    • Atmospheric Ice Accretion on Railway Overhead Powerline Conductors- A Numerical Case Study 

      Lotfi, Arefeh; Virk, Muhammad Shakeel; Pettersen, Jan-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-16)
      Ice accretion on railway overhead contact wires/conductors can cause various critical operational and safety issues such as overloading, arc formation, mass imbalance, and wire galloping. The focus of this multiphase numerical study is to understand and analyze the ice accretion physics on railway overhead powerline conductors at various operating conditions. In this regard, two different ...

    • Railway operations in icing conditions: a review of issues and mitigation methods 

      Lotfi, Arefeh; Virk, Muhammad Shakeel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-14)
      This article focuses on studying the current literature about railway operations in icing conditions, identifying icing effects on railway infrastructure, rolling stock, and operations, and summarizing the existing solutions for addressing these issues. Even though various studies have been conducted in the past on the impact of winter, climate change, and low temperatures on railway operations, not ...
