Buses, trains, and large commercial vehicles have different maintenance needs than consumer vehicles. Just as they have different mechanical needs, they have different washing needs, as well. Often used in harsh conditions and exposed to elements, these vehicles require a dedicated train wash or transit cleaning system to handle the contaminants they pick up.

Systems to Tackle Tough Grime

While N/S Wash has been keeping personal vehicles clean for more than 50 years, we are committed to bringing that dedication to transit fleets. Our train wash systems are used by operators worldwide and our customers include some of the largest transit and fleet organizations. It is through this work that we have developed the expertise and innovation that can benefit your transit fleet through hundreds of thousands of wash cycles per year.

To aid fleet operators we’ve broken down our transit wash systems into three categories: buses, trains, and large commercial vehicles. That way you can quickly find the system that fits your fleet’s needs.

Whether you invest in a train wash or another type of bus or transit wash, you can be assured that each model is designed to tackle the tough grime unique to heavy duty vehicles while being highly efficient enough to cut down on wash time and ensure vehicles get back in operation faster. If you have a fleet in need of a heavy duty cleaning, trust N/S Wash.
