Crown Cess Posts are permanently installed at trackside on a concrete or pile foundation. They are available in heights to suit the specific location and signal requirements. The Crown Cess Post is positioned to attain equal distance between the centre-line of the signal head and track and the centre-line of the post and track. The Post design provides robust support for various combinations of signal head equipment. The function of the post is to provide improved safe access to the signal head equipment for maintenance purposes. The post is relatively maintenance-free and incorporates a number of ‘duplicated’ safety features to safeguard personnel and equipment when carrying out maintenance activities. The post is designed to comply with British Standards, BD51/98 Portal and Cantilever Sign and Signal structures, and relevant Railway Group and company Standards.
