Talk:History of surface transit in Northern Virginia/Route notes

The second column is green if the old route evolved into the current (or last existing) route, red if it didn't, and not colored if I can't tell.

Alexandria-Washington Buses, Inc. (Blue Line) stopped operations between Arlington and Washington on July 23, 1932; ran past the intersection of Russell Road and Walnut Street

AB&W took over Washington, Alexandria and Mount Vernon Railway on March 20, 1930

Washington-Alexandria Transit Company (Green Line) between Washington and Camp Humphreys (Fort Belvoir); used Russell Road; probably discontinued very early (bankrupt in 1921)

AB&W had routes to the southwest and south (along and south of Columbia Pike), plus Alexandria-Arlington and Seven Corners

WV&M had routes to the west (along and north of Arlington Boulevard), plus Washington Boulevard-Pentagon and Glebe Road
