That is not always correct especially if the rail is laid on top of a heap of ballast and the end is free swinging, or the length is short enough to be moved.It will take a lot more than one person to lift or move a rail!
I've noticed that some very long lengths of old railway track are left in between the tracks instead of being carted away. Why is that? My worry would be that someone could move these tracks and cause a lot of damage.
I rarely see short lengths of rail left in the four-foot. One assumes for precisely this reason.That is not always correct especially if the rail is laid on top of a heap of ballast and the end is free swinging, or the length is short enough to be moved.
