Signalling Product Specifications: Electronic Treadle
|Publication Date:||2 June 2018|
These requirements apply to an electronic treadle system which is a functional replacement of existing electro-mechanical treadles installed on Network Rail infrastructure.
The purpose of this specification is to define the requirements of an electronic treadle system.
The treadle system is designed to:
a) be functionally equivalent to existing treadles; having no moving parts, greater reliability and reduced whole life costs;
b) reduce the risk of service affecting failures by providing predictive failure alerts; and
c) reduce the exposure to red zone working by requiring reduced maintenance and facilitating remote condition monitoring.
