Hitachi Ltd. is aiming to expand its rail business in the U.S. by bidding for streetcar and light-rail projects as President Donald Trump pledges to spend as much as $1 trillion to upgrade infrastructure across the country.

The Japanese conglomerate "sees quite a big opportunity" in the U.S., Alistair Dormer, chief executive officer of Hitachi Rail Europe Ltd., said in a recent interview in Tokyo.

"When there's a political change, perhaps as seismic as happened at the moment, I think everyone pauses and says, what is going to happen?" Dormer said in Tokyo. "One has to look at what will be the 'Buy America' policy going forward and then we need to decide the right strategy."
