Belden and Cylus are teaming on a rail cybersecurity platform for rolling stock and signaling systems. Also, Cummins’ Tier 4 QSK95 engine can now be used with renewable diesel; and Hitachi Energy is offering a new oil-free traction transformer with integrated cooling system.
The new Belden-Cylus cybersecurity platform brings together Belden’s EAGLE40-6M, an industrial firewall (NGFW), and CylusOne cybersecurity software that provides continuous monitoring and real-time protection for rolling stock and rail infrastructure, the companies reported on Sept. 20. Belden and Cylus noted that the “added layer of CylusOne atop Belden’s NGFW provides automated and scalable security controls to enable compliance with the latest rail cybersecurity standards, including CENELEC TS-50701. The combined solutions include deep packet inspection (DPI) of rail onboard and wayside protocols and provides contextual analysis, delivering both comprehensive threat detection and visibility.” The new platform, they said, can be deployed in both new and existing rail technology environments.
“We are excited to partner with Belden, the world leader in ruggedized networking solutions and firewalls for rolling stock,” said Miki Shifman, Co-founder and CTO of Cylus. “This solution will provide another robust layer of protection against cyberattacks, ensuring the safety and security of rail onboard and wayside systems.”
“We take the safety and security of our transportation customers with the utmost seriousness, and look forward to supporting Cylus in its effort to adapt the CylusOne software so that it runs on our NGFW, providing them with increased protection via this dedicated firewall developed specifically for the rail transportation market,” said Oliver Kleineberg, CTO of Industrial Automation and Vice President of Technology at St. Louis-based Belden.
The Cummins Tier 4 QSK95 engine can be used with renewable diesel, “without any negative impact to its current EPA emission requirements or reliability,” the manufacturer reported on Sept. 20.
Cummins said it partnered with Siemens Mobility on testing in an aim “to help customers meet their goal of running renewable diesel in QSK95-powered Charger locomotives to reduce emissions and [to] use a fuel with lower carbon intensity.” Hydrogenated vegetable oil (HVO) was tested on QSK95 Tier 4 fuel and after-treatment systems.
The chemical and physical properties of HVO, Cummins said, “are like those of diesel fuel, but its fossil-free composition and low carbon content provides a simple and efficient alternative to diesel. Importantly, HVO can be blended and used in any proportion with diesel, which allows for ease of transition.”
In tests, use of this renewable fuel vs. traditional diesel provided up to 13% additional reduction in NOx (Nitrogen Oxide); up to 5% additional reduction in DEF (Diesel Exhaust Fluid) consumption; and up to 50% additional reduction in PM (Particulate Matter) emissions, Cummins noted.
“Now being able to incorporate renewable fuel into Charger operations will allow our customers to make even more meaningful inroads into their sustainability efforts,” said Armin Kick, vice president of Locomotives and High-Speed Trainsets, for Siemens Mobility in North America.
Hitachi Energy has updated its RESIBLOC® Rail product. The new dry-type traction transformer with integrated cooling system is designed to reduce CO2 emissions and total operating costs, while increasing energy efficiency, the company reported on Sept. 21. First introduced in 2018, RESIBLOC® Rail offered a voltage rating up to 15 kV; now it has a voltage rating up to 25 kV.
“Traction transformers route power from overhead train cables to essential train functions like traction, lighting, heating and ventilation, brakes, signaling, and communication,” Hitachi Energy said. “They are installed on the train and are therefore also known as ‘on-board’ rail transformers. Dry-type (oil-free) traction transformers bring the benefits of high-level efficiency, people and environmental safety, lower maintenance, and failure rate reduction by removing liquid that brings potential risk and additional maintenance.”
“Dry-type transformers offer unmatched protection to people, property and the surrounding environment,” said Bruno Melles, Managing Director of the Transformers Business Unit of Hitachi Energy. “This pioneering RESIBLOC® Rail transformer technology developed by our world-class engineers will help accelerate a sustainable energy future for societies and the rail industry.”
