Wrocław – Poznan line is a part of additional connection PL/AD/102 of E-59 railway line Swinoujscie – Szczecin – Poznan – Wroclaw – Miedzylesie and is covered by TINA network.

In the Feasibility Study the following assumptions were made:

· Modernisation will cover the section of railway line from km 61 to km 160,9
  excluding Poznań and Wrocław nodes.
· Upgrading the line to the folowing basic technical parameters was assumed:
    · maximum  speed of passenger trains up to 160 km/h;
    · maximum speed of freight trains up to 120 km/h;
    · permissible axle load 225 kN;
    · minimum curve radius 1400 m;
    · ruling down-gradient to 12,5 ‰;
    · usable lenght of main basic lines and main additional lines (at least 1  track) - 750 m;
    · usable lenght of main additional lines 750 m;
    · structure gauge UIC - C1;
    · platforms according to UIC -741 with non-collission accesses at stations and at 
      passenger halts at track level with necessary protections measures and facilities for 
      the disabled;
    · upgrading of the line to bi-directional traffic on each track; 
    · railway traffic system with  remote control;
    · 4-aspect automatic block line;
    · traction network according to UIC-ORE-484/+p11/D sheets;
    · wire and wireless communication equipment according to UIC-735-2 sheets
      additional equipment to detect overheated axles or deformations of wheel circles;
    · upgrading of cross section of the track to normal section with drainage;
    · upgrading of engineering structures to the speed Vmax=160 km/h;
    · upgrading of power supply system to higher power consumption resulting from an
      increase in quantity and speed of trains.
· Liquidation of a number of stations  was assumed.
· It was assumed that remote control of RTC (sectional on inception stage and planned
   dispatch) will cover all remaining indispensable elements of infrastructure, that is
   lighting, turnouts heating, announcing of train comings, etc., at stations and
   passenger halts.
