Summary
This paper concerns the high-level mechanical, electrical, and control requirements
for the proposed novel design of a railway track switch. The track switch is being
designed as part of the Repoint project, with the aim of investigating methods of increasing
railway capacity and improving network delay performance through the application
of technologies common to other industries. The basic mechanical design
of the novel switch is discussed. The mechanical considerations are discussed in the
context of the electrical and control system requirements, which are then investigated
and justified. For the electrical and control design, the requirements focus on the
functional performance, sustainability, fault tolerance and fault diagnostics. The requirements
presented in this paper are being used to inform the design of a laboratory
scale technology demonstrator, which will be completed by August 2014.
