(AP) – Two Democratic state lawmakers are asking Gov.-elect Scott Walker to explain how he’ll pay for certain train-related expenses after the Republican refused federal funds that would have covered them.

Walker turned down $810 million to build high-speed rail between Madison and Milwaukee. He said the state could get stuck paying for upkeep.

Mark Pocan in the Assembly and Mark Miller of the Senate told Walker on Wednesday his refusal means Wisconsin taxpayers could now be liable for related projects worth $101 million.

Those include $52 million for a train-maintenance facility and $30 million for freight-rail upgrades.

However, fiscal analyst Jon Dyck of the state Legislative Fiscal Bureau says lawmakers have the option of scaling back the projects to save money.

Walker’s office didn’t immediately return a message seeking comment.
