The Chicago Tunnel Company built a 2 ft (610 mm) narrow gauge railway freight tunnel network under the downtown of the city of Chicago. This was regulated by the Interstate Commerce Commission as an interurban even though it operated entirely under central Chicago, did not carry passengers, and was entirely underground.
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.

Long term ground movements above a tunnel may continue to increase with time after tunnelling in clayey soils as the tunnelling-induced excess pore water pressures dissipate, whilst the changing earth pressure acting on the tunnel leads to further tunnel deformation during consolidation.
