Elkhorn Grade Electrification
The Elkhorn Grade Electrification was a project undertaken by Westinghouse in 1913–1915 to electrify a section of the Norfolk and Western Railway's Bluefield Division in Virginia and West Virginia. Electrification would be extended further in the 1920s and the length of the electrified line would reach before the N&W abandoned it in 1950. Background In the early twentieth century the Bluefield Division of the Norfolk and Western Railway featured a forbidding two percent average grade. Multiple 2-6-6-2 Class Z1 "Mallet" steam locomotives labored hauling coal trains up and down the grade. Although most of the route was double track, it narrowed to a single track at the Elkhorn Tunnel, which was long and itself on a % grade. Steam-powered trains were limited to in the tunnel, and delays were common. History Working with Westinghouse, the Norfolk and Western electrified a segment between Bluefield, Virginia and Vivian, West Virginia. The N&W constructed a power plant at ...

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Track
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side a ...

Electric Railways In Virginia
Electricity is the set of physics, physical Phenomenon, phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing Work (physics), work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an externa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
