DB Engineering & Consulting GmbH is the internationally operating engineering and consulting enterprise of Deutsche Bahn (DB), Europe’s largest railway operator and infrastructure manager. Originating in 1966 as Deutsche Eisenbahn-Consulting GmbH (DE-Consult) and later operating as DB International, the company merged with DB ProjektBau in 2016 to form DB Engineering & Consulting. Today, it forms the core pillar of the DB E.C.O. Group (Engineering, Consulting, Operations) alongside DB International Operations, infraView, and ESE.

With over 6,000 railway engineers, systems architects, and consultants operating from Berlin and offices in more than 85 countries, DB Engineering & Consulting provides end-to-end services across every phase of the railway lifecycle. Their portfolio spans preliminary studies, detailed alignment design, structural engineering, environmental permitting, construction supervision, system commissioning, and operations optimization. Backed by German high-speed railway expertise (ICE network) and extensive regional rail networks, DB E&C acts as lead advisor for both national rail modernization and complex cross-border corridors.

The firm is an industry pioneer in the implementation of the European Train Control System (ETCS Level 2 and 3), digital interlockings (DSTW), digital asset health monitoring (via DIANA geomonitoring), 3D multisensor mapping, Building Information Modelling (BIM), and sustainable traction systems (electrification, battery, and hydrogen rail alternatives).
