Amsterdam's North-South metro - which operates as 'Line 52' - provides an 11km link from Amsterdam Zuid (South) interchange to the central district and continues on to the city’s northern reaches across the River IJ. It opened in 2018 after a decade of planning, design, construction and testing.
After joining the project in 2009 we provided technical support throughout its development, from infrastructure and traction power supply through to the replacement of aspects of the metro vehicles' safety systems with automatic train control (specifically, communications-based train control (CBTC)).
