[quote=DustyRoads;676836]For what it's worth. Train engineers (my second choice), have a high rate of cancer. They claim it is from the electric field created by the electric generator that powers the train. A train engine works by using a diesel engine that turns an electric generator to create electrons to run the train. It works this way because a transmission for a diesel engine that size would be to heavy. I've been wondering if hybrid cars could end up having the same problem.[/quo

I would have thought it would more likely be the diesal fumes and all the heavy metals covering the train from the brake dust, road bed, etc.etc. you encounter.
