The Works were built by Messrs. Peto and Betts, from designs furnished by Joseph Cubitt, Esq., engineer, and finished in the year 1863, (two years ago the erecting shop was enlarged). The name, however, is still retained and the Works are called Long-Hedge Works. These Works are surrounded with a wall ten feet high. There are six gates, but the principal entrance to the Works is at the gate by the time-keeper's office; the other five gates are used for shunting purposes. Within this enclosure no person is allowed to go except on business, and this rule is strictly carried out. There are the boiler-shop, the tender-shop, erecting shop, copper-smiths' shop, fitting-shop, brass-finishers' shop, pattern-makers' shop, smiths' shop, boiler-house with three large boilers, which drive the large stationary engine. The whole of these buildings, which consists of a series of ranges, are substantially built of brick, with walls of immense thickness. On the south side is the stores department. At the east-end of the turnery is the Superintendent's office, clerks' offices, etc. The area between each shop has an intersection of rails communicating with the line. The lower turnery is 250 feet long and 44 wide. It has twenty-five windows on either side; the dimensions of each window is 12 feet by 3, and a third portion of each window can be opened or closed at pleasure for ventilation; also three pairs of double doors of the same height as the windows, and wide enough to admit a truck or carriage. There are lines of rails laid parallel with the building, both on the outside and through the centre. Opposite each of the large doors, both inside and out, are turn tables to connect the shops with any part of the yard. The floor is laid with blocks of wood about five inches square. Around large steam-pipes are laid on either side of the shop to add to the comfort and convenience of the men. The shaft which gives motion to the machinery passes through the centre of the shop and the machinery on each side. Towards one extremity of this range of building is the engine house, in which are two beautifully-finished high and low pressure horizontal engines of one hundred horse power, which drive all the machinery and fan-blasts for smiths. There are three boilers, each thirty feet long, and six feet in diameter, having pressure of forty pounds upon every square inch. The shaft belonging to the stationary engine is forty-seven yards high. In the lower turnery there is a double-headed slot-wheel, three large wheel lathes, and two small wheel lathes; the small are for carriage wheels. There are also three fifteen-inch lathes, two crank lathes for turning crank axles, two twelve-inch lathes, two large boring machines--one of these is a radial machine for boring tube plates; one boring machine for cylinders, also one large planing machine for the same purpose, and one hydraulic press for taking off axles. On the same basement with the turnery is the Loco. Manager's office.
