WOD meaning in Regional ?

The Washington and Old Dominion Railroad (colloquially referred to as the W&OD) was an intrastate short-line railroad located in Northern Virginia, United States. The railroad was a successor to the bankrupt Washington and Old Dominion Railway and to several earlier railroads, the first of which began operating in 1859. The railroad closed in 1968.

The Railroad's oldest line extended from Alexandria on the Potomac River northwest to Bluemont at the base of the Blue Ridge Mountains near Snickers Gap, not far from the boundary line between Virginia and West Virginia. The railroad's route largely paralleled the routes of the Potomac River and the present Virginia State Route 7 (VA Route 7).

The single-tracked line followed the winding course of Four Mile Run upstream from Alexandria through Arlington to Falls Church. At that point, the railroad was above the Fall Line and was able to follow a more direct northwesterly course in Virginia through Dunn Loring, Vienna, Sunset Hills (now in Reston), Herndon, Sterling, Ashburn and Leesburg.

The line turned sharply to the west after passing through Clarke's Gap in Catoctin Mountain west of Leesburg. Its tracks then continued westward through Paeonian Springs, Hamilton, Purcellville and Round Hill to reach its terminus at Bluemont.

A branch connected the line to Rosslyn. The Washington and Old Dominion Railroad Trail (W&OD Trail), the Bluemont Junction Trail, the Mount Jefferson Park and Greenway Trail, several other trails, Interstate 66 (I-66), and Old Dominion Drive (VA Route 309) have replaced much of the railroad's route.
