According to the New York Times, the federalRailroad regulators are in talks with Elon Musk's tunneling company The Boring Company (TBC) on a multibillion-dollar Amtrak project.

Federal Railroad Administration officials have spoken to TBC to see if the Musk-owned company could save the agency money on the Frederick Douglass Tunnel project, the New York Times reported, citing people familiar with the matter.
The project, designed to connect Baltimore to Washington and Virginia, was initially expected to cost $6 billion, but current estimates suggest it could cost as much as $8.5 billion.
While TBC is one of several companies being considered for new engineering contracts, the talks have raised concerns about Musk's many conflicts of interest as he divides his time between the companies he owns, his role as President Trump's right-hand man, and as a regulator for DOGE, which has cut resources from the agency that oversees his business.
