HOW TO SUBSCRIBE
In the interest of public safety, transit system operators have an obligation to cooperate willingly with utility operators in the mitigation of stray current created by transit operations and assist the utility corrosion engineer promptly in mitigating the adverse effects of these stray currents when these effects are properly demonstrated. Generally, all parties are represented on local corrosion control coordinating committees (see the sections titled "New Transit Systems" and "New Utility Systems") and fully cooperate with each other in sharing information about the operation of their respective systems.
Transit operators are normally aware of the technical and economic corrosion control requirements of the utilities and other owners and the laws and regulations under which they must operate. Likewise, utility operators, accustomed to controlling corrosion from older transit systems with drainage bonds, recognize the advances that have been made in stray current control through the improved design and maintenance of the modern rail system. Installation of bonds to modern rail systems negates the benefits of corrosion mitigation measures designed into the rail systems.
If a significant stray current problem develops, the utility and transit engineers typically work together to attempt to mitigate the problem. To protect their own and neighboring structures, rail operators have an obligation to maintain the rail system in such a manner that does not compromise the built-in stray current control. In this report, utility operator refers to the owner or operator of any underground utility structure.
