WSP’s rolling stock teams are embedded within a broader rail business and beyond and work collaboratively to develop solutions that integrate rolling stock, infrastructure, systems and operations.

Given our breadth and global reach, we can offer rolling stock project deliveries of all sizes and degrees of complexity, across the rolling stock lifecycle. We have helped clients in countries such as Denmark, Norway, Finland, Sweden, the UK, the US, Canada, and Australia prove feasibility, procure and manage delivery of their next generation trains, and have assisted in managing, maintaining and optimizing the operational use of their assets in places like Singapore, Hong Kong and New Zealand.
