1630 WG - Overhead Contact Systems Structures Working Group

The IEEE 1630 Overhead Contact Systems Structures Working Group is active and part of the OCS Sub-Committee for Rail Transit Systems. At the present time there are no suitable standards governing structural requirements for supports used for OCS. The purpose of this working group is to develop a standard(s) to improve design efficiency for new and existing rail transit projects. The “Draft Standard for Supporting Structures for Overhead Contact Systems for Transit Systems" will go to ballot in the Spring of 2010. This standard determines minimum structural requirements for structural supports used for OCS for heavy rail, light rail, and trolley bus systems, including loading, safety factors and deflection. By standardizing or limiting the size, material and strength of supporting structures for OCS, economies of scale and reduction in overall stockpile requirements can be observed. It is the goal of this standard to direct the OCS designer and manufacturer toward economizing the construction of supporting structures for OCS and their corresponding footings through consistency and standardization. This standard is intended for use by the following: -- OCS designers to assist in the selection and specification of structure types and sizes, -- Geotechnical engineers to use as a basis for developing footing sizes and anchor bolt configurations, -- Owners and maintainers of new or existing OCS, -- Contractors that construct new OCS, and -- Manufacturers.
