The largest bus company acquired by WMATA was DC Transit System, primarily serving the District of Columbia. By the time of the WMATA takeover, all DC Transit routes numbered below 30 had been restructured. And those numbers below 30 were assigned to routes inherited from the two bus companies in Virginia. Most route numbers were the same as those used by those companies. WV&M adopted route numbers by 1930, while AB&W adopted route numbers in 1963. Both companies used suffix letters for many routes and branches, which are not listed.
WV&M acquired its routes from earlier companies in 1926 and 1927, except for the Arlington & Fairfax Motor Transportation Co., which was acquired in 1947. That company was formed in 1932 as a bus subsidiary of Arlington & Fairfax Electric Railway Co.
In 1927, AB&W and WV&M each acquired a route from the Alexandria & Suburban Motor Vehicle Co. That company was formed in 1925 as a bus subsidiary of the Washington-Virginia Railway Co.
The Alexandria Motor Bus Line was originally formed in 1921, and its routes were acquired by AB&W in 1924. AB&W also operated several routes numbered 20 through 26, mostly under contract with United States government defense agencies, where few public timetables were ever published, and little information is available.
Certain routes were eventually discontinued, or consolidated into other routes, as noted, and are in parentheses. Several routes in Virginia eventually became part of the Fairfax Connector system.
Newer routes created by WMATA are not listed.
