Student Assistant in GPR-Based Railway Track Condition …, Zürich (Kreis 11)

Student Assistant in GPR-Based Railway Track Condition Assessment: Experimental Campaign Support Ground Penetrating Radar (GPR) is a non‑destructive geophysical technique with significant potential for assessing railway ballast and substructure condition, particularly with respect to fouling and moisture distribution. Understanding these parameters is essential for predicting long‑term track performance and planning maintenanceinterventions.

Project background As part of an ongoing collaboration between ETH Zürich, SBB (Swiss Federal Railways), and Terra Vermessungen AG, we are conducting controlled experiments on a dedicated test track, located at the ETH Hönggerberg campus, to systematically investigate GPR response under varying fouling and moisture conditions. By introducing degradation into pristine ballast under documented conditions, we aim to establish reliable ground truth data for developing automated condition indicators from GPR measurements.

Support in planning and preparation of the experimental campaign (test track configuration, material handling, measurement protocols)

Participation in on-site GPR measurement activities together with project partners

Laboratory sample preparation and material characterization (moisture content, fouling levels)

Data organization, quality control, and documentation

Signal processing and exploratory data analysis of collected GPR profiles

Duration and Start Date

Start: May 2026

Duration: May– July 2026 (approximately 3 months)

Workload: Flexible, to be discussed

Extension: Possible depending on project needs and candidate availability

Profile

Currently enrolled at ETH Zürich (Bachelor's or Master's level)

Practical, hands‑on attitude for field and laboratory work

Programming experience (Python preferred) for data analysis tasks

Availability for on‑site work during the experimental campaign (May‑June 2026)

We offer

Involvement in an applied research project with direct industry relevance

Hands‑on experience with GPR technology and railway infrastructure

Collaboration with academic and industry partners (SBB, Terra Vermessungen AG)

Flexible working hours compatible with your studies

Possibility of extension beyond July depending on project progress and mutual interest
