scope:

This document provides general information on point operating equipment and associated ancillaries that are in use on Railtrack's Infrastructure.

PURPOSE

This document provides general information relating to point operating equipment used on Railtrack's Infrastructure, together with technical information and where appropriate related historical background.

Note: the clamp lock section which once resided in this Code of Practice has been transferred to RT/E/C/11774 (Clamp Lock Handbook). The longer-term objective will be to extract those sections that are point machine specific to form separate Codes of Practice for individual point machine types (WBS & Co: M2, M3, M3A, Style 63 and ALSTOM HW point machines). In the interim however, and to allow the expedient issue of information, this SIGTAN will be used as a stop-gap for information relating to any point machine type (including clamp locks), to be incorporated later into a Code of Practice where one exists.
