Intelligent Scheme Plan Sketch

(ISP – Sketch)

HICSE and the Network Rail Signalling innovations Group (SIG) have a long standing and collaborative relationship. HICSE developed the new ISP Sketch tool following a competitive tender award in 2016 and has gone on to develop a hosted version that will facilitate access to the tool Network Rail’s supply chain.  Sketch is central to the SIG group’s vision for a more automated signalling design process whether that’s providing the initial outline design for a new scheme or editing and validating changes to existing layouts.



Use ISP-Sketch to minimise errors, save time and reduce costs

ISP-Sketch provides graphical outputs for the assessment of design options and System Data Exchange Format (SDEF) output, enabled automated data entry and data sharing with other tools

  • Create scheme plan sketches from a library of signalling components
  • Analyse the safety and performance of signalling designs
  • Standardise the production of scheme sketches


Benefits of ISP-Sketch:

  • Increase signalling designers’ productivity by automatically transferring data between tools
  • Automatic drawing validation allowing users to check for basic errors and omissions, minimasing time allocated to works whilst improving quality
  • Improves the validation system and user experience, and saves time by eliminating the need to validate simple sketches
  • Improves the quality and consistency of sketches through use of common tool


Features and Functionality:

  • Output SDEF data for analysis tools Headway Analysis Tool (HAT) and signal spacing model (SSpaM)
  • Can be configured in-house to cater for the introduction of new signalling equipment types through NR’s cell library
  • Intuitive and interactive interface
  • Options and stage-works can be displayed within the same sketch using timeframes
  • Timeframe comparison to show red and green work
  • Export sketches as JPG images


What’s new:

  • Several types of objects can now display chainage labels such as bridges, tunnels, level crossings and gradient markers
  • Track splitting allows new junctions to be created at locations taken from a survey or calculated from other object positions
  • Several types or track-attached objects now have an editable ‘name’ field which will appear as a label above that object
  • If a junction has a name, this name will now be displayed in the junction chainage indicator
  • Junction chainage indicators now follow the timeframe colour of their junction equipment
  • Bridge labels are now offset further so that the name does not overlap with the bridge graphics
