A plateway is an early kind of railway , tramway or wagonway , where the rails are made from cast iron . They were mainly used for about 50 years up to 1830, though some continued later.
58-419: Plateways consisted of L-shaped rails, where the flange on the rail guides the wheels, in contrast to edgeways , where flanges on the wheels guide them along the track. Plateways were originally horsedrawn but, later on, cable haulage and small locomotives were sometimes used. The plates of the plateway were made of cast iron , often fabricated by the ironworks that were their users. On most lines, that system
116-413: A crossing loop , crossing place , refuge loop or, colloquially, a hole ) is a place on a single line railway or tramway , often located at or near a station , where trains or trams travelling in opposite directions can pass each other. Trains / trams going in the same direction can also overtake, provided that the signalling arrangement allows it. A passing loop is double-ended and connected to
174-607: A line between Nanpantan and Loughborough , Leicestershire , William Jessop used edge rails cast in 3-foot (0.9 m) lengths, with "fish-bellying" to give greater strength along the length of the rail. However, after he became a partner in Benjamin Outram and Company (Butterley Iron Works) he designed the Surrey Iron Railway and the Kilmarnock and Troon Railway as plateways, though between these (in 1803) he designed
232-487: A passing loop cannot be built. An extra parallel siding is often built at stations on refuge sidings so that two stopping trains can pass, and an extended catch point opposite the refuge siding may be added so as not to interfere with passing trains. If a crossing loop is several times the length of the trains using it, and is suitably signalled, then trains proceeding in opposite directions can pass (cross) each other without having to stop or even slow down. This greatly reduces
290-408: A radio system to set the points from a distance. The design of crossing loops may have to be modified where there are severe gradients that make it difficult for a train to restart from a stationary position, or where the terrain is unsuitable for a normal loop. A crossing loop on steep gradient may have catch points on the downhill end to reduce the impact of runaways. Since central operation of
348-583: A railway, ran a high-pressure steam locomotive with smooth wheels on an 'L' section plateway near Merthyr Tydfil , but it was 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. There was general doubt at the time that smooth wheels could obtain traction on smooth rails. This resulted in proposals using rack or other drive mechanisms. Mr Blenkinsop of Middleton Colliery patented
406-619: A result, in 1767, they began to make cast iron rails. These were probably 6 ft (1.829 m) long, with four projecting ears or lugs 3 in (75 mm) by 3 + 3 ⁄ 4 in (95 mm) to enable them to be fixed to the sleepers . The rails were 3 + 3 ⁄ 4 in (95 mm) wide and 1 + 1 ⁄ 4 in (30 mm) thick. Later, descriptions also refer to rails 3 ft (914 mm) long and only 2 in (50 mm) wide. A later system involved L-shaped iron rails or plates , each 3 ft (914 mm) long and 4 in (102 mm) wide, having on
464-616: A vertical pin on the truck fitting into the gap between the planks to keep it going the right way. The miners called the wagons Hunde ("dogs") from the noise they made on the tracks. Around 1568, German miners working in the Mines Royal near Keswick used such a system. Archaeological work at the Mines Royal site at Caldbeck in the English Lake District confirmed the use of " hunds ". In 1604, Huntingdon Beaumont completed
522-452: A wagonway to a fully steam-powered railway was gradual. Railways up to the 1830s that were steam-powered often made runs with horses when the steam locomotives were unavailable. Even in the steam age, it was 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 take shortcuts from one siding to another. At Hamley Bridge tenders were called for
580-709: A wagonway was proposed to 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. In 1825 he built the locomotive Locomotion for the Stockton and Darlington Railway in England's northeast, which became the world's first public steam railway in 1825, via both horse power and steam power on different runs. Stationary steam engines for mining were generally available around
638-490: Is common in Russia and post-Soviet states. A disadvantage of the platform and through arrangement is the speed limits through the turnouts at each end. In the example layout shown, trains take the left-hand track in their direction of running. Low-speed turnouts restrict the speed in one direction. Two platform faces are needed, and they can be provided either at a single island platform or two side platforms (as shown). Overtaking
SECTION 10
#1733084521251696-453: Is not normally possible at this kind of up-and-down loop as some of the necessary signals are absent. Crossing loops using up-and-down working are very common in British practice. For one thing, fewer signals are required if the tracks in the station are signaled for one direction only; also, there is less likelihood of a collision caused by signalling a train onto the track reserved for trains in
