OGAB® RAIL Advanced TRS®

Utilising patented Active Flow Control technology, Ogab® has developed a breakthrough system that decreases aerodynamic drag on trains to reduce fuel consumption by more than 10%.

Ogab® has achieved a 22.34% reduction in drag force whilst making our trains kinder to the environment. Powered by energy that would otherwise be lost, our Advanced TRS® technology yields an 11% reduction in fuel consumption helping to cut C02 emissions and significantly reduce running costs.

Our Advanced TRS® tests with new and modified technology within the rail industry shows a promising future for our safe, reliable and sustainable innovations.

The majority of inter-city transportation of passengers is via trains. As a result, rail transport is responsible for a significant portion of both fuel and electricity consumption as well as CO2 emissions.

Class 220 Voyager trains, which are used in large volumes across Britain’s railways, achieve speeds of 130 miles per hour as a result of their streamlined body. The trains need to be as aerodynamic (minimal wind resistance) as possible.

With Advanced TRS® we can achieve a 20% reduction in drag forces. Consequently, these trains can achieve faster speeds, further reducing travel time of this transport while saving energy and lowering emissions.

At Ogab®, our Active Flow Control drag reduction system has led to substantial reductions in drag force with the value of 22.34% mitigated for a Class 220 Voyager type train.

This results in a 22.39% reduction of the drag coefficient for a train compared to those without our Active Flow Control technology.

How It Works.

This significant reduction in drag coefficient not only increases the speed of the train, but it also achieves an incredible fuel saving of over 10%. This results in a huge saving in cost as well as less fuel-related CO2 emissions, heavily reducing the environmental impact of our rail networks. 

Implementing our Advanced TRS® system can make train services run more efficiently and at a lower cost too.

This reduction in cost could mean more affordable travel for passengers. This is particularly important in a market where customers are feeling the financial impact of year-on-year ticket price increases.

Furthermore, with Advanced TRS®, the pressure field surrounding the train is significantly improved. This enhances the overall stability of the train and the comfort of travel, adding to the customer experience.
