Two sections of additional mainline trackage will be added to the CSX line running south through Virginia. A fourth track will be built from
Long Bridge, which crosses the Potomac, south to
Alexandria, and an third track will be built between the
Franconia–Springfield station and
Occoquan River crossing. CSX will transfer an abandoned right-of-way between
Petersburg and the North Carolina border, a critical link in the planned
Southeast High Speed Rail Corridor, to the state of Virginia. Early design and engineering work of a replaced or rebuilt Long Bridge to increase rail capacity out of Washington will also take place, through actual construction remains unfunded. Most rail construction is to take until 2020, though some minor improvements to the corridor will be completed sooner. ==References==
