Modernization of Hanover Main Station, Germany

Hanover’s main station is to be modified and expanded to meet urban planning requirements, handle higher levels of traffic, and deliver what today’s passengers need from a modern, barrier-free and user-friendly train station. The renewal project for the station covers all of its structures and systems, which have been evolving for over 150 years: Transportation, engineering, and buildings. It involves the complete overhaul of the station’s 59 engineering structures underneath the six platforms, the renewal of platforms and their roofs, the drainage system, access facilities (6 elevators and 12 escalators), technical equipment, and buildings (kiosk, station attendants’ room). In addition, the designers have also established access for bridge inspection activities as part of an inspection plan.
