Train tracks symbolize a desire for change or the imminent sense of danger that upcoming change portends.
If the train represents change itself, then the tracks connect to the possibility of shift and change that could be occurring but at present is not yet happening. Train tracks have a measure of danger connected to them because a train could come along at any moment, putting you in peril. In this way, a dream that takes place on train tracks could be pointing to the possibility that some dramatic change is on its way and, when it arrives, has the potential for causing fear or destruction.
The tracks that carry a train indicate all the places a train might go. One interpretation relates to the potential for movement and travel. There is a very powerful association with train tracks as a dividing line between classes, as in the “other side of the tracks.” Which side of the tracks are you on in your dream?
