For an description and operation of the two Visual Basic programs select: VB Train operation.htm
In order to calculate what the observer sees the program handles both the front and the back of the train in the same way.
For both it calculates a virtual position, that means the position where the observer thinks/assumes that each the front and the back of the train is.
For virtual position see also virtual position .
The angle between the two virtual positions shows what we see.
The program shows length contraction in a visible sense, not in a physical sense. This implies that Lorentz Transformation i.e. l as a function of l0 is not required.
