Eminox has a strong heritage in rail. We have designed and manufactured exhaust aftertreatment systems (EATS) to suit Original Equipment Manufacturer (OEM) and retrofit solutions for nearly 30 years and are accredited to the world standard for rail welding – BS EN 15085-2:2007 CL1.

Our experience in delivering rail emission reduction solutions to rolling stock leasing companies and train manufacturers sees harmful emissions reduced by over 80% including particulate matter (PM), Nitrogen Oxide (NOx, NO2), Carbon Monoxide (CO) and hydrocarbons (HC) from the rail network.

Working with legislative bodies across the globe, our rail EATS bridge the gap to net zero by extending rolling stock life or, by developing pioneering solutions which support the latest global emissions standards.

OEM Tier 1 and Tier 2 solutions

Eminox emissions reduction technologies offer the rail industry full compliance to the latest global legislative standards. Our expertise in the design and development of scalable exhaust aftertreatment systems, complex and insulated pipework, and ancillary products ensures rail industry requirements for safety and quality are matched.

Our strong heritage in rail has seen us supply OEM including Bombardier and Hitachi with stainless-steel exhausts, insulated pipework and aftertreatment systems. Subsequently, these are widely used on diesel multiple units (DMU) and rail cars throughout the world.

Our research into the integration of dual and alternative fuels into the rail industry, and our expertise in designing, engineering, and manufacturing EATS ensures we deliver pioneering emissions solutions which meet current and future global emissions standards.

Cost effective and sustainable upgrade solutions

Eminox rail emissions reduction technology is a tailored retrofit solution which reduces harmful particulate matter (PM) and nitrogen oxides (NOx, NO2) from diesel railcars and on Diesel-Electric trains as part of a bi-mode train conversion. We help achieve environmental sustainability for passengers, employees and the surrounding communities.

This solution can be deployed on class 158/159 diesel multiple units (DMU) with similar innovative solutions developed for class 170 DMUs and enables older in-service vehicles to meet Stage V equivalent emissions standards thereby extending the lifetime of the vehicle and achieve near zero emissions in advance of the electrification of more railways.

At Eminox, we create partnerships for better air quality across the globe by working with businesses, governments, and industry specialists. Our retrofit rail emissions reduction technology provides an economical route to compliance.

We also proudly supply high quality insulated piping and  DEF tanks to bring a more comprehensive solution to both OE and retrofit rail projects.
