New York Central Railroad's Empire State Express takes on water from the track pan at Palatine, New York, in 1905. A water trough (British terminology), or track pan (American terminology), is a device to enable a steam locomotive to replenish its water supply while in motion. It consists of a long trough filled with water, lying between the rails.
Initially, these troughs played a crucial role in the city's infrastructure. [1] They provided water access to low-income workers and the general populace. [1] However, with technological advancements such as electrical pumps and the shift to motorized vehicles, there was a reduced reliance on animal-drawn carts. Consequently, the water troughs ...
The Archimedes screw generator consists of a rotor in the shape of an Archimedean screw which rotates in a semicircular trough. Water flows into the screw and its weight presses down onto the blades of the turbine, which in turn forces the turbine to turn. Water flows freely off the end of the screw into the river.
An abreuvoir is a watering trough, fountain, or other installed basin: originally intended to provide humans and/or animals at a rural or urban watering place with fresh drinking water. They were often located at springs. In pre–automobile era cities, they were built as equestrian water troughs for horses providing transportation.

Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
Left: Water stop. Right: Wall of the Stationmaster's office. A water stop or water station on a railroad is a place where steam trains stop to replenish water. The stopping of the train itself is also referred to as a "water stop". The term originates from the times of steam engines when large amounts of water were
The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...
