Area East - Realization of Improvement Measures Zwolle-Enschede contract Wierden
This non-public negotiated procedure by ProRail B.V. concerns the realization of improvement measures on the railway network between Zwolle and Enschede, specifically at the Wierden yard. The objective is to increase the transit speed of the IC Zwolle-Enschede from 40 km/h to 80 km/h. To achieve this, the 1:9 crossover switches west of the station will be replaced by 1:15 crossover switches, the 1:9 switch on the east side (track 3) will be replaced by a 1:15 switch, and two 1:9 switch crossovers on the east side will be decommissioned. Additionally, the layout change requires the replacement of a large part of the overhead line system, implementation of a new train detection system (replacing PSSSL with axle counters), and replacement of the B-Relais interlocking with iVPI. The assignment includes various track systems and must comply with the ProRail Recognition Scheme (EP2019) and European regulations. The tender is aimed at specialized railway contractors with experience in switch and interlocking installations, overhead line and detection systems.
