Modelling and standardisation for railway infrastructure has attracted the attention from both academia and industry for a long time. Building Information modelling (BIM) derived from the area of building construction and is currently on the rise in infrastructure projects. However, in the domain of railway infrastructure, BIM is not advanced enough for productive use due to the lack of the railway specific requirements. In order to propose an effective modelling and standardisation technique for railway infrastructure, International Union of Railway (UIC) leads the RailTopoModel project. The RailTopoModel intends to be used in all business processes dealing with the design, construction, operation and maintenance of the railway infrastructure. The paper presents the details of RailTopoModel with one case study based on a railway network. The new dimension for the further development of RailTopoModel in the context of Product Lifecycle Management (PLM) is then presented. Finally, the implementation of the RailTopoModel and its new dimension into the PLM numerical platform is discussed.
