A system and method for the precise application of brake sand or other material to the rails of a railroad. In embodiments, a sand nozzle having a convex shaped air channel is used to provide a high speed jet of air for applying sand to the rail. The air channel further acts to create a low pressure area beneath the nozzle, thus preventing the nozzle from becoming clogged with sand, dust, moisture, oil, or other debris.
