TransPennine Route Upgrade

As part of the Network Rail Group Digital Railway ECI (Early Contractor Involvement) work-streams, Hitachi was engaged to run specific digital simulations of the TransPennine geographic area, specifically York to Manchester in both directions. 

The remit covered:

  • Modelling ETCS level 2 for the whole route
  • Recommending an optimal route strategy for assets and timetabling
  • Supplying rolling stock specific timings and estimates against revised route asset improvements
  • Recommending specific ETCS, civil, ATO and TMS deployment areas

Hitachi created an accurate infrastructure model that contained hi-fidelity signalling interlocking, gradient, permissible speeds, stations and junctions.  In addition sectional running time data was overlaid with accurate rolling stock parameters for Hitachi’s own Class 802 bi-mode train and Class 185 stock, this included full braking and accelerating characteristics.

The Hitachi team used both the information provided by NR and existing local knowledge to deliver a route wide simulation to a high degree of accuracy.  Real time TRUST data was also compared for rolling stock to establish average disruption free timings and measured them against the same parameters within the model.

The accuracy of the model was ensured through manually running the timetable for 5 separate areas by an experienced Signaller where possible.  We baselined the tool by running the existing TPE 2017 timetable and the outputs were verified to a + / - 30 second variable which is less than 1% variation from optimum.

The outcome of the modelling allowed stakeholders to clearly identify potential opportunities for improvement and informed where performance initiatives or infrastructure interventions should be focused for maximum impact, whether in terms of investment or mitigation.
