Wagonways (or Waggonways) consisted of the horses, equipment and tracks used for hauling wagons, which preceded steam powered railways. The terms "plateway", "tramway" and in someplaces, "dramway" are also found.
The idea of using "tracked" roads is at least 2000 years old; quarries in Ancient Greece, Malta and the Roman Empire used cut stone tracks to haul loads pulled by animals, as the Greek Diolkos did for transporting ships overland.
Early modern developments
Around 1568, German miners working in the Mines Royal near Keswick had knowledge of tub railways, as archaeological work at the Mines Royal site at Caldbeck in the English Lake District has now confirmed the use of "hunds", as track fragments have been found. The wooden tubs, known as "hunds" ("dog" in German) ran on two wide boards or rails and were used to move ore within the mines. These hunds used a guide pin system, utilising the slot between the two board rails to keep them on course.
The first true railways, using a flange to keep the wheel on a rail, were developed in the early 17th century. In 1604, Huntingdon Beaumont completed the Wollaton Wagonway, built to transport coal from the mines at Strelley to Wollaton Lane End, just west of Nottingham, England. Wagonways have been proven to exist in Broseley and in Shropshire from 1605, but it has recently been suggested that used by James Clifford to transport coal from his mines in Broseley to the river Severn was somewhat older than that at Wollaton.
Wagonways improved coal transport by allowing one horse to deliver between 10 to 13 long tons (10.2 to 13.2 t; 11.2 to 14.6 short tons) of coal per run— an approximate fourfold increase. Wagonways were usually designed to carry the fully loaded wagons downhill to a canal or boat dock and then return the empty wagons back to the mine.
Until the beginning of the Industrial Revolution, the rails were made of wood, were a few inches wide and were fastened down, end to end, on logs of wood or "sleepers", placed crosswise at intervals of two or three feet. In time, it became a common practice to cover them with a thin flat sheathing or "plating" of iron, in order to add to their life and reduce friction. This caused more wear on the wooden rollers of the wagons and towards the middle of the 18th century, led to the introduction of iron wheels, the use of which is recorded on a wooden railway near Bath in 1734. However, the iron sheathing was not strong enough to resist buckling under the passage of the loaded wagons, so rails made wholly of iron were invented.
The first iron rails
In 1767, the Coalbrookdale Iron Works began to cast iron rails. These were probably 6 ft (1,830 mm) long, with four projecting ears or lugs 3 in (75 mm) by 3 in (95 mm) to enable them to be fixed to the sleepers. The rails were 3⁄43 in (95 mm) wide and 3⁄41 in (30 mm) thick. Later, descriptions also refer to rails 3 ft (915 mm) long and only 2 in (50 mm) wide. 1⁄4
A later system involved "L" shaped iron rails or plates, each 3 ft (915 mm) long and 4 in (100 mm) wide, having on the inner side an upright ledge or flange, 3 in (75 mm) high at the centre and tapering to a height of 2 in (50 mm) at the ends, for the purpose of keeping the flat wheels on the track.
Subsequently, to increase the strength, a similar flange might be added below the rail. Wooden sleepers continued to be used— the rails being secured by spikes passing through the extremities— but, circa 1793, stone blocks also began to be used, an innovation associated with the name of Benjamin Outram, who, however, was not the first to make it. This type of rail was known as the plate-rail, tramway-plate or way-plate, names which are preserved in the modern term "platelayer" applied to the men who lay and maintain the permanent way of a railway.
The wheels of a flangeway were plain, and could theoretically operate on ordinary roads. This was probably not often done as the narrow wheels would dig into the surface.
Edgeway, edge rails
Another form of rail, the edge rail, was first used by William Jessop on a line which was opened as part of the Charnwood Forest Canal between Loughborough and Nanpantan in Leicestershire in 1789. This line was originally designed as a plateway on the Outram system, but objections were raised to rails with upstanding ledges or flanges being laid on the turnpike road, this difficulty was overcome by paving, or "causewaying", the road up to the level of the top of the flanges. In 1790, Jessop and his partner Outram began to manufacture edge-rails. Another example of the edge rail application was the Lake Lock Rail Road used primarily for coal transport. This was a public railway (charging a toll) and opened for traffic in 1798. The route started at Lake Lock, Stanley, on the Aire & Calder Navigation, near Wakefield, and ran to Outwood, a distance of approximately 3 miles (4.8 km). Edge-rails (with a side rack) were also used on the nearby Middleton - Leeds rack Railway (a length of this rail is on display in Leeds City Museum).
The wheels of an edgeway have flanges, like modern railways and tramways. Causewaying is also done on modern level crossings and tramways.
These two systems of constructing iron railways, the "L" plate-rail and the smooth edge-rail, continued to exist side by side until well on into the 19th century. In most parts of England the plate-rail was preferred, and it was used on the Surrey Iron Railway, from Wandsworth to West Croydon, which, sanctioned by parliament in 1801, was finished in 1803, and like the Lake Lock Rail Road was available to the public on payment of tolls, previous lines having all been private and reserved exclusively for the use of their owners. Since it was used by individual operators, vehicles would vary greatly in wheel spacing (gauge) and the plate rail coped better.
