 Press Releases

  •  American Traction Systems, Inc. has designed propulsion software that has met the stringent EN50128:2011 standards for railway control and protective systems.  Following the strict guidelines of the standard to meet SIL2 Safety Integrity Level, the independent software assessor, Aegis Engineering Systems LTD, deemed the software “fit for its intended application” on the rail grinder MoW project to be used in the United Kingdom by Network Rail.  ATS developed and supplied the propulsion system, controllers, and software installed on the C44 MoW rail grinder built by Loram Maintenance of Way, a leading supplier of track maintenance machinery and services around the world.

    Juan Pinzon, ATS General Manager, and Project Manager and Validator for the project, said, “An enormous amount of time, energy, and resources went into achieving this standard, which has really built our technical confidence to handle this kind of project.  Our dedicated teams of engineers, designers, and technicians have shown their technical skills and attention to detail are more than ready for the global markets and the rigorous safety qualifications required.”

    About ATS: American Traction Systems is an American owned company based in Ft. Myers FL.  Founded in 2008 as an offshoot of its sister company, Saminco International, ATS has spent the last 10 years developing and manufacturing propulsion systems, controls, and accessories for the rail, light rail, hybrid vehicle, and marine industries. ATS has also received certificates from ABS, Lloyds of London, and the U. S. Coast Guard.
