  • Constantin Ciobanu
  • Steventon Bridge: Using FEA simulation techniques to move beyond rules-based OLE design (Garry Keenor, Atkins)

    The talk will cover ​the problems faced by the Great Western Project at Steventon Bridge, and the sequence of events and constraints that led Network Rail to impose a 60mph on electric trains on an otherwise 125mph railway. It will describe the OLE-pantograph analysis techniques now available to the industry through Atkins’ D-RSS modelling system, and how these were applied by Atkins and Network Rail to the Steventon problem to successfully demonstrate the actual electric speed limit of the OLE through the bridge. The talk will describe the resulting train tests, and how they validated the modelling predictions. The talk will conclude by describing how the electric speed  limit was raised from 60mph to 110mph, and the potential of dynamic modelling approaches for other projects as part of cost reduction in electrification.

    Areas to be covered include:

    • The geography of Steventon and the resulting OLE conundrum
    • The sequence of events leading to a 60mph electric PSR
    • The development of the D-RSS modelling tool
    • The application of D-RSS to Steventon
    • The use of physical test results to refine the D-RSS model
    • The resulting modelling predictions
    • Physical testing and the use of rapid analysis techniques
    • Final outcomes for GW
    • Implications for cost reduction in electrification
