UNDER the heading of “A New Development of Economical Railway Haulage,” the Times of February 13 tells us that “we are on the eve of a mechanical revolution such as has never been seen since the introduction of steam,” and enters in a general way into a statement of results said to have been obtained from an old Great Northern locomotive fitted with a new type of valve-gear, the use of which is said to reduce the consumption of coal nearly 50 per cent, and increase the hauling capacity of the engine considerably, when compared with a sister engine fitted with the ordinary gear and doing similar work.
