chamber. An application of this principle is suggested for all trains in the following manner : — Each train to carry, as already described, a vehicle at the front and at the rear end. The said vehicle is to have the shape and form of a van, but to be strongly built and to contain water, lying on the top of which would be coverings of a collapsible nature ready to fall with the decrease of water, but not to rise with any pressure of the same unless it be when the van is getting re-filled at a station water tank. vSuch vans could permit of a certain proportion of their contents being available for the engines, and in this manner the abnormally large tenders on express trains at present in use rould be dispensed with in favour of a smaller type. The vans being of a collapsible and telescopic order, both in body and frame underneath, would, in the event cf a collision, help to save the fearful effects, as such an arrangement would permit the water to make an excellent cushion. It, of course, would pour out through the valves provided for the purpose under the hecvy weight of a colliding train, but it is hoped that with such a van on each of the trains involved, the safety of the passengers would be assured."
