This report analyses the coolant management practices and procedures implemented at rail maintenance facilities to maintain the quality of coolants used in the GE Evolution and Dash 9 Series locomotives. Key motivations for the work conducted in this analysis include the identification of sediment observed in locomotive coolant samples and investigation into radiator core failure.

In the conduct of the analysis experimental data validated the implementation of a method to determine the nitrite based corrosion inhibitor concentration through measurement of the electrical conductivity. Further experimentation confirmed that research identifying a minimum concentration of nitrite corrosion inhibitor of 500 ppm as adequate for effective inhibition could be applied as a reference minimum concentration for the corrosion inhibitor package to inhibit corrosion over the variety of metals that comprise the locomotive cooling system.

Investigation into conclusions previously made as to the cause of radiator core failure in the locomotive have been determined to be unfounded and more probable causes for the material degradation have been identified. Recommendations have been made to implement a number of changes for the purpose of optimising the coolant management processes.
