Summary
👤
Senior🎓
Top SchoolKarl Berger is a Principal electrical engineer with decades of deep expertise in the specification, design, testing, and commissioning of rail transit vehicles across all modes—from heavy rail and commuter cars to light rail, streetcars, and automated people movers. He has led major procurement and independent engineering efforts for transit agencies, developed early inverter-drive demonstrations that helped modernize North American propulsion systems, and created one of the first Windows-based train performance simulators. Licensed as a Professional Engineer in multiple states, Karl combines hands-on propulsion and auxiliary systems design with program- and office-level leadership roles. He consults through Berger Engineering, providing practical problem analysis and commissioning support informed by prior senior roles at firms including Lea+Elliott and Parsons. Based in the Washington DC–Baltimore area, he pairs institutional transit knowledge with hobbyist maker skills developing Arduino and ESP32 projects, reflecting a continual hands-on curiosity about embedded electronics.
