Gateway Gardens in Frankfurt am Main, receiving suburban train connection, Germany

The new Gateway Gardens neighborhood is being developed on repurposed land in Frankfurt. Now the area is being connected to local and regional public transportation. For this project, DB Engineering & Consulting was commissioned to provide design services to connect the DB line running between Frankfurt (Main) Stadion station and Frankfurt (Main) Flughafen regional station to an underground suburban train station in Gateway Gardens, as well as to provide construction management services.

The electrified double-track line is 4 km long and almost half of it runs through tunnels. The tunnel cross section is square and has a clear width of 11 m and a clear height of 7 m. The tunnel’s dimensions fall short of the standard cross section, and a corresponding permit has been obtained (case-by-case approval). The tunnel has been prepared for open construction. The line is located in water reserve zones III and IIIa, and on the edge of a special area of conservation, meaning that German conservation law prohibited lowering the groundwater level.
