 Two of the 3-car sets, 22010 and 22011, were delivered in July 2007 with corrosion damage received in transit from South Korea.IÉ did not accept delivery and stored the sets until October 2008 when they were returned to Rotem for repair, with a revised delivery date of early 2009.It was later determined that it was uneconomic to repair them, so Rotem added two additional units to the last order at no additional cost to IÉ.
