev and Dnipropetrovsk, Donetsk, Kharkiv and Lviv.