In South Wales again, where in 1811 the railways were connected with canals, collieries, iron and copper works, and had a total length of nearly 150 miles (241 km), the plateway was almost universal. But in the North of England and in Scotland the edge-rail was held in greater favor, and by the third decade of the century its superiority was generally established. Wheels tended to bind against the flange of the plate rail and mud and stones would build up.
The manufacture of the rails themselves was gradually improved. By making them in longer lengths, a reduction was effected in the number of joints, always the weakest part of the line; and another advance consisted in the substitution of wrought iron for cast iron, though that material did not gain wide adoption until after the patent for an improved method of rolling rails granted in 1820 to John Birkinshaw, of the Bedlington Ironworks, Northumberland. His rails were wedge-shaped in section, much wider at the top than at the bottom, with the intermediate portion or web thinner still, and he recommended that they should be made 18 ft (5.49 m) long, even suggesting that several of them might be welded together end to end to form considerable lengths. They were supported on sleepers by chairs at intervals of 3 ft (915 mm), and were fish-bellied between the points of support. As used by George Stephenson on the Stockton & Darlington and Canterbury & Whitstable lines they weighed 28 lb/yd (13.9 kg/m). On the Liverpool and Manchester Railway they were usually 12 or 15 ft (3.66 or 4.57 m) long and weighed 35 lb/yd (17.4 kg/m), and they were fastened by iron wedges to chairs weighing 15 or 17 lb (6.8 or 7.7 kg) each. The chairs were in turn fixed to the sleepers by two iron spikes, half-round wooden cross sleepers being employed on embankments and stone blocks 20 in (508 mm) square by 10 in (254 mm) deep in cuttings. The fishbellied rails, however, were found to break near the chairs and from 1834, they began to be replaced with parallel rails weighing 50 lb/yd (24.8 kg/m).
The wagonway had come into considerable use in connection with collieries and quarries before it was realized that for the carriage of general merchandise it might prove a serious competitor to the canals, of which a large distance had been constructed in Great Britain during that period. In the article on "Railways" in the Supplement to the Encyclopædia Britannica, published in 1824, it is said: "It will appear that this species of inland carriage is principally applicable where trade is considerable and the length of conveyance short; and is chiefly useful, therefore, in transporting the mineral produce of the kingdom from the mines to the nearest land or water communication, whether sea, river or canal. Attempts have been made to bring it into more general use, but without success; and it is only in particular circumstances that navigation, with the aid either of locks or inclined planes to surmount the elevations, will not present a more convenient medium for an extended trade." It must be remembered, however, that at this time the railways were nearly all worked by horse-traction, and that the use of steam had made but little progress.
In 1804, Richard Trevithick, in the first recorded use of self-propelled steam power on a railway, ran a high-pressure steam locomotive with smooth wheels, on an 'L' section plateway near Merthyr Tydfil, but it was found more expensive than horses. He made three trips from the iron mines at Penydarren to the Merthyr-Cardiff Canal and each time broke the rails that were designed for horse wagon loads. In 1812, the Middleton Railway (edgeway, rack rail) successfully used twin cylinder steam locomotives made by Matthew Murray of Holbeck, Leeds. In 1821, a wagonway was proposed that would connect the mines at West Durham, Darlington and the River Tees at Stockton, George Stephenson successfully argued that horse drawn wagonways were obsolete and a steam powered railway could carry 50 times as much coal. Shortly after the completion of the Stockton and Darlington railway in 1825, coal transport prices began falling rapidly.
Stationary steam engines for mining were generally available around the middle of the 18th century, wagonways and steam powered railways that had steep uphill sections would employ a cable powered by a stationary steam engine to work the inclined sections. British troops in Lewiston, New York used a cable wagonway to move supplies to bases before the American Revolutionary War. The Stockton and Darlington had two inclined sections powered by cable.
The transition from a wagonway to a fully steam powered railway was a gradual evolution. Railways up to 1835 that were steam powered often made runs with horses when the steam locomotive were unavailable. The Baltimore and Ohio Railroad, which initially opened in 1830 with 13 miles (21 km) of track, was horse powered. Railroads powered by stationary engines and cables (San Francisco cable cars) and horse-drawn trams (Isle of Man, Douglas Bay Horse Tramway) are still in use today.
Even in the steam age, it has been convenient to use horses in station yards to shunt wagons from one place to another. Horses do not need lengthy times to raise steam in the boiler, and can also take short cuts from one siding to another. At Hamley Bridge tenders were called for the supply of horses, in part because normal railway staff lacked horse handling skills.
A number of short and isolated lines were originally operated by horse, unless connected to the main system and converted to locomotive operation. These include:
