The picture claims that the new GE train is the cleanest train that they have built. The reason for this is the fact that it is running by birds and wild and they are unarmed and happy. The qualifier is that the ad says "cleanest ever made" not the cleanest. The warrant for this is that the wildlife would not be around harmful things, therefore the train is clean. There is not much evidence to back this in the picture except for the common knowledge that animals do not stay by pollution.
