A pair of law firms have teamed up to help the National Railroad Passenger Corp., better known as Amtrak, retake control of D.C.’s Union Station in the hopes of updating the 115-year-old building. 

Considered one of the busiest stations in the nation, the complaint claims a collection of subletting development groups let the facility wither thanks to “poor maintenance and lack of capital investment.”  The lawsuit was filed late Thursday by Lindsay Harrison from Jenner & Block and Patricia McHugh Lambert from Pessin Katz Law.
