For over 60 years ECM has been developing solutions and technologies for the safety, control and enhancement of railway infrastructures. ECM's modern solutions are important to the future of rail operations, and include state-of-the-art technologies, such as Computer Based Interlocking and Automatic Train Protection systems. In a move to remain on the leading-edge signal innovations for the rail industry, ECM has invested significantly in research and development, making it an attractive complement to Progress Rail's existing signal portfolio. In addition to systems, ECM also manufactures a broad portfolio of signal products, including power supplies, LED signal lights, axle counters, remote control and diagnostics, work site protection and other rail products.
