This is a poor use of disk space. The footage is often breathtaking, however it is often shot through the glass of the train window, with streeks/reflections visible between the camera and the view. Furthermore there was no attempt to edit the sound as would have been expected, thus the sound of the dispatcher can be heard when the camera was stationed in the engineer's position. Not recommended.
