Route Strategies for National Rail Infrastructure Operator

For a national rail infrastructure owner and operator, we provided analytical support to ascertain the various (route capability, route capacity, and journey time) impacts of investment in rail infrastructure on train operations.  Our primary tasks included calibrating a sketch-level train-performance model using field-collected data and limited outputs from a more expensive engineering model; interpreting prevailing signalling rules and achieving an understanding of existing hardware to ascertain maximum practical and theoretical line capacity; conceptual design of alternatives for infrastructure alterations to relieve identified bottlenecks; and cash flow analyses to ensure that the proposed enhancement schemes fit within the envelope of available budget.  Some of the ideas we identified have resulted in investment, although not always in the form initially envisaged.  The strategic route investment planning process continues on a cyclical five-year basis.
