Now this type is a smart idea. They have using watchmen heaters for years that keep the engine warm. These I guess would be called a smart start system using a small engine to keep the coolant and oil warm. The watchmen heaters are kind of like the blockheaters put on diesel truck. On really cold days it is hard to strat a diesel but if you keep the block warm it starts easier. On locomotives they use water for coolant, on the new engines like the 90 they use antifreeze. The ones with water, if you shut down the engine the water will freeze and cause major damage. I have seen a radiator core that forze and it wasn't pretty. As it turns out the main engine stopped during the night maybe due to a vandal and the water froze. On the side of engines there is a emergency fuel shut off and they think the vandal saw that. From them on all unattended locomotives had to drain the water and shut down properly on this local job. CSX has installed some of the small diesels and I thinks NS is trying out their system. Some of the NS engines have a plaque that tells they have experimental equipment aboard. As to the Battery Green Goat, railroads and railroad people are not used to change, but that doesn't mean we don't. The engine is a good idea it just needs to used to find it limitations and design a better system. But when you got engines that last so long you don't have to run out and buy more, except maybe UP they are impulse buyers, only my girlfriend buys more stuff:)
