The fact is, that railway carriers have been content to use rude square boxes on wheels, covered when loaded, if covered at all, with a tarpaulin, without any precautions for draining off the wet, to which it was constantly exposed when out of use,--without "buffers" or other protecting springs, so that the wear and tear of the waggon and its load, from inevitable shocks, was very great. The imperfect protection of a tarpaulin was, and is, a great temptation to pilferage. These sources of expense, in wear and tear of conveyances, loss of tarpaulin coverings, each worth 6 pounds 6s., breakage, pilferage of goods, combine to sum up a formidable discount from the profits of railway carrying, and, in the case of certain goods, lead the owners to prefer the slower transit of a canal boat. Even iron suffers in market value from exposure to the weather; porcelain and glass are liable to perpetual smashes, on waggons without buffers, in spite of the most careful packing; while tea, sugar, cheese, and all untraceable eatables are pilfered to an enormous extent, besides more valuable goods. It was hoped that railway transit would put an end to the dishonesty which was carried on wholesale on the canals; but, where open trucks are used, this expectation has been only partly realised, for the temptation of opportunity has been too strong, for even the superior class of men employed on railways. In order to meet these evils, Mr. Henson, who has the charge of the waggon- building department at Camden, has built and patented a covered waggon with buffers, which unites with great strength, safety, capacity, and smoothness of motion. The scientific manner in which these waggons are framed, gives them strength in proportion to their weight. The buffers with which they are fitted, and the roof, protecting from the weather, render them altogether durable, and therefore economical; while the construction, as will be seen from our vignette, renders pilferage, unless by collusion with the respectable party who overlooks the unloading, almost impossible. A diminution of the cost for repairs of rolling stock (on an average equal to 12 pounds per ann.), and of the cost for compensation to customers for breakage and pilferage, should be a leading object with every sensible railway director. Indeed these losses, with deadweight, and lawyer's bills, are the deadly enemies of railway directors. Further improvements in these waggons have been effected by the use of corrugated iron, which is light and strong at the same time; and the iron waggons have been again improved by employing iron covered with a thin coating of glass, under a new patent, which renders rust impossible and paint unnecessary. The simple contrivance by which the door and moveable roof is locked and unlocked by one motion, is worthy of the notice of practical men. 600 of these lock-up waggons, with springs and buffers, are in use on the London and North Western Railway.
