OCY Technologies provides full-lifecycle engineering and technical support for rail infrastructure, signaling, and control systems—from design through maintenance. The company's technical stack (AutoCAD, CATIA, Revit, Siemens TIA Portal, WinCC) reflects a hardware-heavy, capital-project operations model rather than software development. Current work spans major French rail programs (Grand Paris, Charles de Gaulle Express, EOLE) and rolling stock modernization (TGV2020, hybrid TER integration, metro bogies), with notable internal pressure around margin management and industrialization of new-build platforms.
