A moving performance that pleases the crowd
MW Industries, Inc. supports the development of springs and components for the fast-growing transit and freight market. Today, more and more population centers are investing in bus, train, and light rail services to provide efficient mass transit. We help meet this growing demand by working closely with transit and freight manufacturers to deliver important improvements in weight, ride comfort, performance, and reliability.

Better suspensions for a quieter, safer ride
Larger, faster, and more complex mass transit and freight systems demand improved suspension products. MW Industries is specially equipped to design, manufacture, and supply these oversized components, as well as deliver them to your facilities on time, every time. Light rail systems in particular demand springs and assemblies that offer quiet, comfortable, safe performance at high speeds. Based on the relationships we’ve built with leading transit and freight manufacturers, we have a proven ability to deliver a strong, light, and reliable system.

Transit and Bus Springs from MW IndustriesTaking the best innovation from other industries
Our long-term relationships with customers in markets like agriculture, construction, military, and motorsports have enabled us to take transit technologies to a whole new level of quality and performance. The design and production expertise we’ve developed in these other areas is particularly useful in developing new transit prototypes with some of the world's best materials. It also ensures that our customers remain on the cutting edge of the latest technological developments.

Empowering innovation for design solutions
MW Industries offers unique capabilities in producing high-quality, large-diameter springs. Based on this expertise, we recently helped one of our transit customers upgrade their rail suspension design by reducing weight and improving safety and reliability levels. We work closely with our customers to custom manufacture a wide range of wire forms, assemblies, compression springs, extension springs, torsion springs, and machined parts.
