I have served as a project manager for both rolling stock procurements (“railway cars”) and as a project manager for new and rehabilitated passenger rail stations. In those roles, I was responsible for safety certification of all project elements, including the grounding requirements. Additionally, I was involved with electric traction construction. I have specific experience with the type of rail car in question. I have also reviewed similar accident/safety events internally.

I have hands on experience with traction motors, their gearboxes, and the grounding that goes along with connecting the whole system – through bearing structure, to axle, wheel, ground, etc. I worked in the electrical engineering industry for several years doing this type of work and have a great deal of railroad experience.
