Wittenberge–Buchholz Railway
The Wittenberge–Buchholz railway or Wittenberge–Buchholz branch (german: Bahnstrecke Wittenberge-Buchholz or ''Wittenberge-Buchholzer Zweigbahn'') was licensed to, planned and built by the Berlin-Hamburg Railway Company (BHE) and opened in 1874 as an additional link between the cities of Berlin, Hamburg and Bremen in Germany. It ran through Wittenberge, Dömitz, Dannenberg, Lüneburg and Buchholz and was originally to have been extended to Bremerhaven. The single-tracked main line ran through the present-day states of Brandenburg, Mecklenburg-Vorpommern and Lower Saxony. With the destruction of the bridge over the Elbe at Dömitz at the end of the Second World War and the subsequent division of Germany it suddenly lost its importance and, as a result, was partially closed. Today two sections of the line are still open: the longer one of the two between Dannenberg and Lüneburg in the Wendland is known today as the Wendland Railway (''Wendlandbahn''); whilst western end of t ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...
