Certification strategy for innovative freight wagon

We contributed to the development of a new type of rail freight wagon for use across Western Europe. This car carries a combination of technologies from several other types of rolling stock. By matching the technical characteristics of the new wagon with European and national requirements in an in-depth analysis, we developed a cost effective strategy for obtaining type approval. This startegy was presented to national and European authorities in a pre-enagement procedure and subsequently implemented. Managing a Notified Body was an essential aspect of this assignment.


Realisation of battery-powered hybrid locomotives

We were closely involved in realizing the first locomotives on battery technology in the Netherlands. These locomotives enable sustainable shunting operations and replace very outdated and polluting diesel-powered locomotives. We mediated in the contracting between the manufacturer and a freight carrier. We came up with an ambitious but realistic technical specification in an iterative manner and monitored the development and certification.


Tender support in a European tender for new rolling stock

We supported a major manufacturer with execution of a tender process. We were consulted on the bid strategy and the most appropriate technical solution(s). We then assessed quality and suitablity of multiple very diverse tender documents and adapted them where necessary.The assessment covered both highly complex technical topics (for example RAMS/LCC or certification) and process-related topics like project management. Also, more general aspects such as readability and conciseness of the documents was considered.
