Hitachi has a suite of simulation tools that can be used in a wide variety of scenarios to include training and design validation to ensure that planned new and/or improved engineering works will deliver the desired system performance improvements.
Dessan enables the creation of rough designs ‘sketches’ of schemes to be created and edited quickly. This drawing tool is used in the early stages of a project when different options for signalling layouts are being considered. It is used to draw an initial design by providing a simple canvas and a palette of items that can be dragged onto the drawing. The tool provides a validation to check for basic errors in the design and a valid diagram can be exported to System Data Exchange Format (SDEF) for use in other tools.
TREsure is an application that can comprehensively test railway signalling interlocking data throughout the design process. It will provide an assurance that the interlocking data as written is validated against generic UK Railway Standards to ascertain any areas of unexpected results.
The process for this validation begins with the collation of the client provided scheme plan information, routes, and data into a virtual infrastructure model. This then forms the ‘host’ for the TREsure software which will create its own Excel format control tables independent of the Client provided Control Tables. Using the virtual infrastructure models in conjunction with adjacent interlocking areas, cross-boundary faults can be identified and eliminated as well as checking the focus of interlocking for any errors.
TREmodel In addition to being an extremely powerful and flexible training tool, this software is also used to evaluate major project designs prior to implementation. By using complex modelling techniques the exact signalling infrastructure of any part of the railway network can be replicated including mainline, station areas, yards and depot facilities. Options can then be changed in a virtual way to fully test the integrity of the design.
Additionally, our advanced data communications protocols mean that novel regulation and supervisory systems such as Traffic Management can be tested in the simulated environment for prototyping and proof of concept without affecting operational safety.
TREsim is designed to link to various VDU signalling systems and NX panels and is used to train and assess railway signalling engineers.
An Assessor’s workstation allows a large number of scenarios to be developed which can range from a basic introduction to a new system to a challenging incident for the most experienced signaller.
An accurate infrastructure model is created which uses train performance data to generate “virtual trains”. Real interlocking data is used wherever possible and, as all indications are generated in a realistic manner, the signalling control system assumes the simulator is the live railway. This high level of fidelity provides an extremely powerful and flexible training tool. All training sessions are automatically recorded and can be saved to provide proof of competency.
Hitachi provide numerous consultancy services across the rail signalling and control spheres. We also offer support for legacy systems as well as on site and off site training and testing facilities.
Support for Legacy Systems
Hitachi specialist engineers provide rail signalling consultancy support throughout the UK and overseas under licence for specific legacy systems, notably the Bombardier Transportation TEML41 telemetry system.
On Site and Off Site Training and Testing Facilities.
We offer onsite training as well as offsite training and testing facilities at our Bradford on Avon offices. Hitachi can build a realistic signalling environment based on all TREsim simulations produced, including IECC, WESTCAD, and MCS Workstations. These can be used for scheme testing purposes, Human Factors studies and additional training facilities prior to a new scheme commissioning.
