IN2TRACK3: we are very happy to work as third linked party of ProRail in the Shift2Rail project IN2TRACK3. We will be working together with my colleagues from TUDelft Zhen Yang (tribometer), Chen Shen (track stiffness), Jan Moraal (ABA), Jurjen Hendriks (ABA), the professors Zili Li and Rolf Dollevoet, partners from ProRail including Arjen Zoeteman, and partners from Trafikverket in Sweden. Our work will focus on three challenges: 1) demostration of ABA based rail defect detection in a freight dominated line in Sweden (Iron Ore Line), 2) further development of a new tribometer using our V-Track, and 3) development of track stiffness estimation techniques. Information from this project can be found here: IN2TRACK3 and Twitter.


Demostration and final conference H2020 Project NeTIRail: we extended the capabilities of ABA measurement to detect defects under different speeds and monitored a regional railway line with a passenger train that was in operation. We also investigated switches and crossings, rail waves, and corrugation. Other videos in the youtube channel of the project.

Abril 1, 2021, together with colleagues from Pavement and Railway Engineering, Anupam Kumar, Katerina Varveri, and Zhen Yang, we are organizing a special issue about the topic Monitoring Transportation Infrastructures in the Open Access journal Materials - MDPI. Please do not hesitate to contact me if you have any question about the special issue.

December 16, 2020, I presented our work on multiobjective optimization for railway maintenance in regional railways, at the 2020 Big Data Conference organized by the University of Delaware. The slides are available here PDF, and the video of the presentation is next here:




December 1, 2020, Dr. Hongrui Wang started his tenure track period as assistant professor in the field of Artificial Intelligence for Engineering Structures, at Delft University of Technology.

November, 2018, I am a visiting scholar at the University of California, Berkeley for three months. Funded by the H2020 project RISEN. I had the chance to interact with many colleagues, in the photo with Prof. Carlos Daganzo.


October 20, 2018, invitations to CM2018 special issue of the journal WEAR were sent on Saturday. The remit of the Wear Special Issue is narrower than the conference (only about 50 papers can be accepted); thus, some very good papers could not be selected for this volume, though some of them might be selected for Journal of Rail and Rapid Transit and Tribology: Materials, Surface and Interfaces. The guest editors of the special issue WEAR are: Zili Li - chair CM2018 (Delft University of Technology, The Netherlands), Mats Berg (Royal Institute of Technology, Sweden), David Fletcher (University of Sheffield, UK), Paul Meehan (University of Queensland, Australia), and Alfredo Núñez (Delft University of Technology, The Netherlands).

October 19, 2018, I'm very happy to officially have concluded all my tenure track related agreements. Since November 2018, I'm assistant professor (universiteit docent) in the topic "Data-based maintenance for railway infrastructure".

July 11, 2018, for a term of two years I will join the editorial board for the journal Applied Soft Computing. The journal is Q1 with a current IF 3.907. The journal promotes an integrated view of soft computing to solve real life problems. The editorial board can be seen in this link: Editorial Board.

I had the chance to meet Paul Werbos, thanks to him we can train neural networks using backpropagation.




June 28, 2018, I participated in a seminar organized by Kivi: Machine learning with Big Data. A photo can be found in this link.

May 24, 2018, the final conference of the H2020 project NeTIRail-INFRA was held in Ljubljana, Slovenia. TUDelft participated mainly in two task: in WP2 with research about short pitch corrugation and in WP4 with research about deployment of ABA measurements using trains in operation. Here the links to the two presentations I did: (WP2 Corrugation), (WP4 ABA in Romania). You can find more videos about the project in the Youtube channel: NeTIRail-INFRA Youtube Channel. Overview of WP4 Monitoring and smart technology can be seen here WP4 NeTIRail-INFRA, and a summary of our tested ABA system in Romania here WP4 ABA.

January 5, 2018, we are organizing the 11th International Conference on Contact Mechanics and Wear of Rail/Wheel Systems (CM2018). The final deadline for abstract is 20th January 2018.
