Faster from A to B
A 353 metre long, single-track railway tunnel is being built, which will pass under the existing railway tracks in Neu-Isenburg as part of the new Regional Tangent West (RTW) rail link.
As part of the RTW, the project improves regional connections and makes a significant contribution to strengthening local public transport in the Rhine-Main region. The RTW is a particular advantage for travellers and commuters in the heavily frequented Rhine-Main region.
