Dr. Alfredo Núñez Vicencio – Research Projects

IAM4RAIL project. Duration: Dec. 2022 – Nov. 2026. Keywords: Railway Infrastructure, Onboard Monitoring, Moving Loads, Track Stiffness, Adhesion Management, Embankment Stability. TU Delft is Affiliated Entity of ProRail in this project. TU Delft project leader: Dr. Alfredo Núñez. Role: Research and coordination, WP9 Railway Infrastructure leader, Cluster D Infrastructure co-leader. Consortium: ADIF (Project leader, Spain), ALSTOM (France), MERMEC (Italy), AZD (Czech Republic), CAF (Spain), CEIT (Spain), DB BAHN (Germany), DLR (Germany), CEMOSA (Spain), COMSA (Spain), Enyse (Spain), Tekniker (Spain), Faiveley Wabtec (France), Ferrovie dello stato Italiane (Italy), Hitachi Rail STS (Italy), indra (Spain), Talgo (Spain), Jernbane-direktoratet (Norway), Knorr-Bremse (Germany), OBB (Austria), PKP (Poland), ProRail (The Netherlands), NS (The Netherlands), SIEMENS (Germany), SNCF (France), Strukton Rail (The Netherlands), Thales (Germany), Trafikverket (Sweden), and Voestalpine (Austria).

In2Track3 project. Duration: Jan. 2021 – Jan. 2024. Keywords: Railway Infrastructure, demonstration of monitoring technology, intelligent railways. TU Delft is a third-linked party of ProRail in this project. TU Delft project leader: Dr. Alfredo Núñez. Role: Research and coordinate the inputs, task 3.4 leader about simulations and railway track monitoring. We worked 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 focused 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.

  • Project sponsored by Thailand Government. Duration: Sep. 2018 - Sep. 2022. Keywords: Railway track measurement, track stiffness, acceleration signals. TU Delft project leader: Dr. Alfredo Núñez. Role: Daily supervisor of a PhD researcher, Siwarak Unsiwilai.

    • Needs Tailored Interoperable Railway NeTIRail-INFRA(Cordis details), Call H2020-MG-2014 Two Stages, Topic MG-2.1-2014 - I2I Intelligent Infrastructure. Duration: 36 Months, Jun. 2015 - Jun. 2018. Keywords: Rail, track, overhead power supply, smart technology, societal impact, economics, decision support tools. TU Delft participants: Dr. Zili Li and Dr. Alfredo Núñez. Consortium: The University of Sheffield (Project leader, UK), University of Leeds (UK), International Union of Railways - UIC (France), ADS-Electronics Research (Romania), Romanian Railway Authority - AFER (Romania), Delft University of Technology (The Netherlands), Albert-Ludwigs University Freiburg ALU-FR (Germany), IFSTTAR (France), TCDD (Turkey), INTADER (Turkey), VTI (Sweden), SZ-Infrastruktura (Slovenia), RCCF (Romania). 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.
