The state’s Transportation Secretary said the withdrawal of a private developer from a plan to redevelop the U.S. Postal Service facility near South Station and add additional commuter rail lines is not necessarily bad news.

The development team the Postal Service retained in 2008 pulled out last month because of financial concerns.

That halted a deal in which the Postal Service would move to a new facility a mile away, while the developers sold land behind South Station to the MBTA for new tracks and platforms to accommodate additional rail service.

Transportation Secretary Jeffrey Mullan told The Boston Globe that the departure of the private developer means the state can now deal directly with the Postal Service.

Postal Service spokespeople had no comment.
