The head of the federal Department of Transportation said on Thursday that the Trump administration would take control of the renovation of Pennsylvania Station away from the Metropolitan Transportation Authority.

The station, one of the busiest and also most maligned transit hubs in the world, has for decades been on the verge of a massive overhaul to remedy its cramped and dreary corridors. But the competing priorities of local, state and federal stakeholders have made progress difficult.

It was not immediately clear what the administration’s vision for Penn Station might look like. Nor was it known whether the administration supports one of the various proposals for renovating or expanding the station.

The federal transportation department said the move would save $120 million by putting Amtrak in charge of a master plan for renovation and possible expansion.

This is a developing story and will be updated.
