Abstract: A train wash (1) for washing a train is described. The train wash comprises a water supply tank, for holding water for washing the train, a heater, for heating the water in the water supply tank, one or more water jets (14), for directing water from the water supply tank onto a side of the train, one or more rotatable brushes (4), for brushing against a region of the train onto which water is being or has been directed by the water jets, a water recovery tray, for location beneath the sides of the train, for collecting water running down the side of the train, a recirculation system, for recirculating water in the water recovery tray back to the water supply tank for reuse, and a filtration system, for filtering the water being recirculated from the water recovery tray to the water supply tank.

Abstract: A portable liquid dispensing apparatus is described, which comprises a battery, a heating element, a liquid reservoir, a pump, an outlet, and a pipe, extending from the reservoir to the outlet and passing adjacent the heating element. In operation, the pump drives liquid from the reservoir into and through the pipe while the power source causes the heating element to heat the liquid passing through the portion of the pipe adjacent to the heating element to be expelled from the outlet at a temperature greater than the ambient temperature.
