Testimonials

Our goal is to deliver on-time and reliably support to our clients throughout making technical decisions to improve interface performance and manage their electrification network.

“T-RIS have been instrumental in developing the UK rail industry’s understanding of the critical pantograph/overhead contact system interface.  By developing finite element analysis tools to model the interface we are now in a position to challenge traditional thinking, apply novel solutions to challenging technical problems and analyse data collected from site to improve asset management.  As the need for significant electrification increases globally to meet climate change challenges, the use of digital tools and ability to process data effectively will be central to improving efficiency and driving down costs.  T-RIS have the opportunity to be a significant player in railway electrification and data management in the digital, low carbon world.”

“T-RIS have provided the technical solution and direction on which OLE Stat has been based. They have been an integral part of the development process providing not just industry leading technical expertise but innovative strategic thinking along the way. On a personal level the team are accommodating, easy to work with and honest. They will remain a key component going forward with OLE Stat and are a key supplier in our journey towards a digital future.”

“Working alongside T-RIS for construction assurance to K2C Midland Mainline Electrification has provided SPL and clients with unprecedented confidence every step of the way enabling a safe commissioning of rolling stock to the new high speed network. Nikos has been a key link to analysing data and generating the construction assurance and system validation reports, managing to gain an unprecedented clean authorisation with no conditions for the 40km / 192STK of newly electrified network.”

“T-RIS and Nikos have been instrumental in providing insightful and expert technical solutions for the Sydney Metro project. The use of D-RSS software and the technical rigour with which Nikos was able to interrogate the root-cause and underlying interface issues provided invaluable outcome for the project. Nikos was able to breakdown complex technical concepts and articulate in an easy to understand manner which supported and enabled decision making within Sydney Metro.”

“The operational performance of the interface between pantograph and OLE is a vitally important issue. Laboratory testing and test results from instrumented pantographs operating at line speed have helped in allowing development of OLE and pantographs for high speeds.  

The development of those systems across the 20th century had some laboratory testing and then testing by instrumented pantographs to verify designs. As systems evolved design rules have been defined, largely from empirical reasoning. 

Nikolaos Baimpas has applied his considerable abilities in modelling and simulation and to investigate these issues. Through establishing the co-relation between known design features such as registration points his advanced methods allow data from instrumented pantographs or static non-contact measurements gathered by test trains to be interrogated in fine detail. This completes a detailed model of the OLE. Combined then with an equally detailed model of the pantograph this allows simulation results to be generated allowing the variables in operation pre conditions or parameters to be tested. A spectacular success on the GW Main Line allowed the design rules for wire gradients to be challenged. The direct result of that simulation work made possible avoidance of a severe speed restriction which conventional wisdom would have required. 

The techniques that Nikolaos has developed will undoubtably continue to push out the boundaries of what is possible, and will be instrumental in securing more reliable performance of electric railways.”
