Transco narrow-gauge railway of the NEAT building site in Sedrun. The entrance - not to the new Gotthard base tunnel (that's in Erstfeld), but to the access tunnel to a vertical shaft which allows to build the tunnel from the middle (and will, once the tunnel is finished, be used for ventilation and as an emergency exit or even a regular station).
