NoBo and AsBo roles in renovation Zwolle, the second largest railway junction in the Netherlands
11 June 2020

In the weekend of 5, 6 and 7 June, major renovation work is carried out at Zwolle railway yard, the second largest railway junction in the Netherlands. This work is focussed on the commissioning of the fully renovated garaging area (RGS) on the south side of the yard between Windesheim University of Applied Sciences and the river IJssel. The garaging area is equipped with catenary and service platforms for the cleaning and minor maintenance of trainsets, and can from now on be operated from the control centre. In addition, as part of the two-year renovation work on the yard as a whole, the first part of a new train protection system (coupled iVPI) was put into service and new point switches installed in the main line. 
 
In preparation for this renovation work, Ricardo Certification, in its role as Notified Body (NoBo) and commissioned by Alliantie Zwaluw (a collaboration between ProRail and contractor Volker Stevin), carried out a study into the conformity of the designs with railway legislation and regulations. This led to the issue of two Interim Inspection Statements. In addition, Ricardo Certification, in its role as Assessment Body (AsBo), investigated risk management in the project. This renovation work could not have gone ahead without Ricardo’s positive recommendation that followed from this study. 
 
Between 2018 and 2021, a range of major renovation work will be performed in Zwolle. In addition to the renewal of RGS, the tracks at the station will be replaced by new rigid tracks in the summer of 2018. Some existing tracks are currently being upgraded by the addition of two extra tracks, and the contractor is building a ‘dive-under’ (at Herfte). The renovation work at Zwolle railway yard is part of the “Spoorplan Noord-Nederland” (North Netherlands Railway Plan) and will lead to a significant improvement of rail transport in North Netherlands and from the Randstad conurbation to North Netherlands.
