A system for cleaning vehicles, such as train cars, locomotives, buses, and large trucks, of various outer configurations, with optimum cleaning of each vehicle regardless of outer configuration and without use of brushes. The apparatus includes a prewet station, a wash station and a rinse station. The wash station has several conduit arches, each with an engineered nozzle arrangement that provides a specific impact angle in the order of about 80 degrees and a specific impact pressure in the order of from about 0.3 to about 0.5 psi of the washing liquid on vehicles of a specific configuration. The rinse station likewise has several conduit arches, each with an engineered nozzle arrangement that provides a specific impact angle in the order of about 80 degrees and a specific impact pressure in the order of from about 1.5 to about 2.0 psi of the rinse liquid on vehicles of a specific configuration. Each arch is shaped and sized to allow passage of the largest vehicle to be cleaned. The nozzle placement and design vary from arch to arch at the wash station and at the rinse station, and each arch provides a specific liquid spray pattern, including a specific impact angle and a specific impact pressure on vehicles of a particular associated configuration. At the prewet station each vehicle is sprayed by a prewet liquid which serves primarily to being the vehicle surface to the desired temperature, and so a single conduit arch with nozzles designed for a general overall spray pattern is provided at the prewet station. The liquid runoffs from the prewet station, the wash station, and the rinse station are collected and recycled separately. An operator determines the configuration of each vehicle entering the apparatus and activates the appropriate associated wash and rinse conduit arches. The equipment is housed within a building which can have air curtains at the building entrance and exit.
