Our approach
PROSE has developed a workshop-compatible auxiliary bogie for temporarily relocating low-floor vehicles during maintenance work. The design is deliberately kept simple and allows the vehicles to be picked up without twisting. The aim was to create a solution that is functional, robust and at the same time designed in such a way that it can be manufactured and used independently by the operator. PROSE was responsible for the complete design – from the concept to the production-ready documents.
PROSE has a close relationship with Würzburger Straßenbahn GmbH (WSB), which has developed over the last few years through various successful co-operations. We were able to start designing the bogie quickly thanks to our familiarity with the technical requirements of the WSB fleet.
Our approach was to quickly determine the wheel diameter and by confirming the chosen parameters with the customer. This allowed us to move directly into engineering with a clear, shared understanding.
Throughout the 3.5-month design phase, we kept the process lean and efficient. Monthly status updates ensured the customer remained well-informed without requiring intensive involvement. Thanks to PROSE’s broad technical expertise, unnecessary iterations were avoided, contributing to an timely project delivery.
Customer benefit
Thanks to our close collaboration with the customer and our deep technical understanding, we were able to start development particularly quickly. The customer benefited from our in-depth expertise and understanding and was able to save a lot of time and effort. The solution was tailored precisely to the requirements of the workshop. The complete production-ready documentation, including 3D model, proof of strength and track guidance report, ensured rapid realisation. Thanks to our comprehensive and in-depth knowledge of industry standards, the conditions in the WSB workshop and close collaboration with the customer, we were able to anticipate challenges before they arose.
