Part of the new tram line to Mistrzejowice will run below ground level. On the route with a total length of over 1.2 km, passengers will find two underground stops – “Rondo Młyńskie” and “Rondo Polsadu”.

Going in the direction of Mistrzejowice, the tram will go underground just before the Młyńskie roundabout, it will cross it in a half-open trench, it will stop at the recessed “Rondo Młyńskie” stop, and before the Polsad roundabout it will enter a tunnel where the underground stop “Rondo Polsad” will be located. It will emerge to the surface before the Barei roundabout and continue towards Mistrzejowice on the surface.

Key figures:

  • The total length of the tunnel section will be 1230 m.
  • The largest difference in the level of the rail head in relation to the terrain will be approx. 12 m
  • The height in the tunnel, after deducting the space for the overhead contact line, will be 4.5 m.
  • The length of each underground platform will be 65 m.
  • The width of the underground platforms will be 4.5 m

The underground stops in the area of the Młyńskie roundabout and the Polsadu roundabout will be accessible by fixed and escalators, as well as elevators. In the underground spaces, platforms and places for getting on and off are planned, adapted for people with disabilities, including textured surface markings and tactile markings in the Braille language.

A visual information system in the form of suspended direction and information boards will be installed within all underground stops, enabling efficient movement of passengers in selected directions of travel.

In addition, the underground station at the Polsadu roundabout will be equipped with public toilets, including a separate toilet adapted to the needs of people with disabilities. A room for caregivers with children is also planned, equipped with a changing table and a feeding space.
