K. C. Randall: Is there any provision for lightning protection? Julian C. Smith: It is certainly a rather prominent development to think that the transmission system has provided this equipment for taking care of wrecks. Why did the authors use three single-phase transformers? It would seem that for the purpose a three-phase transformer would be smaller and lighter, and all the purposes served by these transformers could have been accomplished by the three-phase transformer. It would have taken less space and could have been set down through the car, and possibly an oil switch might have been set on top of it.
