Renewal of a fixed railway track using UHPFRC - first use worldwide of UHPFRC in rail track construction, part 1

Antonina Hochuli

This two-part article reports on the renewal and adaptation of the fixed railway track in the heavily frequented underground train station at Zurich Airport. The fixed track built in 1980 had reached the service duration predicted by the system provider an ...

Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action

Eugen Brühwiler

Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...

Improving Railway Track Coverage with mmWave Bridges: A Measurement Campaign

Andreas Peter Burg, Adrian Schumacher, Ruben Merz

Bringing cellular capacity into modern trains is challenging because they act as Faraday cages. Building a radio frequency (RF) corridor along the railway tracks ensures a high signal-to-noise ratio and limits handovers. However, building such RF corridors ...

Mask to identify polluted periods during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Aerosol and trace gas measurements are strongly affected by the ship exhaust and other human activities (e.g., helicopter flights). Therefore, it is important to discriminate between clean and polluted periods. This mask provides an indication of clean per ...

Time calibration for the SciFi Tracker at SND@LHC using DESY testbeam data

Jennifer Maria Frieden

A Scintillating Fibre Tracker with timing information was developed by LPHE at EPFL. To evaluate its timing and tracking performance, a test beam campaign was organized at DESY in October 2019. By using this data, the different time delays and offsets that ...

Size distribution of interstitial and total particles between 18 and 660 nm collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The aerosol size distribution was measured with a custom made scanning mobility particle sizer (SMPS), range 18⁠ – ⁠660 nm. Aerosols are important for a variety of reasons, one of the most prominent is that a sub-set of the aerosol population can act as cl ...

Model-based economic analysis of electrification in railway - Understanding the impact of track, operations, and uncertainties

Michel Bierlaire, Nikola Obrenovic, Florian Mueller

This paper presents results on the impact of different tracks on the economic viability of track electrification for regional railway. Since regional railway still heavily relies on pollutive diesel propulsion systems, track electrification can be key to r ...
