There is a train(think of having only two boggie for a claer visualization ) in which two rod which are attached to the front and rear end of the train(say, the length between these rod is the length of the train). These are lowered by a single lever to touch the ground. These rods are at different length from the body of the train, so that when lowered it will touched the ground at different distance from the track of the train, drawing two lines along the track. The distance between these two starting lines will be the same as that of the length between the rod or to say the length of the train at normal speed. As the train approaches say .8c speed, the lever is lowered to touch the ground. Would the length between the two starting lines drawn along the track, would actually contract, which would be a direct observation of the lorentz length contraction? Thanks.
