The station is due for big improvements that'll better knit together Metro, Amtrak, and MARC. (Plus the eastern terminus of the future Purple Line.) The plan also envisions significant residential and commercial development. It won't benefit me, but I can envision many travelers getting off or boarding at New Carrollton instead of Union Station in downtown DC.