754-422: Is usually located on the main line. If passenger trains are relatively few in number, and the likelihood of two passenger trains crossing each other low, the platform on the loop line may be omitted. If the passenger train from one direction always arrives first, the platform on the loop line may also be omitted by extending the platform past the loop in that direction. The through road has straight track, while
812-593: The Aire & Calder Navigation , running from Wakefield to Outwood , a distance of approximately 3 miles (4.8 km). Edge-rails (with a side rack) were 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 continued to exist until
870-588: The Ruabon Brook Tramway as using edge-rail. An alternative design, with the flange on the outside designed to be additionally used with flanged wheels, was unsuccessfully trialled on the Monmouthshire Canal Company's line shortly before its reconstruction as a modern railway. That idea was taken up in 1861 by the Toronto streetcar system . Horsecars ran on the upper, outer part as edgerail, with
928-632: The Surrey Iron Railway , the Derby Canal Railway , the Kilmarnock and Troon Railway , the Portreath Tramroad in Cornwall, and lines at Coalbrookdale , Shropshire . The plates of a plateway generally rested on stone blocks or sleepers , which served to spread the load over the ground, and to maintain the gauge (the distance between the rails or plates). The plates were usually made from cast iron and had differing cross sections , depending on
986-602: The Surrey Iron Railway , the Kilmarnock and Troon Railway , the Monmouthshire Railway and Canal Company tramroads, and the Severn and Wye Railway , were wholly or partly double-track. Because they had un-flanged wheels, wagons that ran on plateways could also run on ordinary roads. Plateways tended to get obstructed by loose stones and grit, leading to wear. Edgeways avoid the stone obstruction problem. Stone blocks had an advantage over timber sleepers because they left
1044-708: The Wollaton Wagonway , built to transport coal from the mines at Strelley to Wollaton Lane End, just west of Nottingham , England . Wagonways have been discovered between Broseley and Jackfield in Shropshire from 1605, used by James Clifford to transport coal from his mines in Broseley to the Severn River. It has been suggested that these are somewhat older than that at Wollaton. The Middleton Railway in Leeds , which
1102-445: The lumberjacks moved on to other stands of timber as each area was cleared. At least one such pole road system reportedly extended some 20 miles (32 km). Typically the pole rails were logs of 8 to 12 inches (20 to 30 cm) diameter, laid parallel directly on the ground without cross-ties , and joined end-to-end with lap joints and wooden pegs . Rolling stock typically had wheels either with concave rims that hugged
1160-440: The approaching train. Some loops have the points in and out of the loop operated manually, albeit more recent examples have so-called self-restoring switches that allow trains to exit a loop without needing to change the points. Other forms of remote operation included centralized traffic control , in which a train controller changes points and signals from a remote office; and driver-operated points, which enable train crews to use
1218-571: The available space for crossing loops is usually limited, they do not normally have an overlap (safety margin) between the starting signals and the end of the double line. In Australia, the Australian Rail Track Corporation (ARTC) policy provides for overlaps of about 500 m and 200 m respectively in an effort to avoid derailment or collision. Many crossing loops are designed to operate automatically in an unattended mode. Such loops may be track-circuited with home signals cleared by

#17330845212511276-555: The carts being re-engaged with the flanges once across the roadway. Even older than plateways were wagonways , which used wooden rails. Despite its ancient appearance, the Haytor Granite Tramway , the track with ledges cut in stone blocks to produce a similar effect as tram plates, was contemporary with plateways, being built in 1820. Wagonway#Edgeways Wagonways (also spelt Waggonways ), also known as horse-drawn railways and horse-drawn railroad consisted of
1334-540: The early 19th century. In most parts of England the plate-rail was preferred. Plate-rails were used on the Surrey Iron Railway (SIR), from Wandsworth to West Croydon . The SIR was sanctioned by Parliament in 1801 and finished in 1803. Like the Lake Lock Rail Road , the SIR was available to the public on payment of tolls; previous lines had all been private and reserved exclusively for the use of their owners. Since it
1392-420: The first train to arrive must stop or move very slowly, while the second to arrive may pass at speed. If one train is too long for the loop it must wait for the opposing train to enter the loop before proceeding, taking a few minutes. Ideally, the shorter train should arrive first and leave second. If both trains are too long for the loop, time-consuming "see-sawing" (or "double saw-by") operations are required for
1450-553: 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 , rails were made of wood, were a few inches wide and were fastened end to end, on logs of wood or "sleepers", placed crosswise at intervals of two or three feet. In time, it became common 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
