"Are we more efficient in the market or not? This is the only real measure of success for ERTMS," Bamberger told delegates.\r\n"At present there is no positive business case for train operators," Bamberger complained. "It costs between \u20ac300,000 and \u20ac1m to retrofit a locomotive - this is unacceptable. We have an expensive and time-consuming authorisation process, which makes me speechless.\r\n"Nobody has a master plan or a commitment to roll out ETCS. There are no standard on-board units, and most networks require additional national solutions. There is no centralised steering for migration so far.\r\n"We need a serious funding scheme for operators to retrofit locomotives," Bamberger continued. "We strongly support compatibility between on-board and trackside systems and we want Baseline 3 to be frozen for 10 years."
