Trial trips were made on the Windsor, Brighton, Hastings, and similar roads, and with success. Once the carriage made a trip to Hastings and back, a distance of one hundred and twenty-eight miles, in one day, half the time occupied by the stage coaches. The Mechanic's Magazine said: "We accompanied Hill, about a year ago, in a short run up and down the hills about Blackheath, Bromley, and neighborhood; and we had again the pleasure of accompanying him in a delightful trip, on the Hastings Road, as far as Tunbridge and back. The manner in which his carriage took all the hills, both in the ascent and the descent, proved how completely every difficulty on this head had been surmounted." In the Hill carriage, both the coach and the machinery were erected upon a strong frame mounted upon substantial springs. In the rear were the boiler, furnace, and water tanks, with a place for the engineer and fireman. In front was a coach body with seats for six inside, three on the box, and the conductor in front. The front part of the carriage was also suspended upon springs. The carriage was propelled by a pair of ten-inch cylinders and pistons, horizontally placed beneath the carriage. These acted upon two nine-inch cranks, coupled to the main axle through compensating gear; the two six-foot six-inch diameter driving wheels had the full power of the engines passed through them. The weight of the boiler when empty was two thousand three hundred pounds, and it had a capacity of about sixty gallons of water, while one hundred gallons more were contained in the tanks. The total weight of the carriage, including water, coke, and twelve passengers, was less than four tons. On heavy and rough roads the steam pressure was seventy pounds per square inch, but on good roads only sixty pounds. The average speed was sixteen miles an hour, but on a level twenty miles an hour was reached. As late as 1843, Hill's carriages were running from London to Birmingham, having been in operation four or five years. Smooth in motion, they carried their passengers comfortably, but soon went out of use. GOODMAN Early in the forties a small road locomotive was made by Goodman, of Southwark, London. It was worked by a pair of direct-acting engines, coupled to the crank shaft. A chain pinion on the crank shaft transmitted motion to the main axle through an endless pitch chain working over a chain wheel of larger diameter on the driving shaft. The smoke from the boiler was conducted by a flue placed beneath the carriage. The vehicle had a speed of from ten to twelve miles an hour. NORRGBER A correspondent of The Mechanic's Magazine, of London, wrote in 1843: "Norrgber, of Sweden, a locksmith and an ingenious mechanic, made a steam carriage which ran between Copenhagen and Corsoer, carrying thirty passengers, the engine being of eight horse-power."