1508-637: The horses, equipment and tracks used for hauling wagons, which preceded steam-powered railways . The terms plateway , tramway , dramway , were used. The advantage of wagonways was that far bigger loads could be transported with the same power. The earliest evidence is of the 6 to 8.5 km (3.7 to 5.3 mi) long Diolkos paved trackway, which transported boats across the Isthmus of Corinth in Greece from around 600 BC. Wheeled vehicles pulled by men and animals ran in grooves in limestone , which provided
1566-544: The inner side an upright ledge or flange, 3 in (76 mm) high at the centre and tapering to 2 in (51 mm) at the ends, for the purpose of keeping the flat wheels on the track. Subsequently, to increase strength, a similar flange might be added below the rail. Wooden sleepers continued to be used—the rails were secured by spikes passing through the extremities—but, circa 1793, stone blocks began to be used, an innovation associated with Benjamin Outram , although he
1624-481: 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 in the West Riding of Yorkshire (now West Yorkshire ) used primarily for coal transport. The railway charged a toll and opened for traffic in 1798, making it the world's oldest public railway. The route started at Lake Lock, Stanley , on
1682-408: The main track at both ends, though a dead end siding known as a refuge siding , which is much less convenient, can be used. A similar arrangement is used on the gauntlet track of cable railways and funiculars , and in passing places on single-track roads . Ideally, the loop should be longer than all trains needing to cross at that point. Unless the loop is of sufficient length to be dynamic ,
1740-402: The manufacturer. They were often very short, typically about 3 feet (0.9 m) long, able to stretch only from one block to the next. The L-section plateway was introduced for underground use in about 1787, by John Curr of Sheffield Park Colliery. Joseph Butler , of Wingerworth near Chesterfield , constructed a line using similarly flanged plates in 1788. A leading advocate of plate rails
1798-525: The middle of the 18th century. Wagonways and steam-powered railways had steep uphill sections and 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
Plateway - Misplaced Pages Continue
1856-409: The middle of the track unhindered for the hooves of horses , but timber sleepers had an advantage over stone blocks because they prevented the track from spreading. The gauges of some tramroads increased by a couple of inches after decades of horses passing up the middle but, being loose on the axles, the wheels could usually be adjusted slightly with washers. Level crossings could be made truly level,
1914-523: The opposing direction. In France, they often use spring switches and the speed is equally restricted in both directions. The speed restriction in one direction can be eliminated with higher-speed turnouts, but this may require power operation, as the longer and heavier high-speed turnouts may be beyond the capability of manual lever operation. Refuge sidings are used at locations with gradients too steep for heavy freight trains or steam haulage to depart from conventional passing loops, or confined spaces where
1972-587: The patent for an improved method of rolling rails was granted in 1820 to John Birkinshaw , of the Bedlington Ironworks . His rails were wedge-shaped in section, much wider at the top than at the bottom, with the intermediate portion or web thinner still. He recommended that they be made 18 ft (5.49 m) long, suggesting that several might be welded together end to end to form considerable lengths. They were supported on sleepers by chairs at intervals of 3 ft (914 mm), and were fish-bellied between
2030-472: The platform road has low-speed turnouts at either end. A possible advantage of this layout is that trains scheduled to pass straight through the station can do so uninterrupted; they do not have to reduce their speed to pass through the curve. This layout is mostly used at local stations where many passenger trains do not stop. Since there is only one passenger platform, it is not convenient to cross two passenger trains if both stop. This type of passing loop
2088-454: The points and signals from a single signal box is convenient, and since there are practical limits for the distance to these points and signals, crossing loops can have a system-wide effect on train sizes. Line capacity is partly determined by the distance between individual crossing loops. Ideally these should be located at inverse -integer intervals along the track by travel time. The longest section between successive crossing loops will, like
2146-435: The sleepers by two iron spikes, half-round wooden cross sleepers employed on embankments and stone blocks 20 in (508 mm) square by 10 in (254 mm) deep in cuttings. The fish-bellied rails were found to break near the chairs and starting in 1834, they were gradually replaced with parallel rails weighing 50 lb/yd (24.8 kg/m). In 1804, Richard Trevithick , in the first recorded use of steam power on
2204-412: The supply of horses, in part because normal railway staff lacked horse handling skills. Wooden rails continued to be used for temporary railroads into the twentieth century. Some timber harvesting companies in the southeastern United States created pole roads using unmarketable logs, which were effectively free, to create tracks at a cost of between $ 100 and $ 500 per mile. Permanence was not an issue, as
2262-500: The support points. 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 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
