The cost of a high-speed train set can vary wildly, depending on the requirements and configuration. A 2011 report by consultants for the U.S. Office of the Inspector General reported that the price of high-speed trains on European lines ranged from $30 million to $70 million each. A 2012 report to the British parliament on England's HS2 project estimated the cost of a high-speed train set at the equivalent of about $42 million.
