Khana Junction (Bengali: খানা জংশন) is a railway station in Bardhaman Sadar North subdivision of Bardhaman district in the Indian state of West Bengal.
During the middle of the nineteenth century, M/s Carr, Tagore & Company transported coal from Narayankuri ghat on the Damodar River to Kolkata, then known as Calcutta. However, as the flow of water in the river was inconsistent, supplies were irregular. In order to capture the lucrative coal transport business, East Indian Railway, extended the railway track that had been laid between Kolkata and Hooghly to Raniganj in 1855.
Construction of what was then considered to be the Howrah-Delhi main line was started in 1859, when the Khana junction-Rajmahal line was built. In 1866 Kolkata and Delhi were directly linked. With the completion of the 406 kilometres (252 mi) long line connecting Raniganj with Kiul in 1871, a "shorter main line" was in position. Initially, it was called the chord line. However, as it attracted more traffic it was designated the main line and the original line, operating between Khana Junction and Kiul Junction, became the Sahibganj Loop.

An electrical junction may be either a thermoelectricity junction, a metal–semiconductor junction or a p–n junction (p-type semiconductor–n-type semiconductor junction). Junctions are either rectifying or non-rectifying. Non-rectifying junctions are called ohmic contacts. Electronic components employing rectifying junctions include p–n diodes, Schottky diodes and bipolar junction transistors.
A road junction is a location where multiple roads intersect, allowing vehicular traffic to change from one road to another.
Roads began as a means of linking locations of interest: towns, forts and geographic features such as river fords. Where roads met outside of an existing settlement, these junctions often led to a new settlement. Scotch Corner is an example of such a location.
In the United Kingdom and other countries, the practice of giving names to junctions emerged, to help travellers find their way. Junctions took the name of a prominent nearby business or a point of interest.
As road networks increased in density and traffic flows followed suit, managing the flow of traffic across the junction became of increasing importance, to minimize delays and improve safety. The first innovation was to add traffic control devices, such as stop signs and traffic lights that regulated traffic flow. Next came lane controls that limited what each lane of traffic was allowed to do while crossing. Turns across oncoming traffic might be prohibited, or allowed only when oncoming and crossing traffic was stopped.
