Cheb–Oberkotzau Railway
The Cheb–Oberkotzau railway is a railway line in Bavaria, Germany, and the Czech Republic which was built as a main line. It begins in Cheb and runs via Františkovy Lázně, Aš and Selb to Oberkotzau. The line was originally planned as a direct railway link between Cheb and Hof; but the plan was changed so that the existing Ludwig South-North Railway between Oberkotzau and Hof was shared. The section Aš–Selb-Plößberg was closed during the Cold War, but rebuilt and reopened in 2015. History Early days The city of Hof tried as early as 1845 to be linked to the newly emerging railway network. The priority was to create a direct link to the west Bohemian coal mines so that the local industry could be better supported and supplied. Because the Kingdom of Bavaria did not at first want to build such a link itself, another solution was sought. The city of Hof took out a loan from the Royal Bank in Nuremberg of more than 10 million German gold marks and was granted the concessi ...

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 ...
