This actuality from 1905 looks to be fairly antiquated for the year it is listed as entering the catalogue. Cinematically, it is a single take, longer than it would have been half a decade earlier, but showing no advancement in technique. Motion proceeds, as always, from the upper mid-right towards the lower left. There's no motion or action outside of that; there's water, and then there's not, no sense of how the water is brought into the train.
