Railway Wheelsets: History, Research and Developments

Abstract

The paper describes the history and the architecture of trailing railway wheelsets.
\nImprovements in the design are described as well, showing remaining unsolved
\ncriticalities. Scientific literature on the subject is analyzed, highlighting the wide
\nimportance that axles still hold. Some relevant accidents resulting from of wheelset
\nfailures are described. A novel design of a wheelset studied to improve safety,
\nreduce maintenance, and reduce LCC, is introduced.
