Rail Drainage

Modla, ARUP, and network rail develop drainage system model

Brief

Modla was engaged by ARUP to develop a drainage model for Network Rail (UK). The model was to assist with capital and maintenance planning, as well as demonstrating the scalability of Modla's knowledge capture framework.

Asset Models

For this project, a drainage model was facilitated with the subject matter experts from Network Rail and ARUP. The contents of the model included: components, failure modes, decision layers, inputs, tasks, events, costs, and the causal relationships between these elements. The model was developed over multiple workshops for a particular site, with the intention to roll it out regionally, and then nationally.

Solvers

The solvers used included an As-Is (Current State) solver, a Fixed interval Strategy Optimisation, and an implementation of Network Rail's risk policy. These three solvers were used to generate various scenarios for comparison.

Outputs

The outputs were displayed using Power BI, and an RCM templated word document for each drainage system was generated using an automated process.

Conclusion

This project proved the scalability, and capability of a Knowledge-First architecture and gained process buy-in from the stakeholders. Other asset classes and use cases are now under consideration for applying this process.
