Washington, Baltimore And Annapolis Electric Railway
The Washington, Baltimore and Annapolis Electric Railway (WB&A) was an American railroad of central Maryland and Washington, D.C., built in the 19th and 20th century. The WB&A absorbed two older railroads, the Annapolis and Elk Ridge Railroad and the Baltimore & Annapolis Short Line, and added its own electric streetcar line between Baltimore and Washington. It was built by a group of Cleveland, Ohio, electric railway entrepreneurs to serve as a high-speed, showpiece line using the most advanced technology of the time. It served Washington, Baltimore, and Annapolis, Maryland, for 27 years before the "Great Depression" and the rise of the automobile forced an end to passenger service during the economic pressures of the 1930s "Depression" southwest to Washington from Baltimore & west from Annapolis in 1935. Only the Baltimore & Annapolis portion between the state's largest city and its state capital continued to operate electric rail cars for another two decades, replaced by a b ...

Washington, Baltimore And Annapolis Trail
The Washington, Baltimore and Annapolis Trail (WB&A) is a long discontinuous rail trail from Lanham to Odenton in Maryland. Despite its name, it does not actually connect with Washington, D.C., Annapolis or Baltimore; its name is taken from the Washington, Baltimore and Annapolis Electric Railway, from which the right-of-way comes. The trail exists in two separate pieces, one in Anne Arundel County and the other in Prince George's County, separated by the lack of a bridge over the Patuxent River. The bridge's construction and the trail's alignment was delayed for over a decade due to a property dispute; however, the trail was realigned and plans exist to complete a bridge by 2021. Additional plans exist to extend the trail southward to the Washington, D.C. border. The WB&A Trail makes up part of both the East Coast Greenway - from Calais, Maine to Key West, Florida - and the American Discovery Trail - from the Atlantic coast of Delaware to San Francisco, California.

Reverse Curve
In civil engineering, a reverse curve (or "S" curve) is a section of the horizontal alignment of a highway or railroad route in which a curve to the left or right is followed immediately by a curve in the opposite direction. On highways in the United States reverse curves are often announced by the posting of a W1-4L sign (left-right reverse curve) or a W1-4R sign (right-left reverse curve), as called for in the Manual on Uniform Traffic Control Devices. Reverse curves on the Northeast Corridor in the USA hinder the development of high-speed rail. Reverse curves cause buffer-locking. See also *S bridge * Road curve *Track geometry Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of t ... References Railway track layouts {{engineering-stub ...
