Do fast moving objects in relative motion always observe length contraction regardless of their direction of travel? In every example I find the train or the rod appears to be “moving toward you.” I can’t find any thought experiments describing what happens after you pass the train and it appears to be moving away from you. It seems to me that the length might appear to dilate? But then, wouldn’t the light from the rear of the train reach the relative observer first and the light from the front delayed making it still measure contracted? I don’t know… help?
