The two companies aim to profit from President Barack Obama's plan to expand U.S. rail infrastructure, which is part of the country's economic programme, the spokesmen said.

German magazine Der Spiegel also reported on Saturday that Siemens would supply high-speed ICE-3 trains and transport technology, while Deutsche Bahn would operate the rail links. The magazine said the U.S. government plans 11 projects to build out its rail system, including high-speed rail links between major centres such as Miami and Orlando or San Francisco and Los Angeles.
