Neabsco Creek to Woodbridge Third Track (Siding D) will add approximately 3 miles of third track in Prince William County from south of Dawson Beach Road to north of Neabsco Creek, and will include the construction of new, two-track railroad bridges. The project also will include modifications to the at-grade crossing at Featherstone Road and the existing Featherstone interlocking to accommodate the third track. Siding D will increase the efficiency of passenger and freight trains throughout the rail network and will target the area south of Rippon station.

Siding D will increase network fluidity and reduce delays due to passenger and freight train congestion.