2320-533: The term "railway". As of 2024 , very few horse or cable freight railways are operating, notable examples being the cable-hauled St Michael's Mount Tramway and the Reisszug , which has been in continuous operation since around 1900. A few passenger lines continue to operate, including the horse-hauled Douglas Bay Horse Tramway and the cable-hauled San Francisco cable cars . Passing loop A passing loop (UK usage) or passing siding (North America) (also called
2378-461: The time lost by the first train to arrive at the crossing loop for the opposing train to go by. This system is referred to as a dynamic loop. For example, the Windermere branch line will be getting one to permit a 2tph service pattern. Some railways fit catch points at the ends of crossing loops so that if a train overruns the loop, it is derailed rather than collide with an opposing train. Since

2436-532: The top of the pole rails, or un-flanged wheels with separate guide wheels running against the side of each rail. Steam traction engines and some purpose-built locomotives were successfully used for hauling trains of logs. For example, Perdido was built by Adams & Price Locomotive and Machinery Works of Nashville, Tennessee in 1885 for the Wallace, Sanford and Company sawmill at Williams Station, Alabama , where it hauled up to seven cars of 3 or 4 logs each. This
2494-509: The track element, preventing the wagons from leaving the intended route. The Diolkos was in use for over 650 years, until at least the 1st century AD. Paved trackways were later built in Roman Egypt . Such an operation was illustrated in Germany in 1556 by Georgius Agricola (image left) in his work De re metallica . This line used "Hund" carts with unflanged wheels running on wooden planks and
2552-481: The tracks. Sometimes, the plateway company was forbidden to operate its own wagons, so as to prevent a monopoly situation arising. Some plateways, such as the Gloucester and Cheltenham Railway, were single-track, with passing loops at frequent intervals. The single-track sections were arranged so that wagon drivers could see from one loop to the next, and wait for oncoming traffic if necessary. However, others, such as
2610-416: The trains to cross (see Tawa railway station ). On railway systems that use platforms , especially high-level platforms, for passengers to board and disembark from trains, the platforms may be provided on both the main and loop tracks or possibly on only one of them. The main line has straight track, while the loop line has low-speed turnouts at either end. If the station has only one platform, then it
2668-552: The use of cogged wheels in 1811 and in 1812, the Middleton Railway (edgeway, rack rail) successfully used twin cylinder steam locomotives made by Matthew Murray of Holbeck , Leeds . George Stephenson made his first steam locomotive in 1813 (patented 1815) for the Killingworth colliery, and found smooth wheels on smooth rails provided adequate grip. Although he later recounted that they called this locomotive 'My Lord' as it
2726-420: The weakest link in a chain, determine the overall line capacity. Long and short trains can cross at a short loop if the long train arrives second but leaves first. It is best if all crossing loops are longer than the longest train. Two long trains can cross at a short loop using a slow so-called see-saw process, which wastes time. Countries generally have a principle on which side trains shall meet, either on
2784-419: The wheel flanges on the inside. The edge rail formed an outside flange for a broad foot which allowed wagons to pass through the unmade streets. That combination necessitated a unique, broader gauge of 4 ft 10 + 7 ⁄ 8 in ( 1,495 mm ) known as the Toronto gauge . The early plateways were usually operated on a toll basis, with any rolling stock owner able to operate their wagons on
2842-509: The wooden rollers of the wagons and towards the middle of the 18th century, led to the introduction of iron wheels. 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. In 1760, the Coalbrookdale Iron Works began to reinforce their wooden-railed tramway with iron bars, which were found to facilitate passage and diminish expenses. As
2900-516: Was Benjamin Outram , whose first line was from quarries at Crich to Bullbridge Wharf on the Cromford Canal . The early plates were prone to break, so different cross sections were employed, such as one with a second flange underneath. Some lines later introduced chairs to support the plates on the blocks, and wrought iron plates, increasing the length to 6 feet (1.8 m) and, later, 9 feet (2.7 m), spanning several sleeper blocks In 1789, on
2958-399: Was a geared engine (4.5 to 1 gear ratio ), driving four individually-rotating concave-rim wheels on stationary axles via chain drives; powerful but running less than 5 miles per hour (8.0 km/h). Still later, modified semitrailer tractors have been used. As steam power gradually replaced horse power throughout the 19th century, the term "wagonway" became obsolete and was superseded by
SECTION 50
#17330845212513016-570: Was built in 1758 as a wagonway, later became the world's first operational railway (other than funiculars), albeit in an upgraded form. In 1764, the first railway in America was built in Lewiston, New York as a wagonway. Wagonways improved coal transport by allowing one horse to deliver between 10 and 13 long tons (10.2 and 13.2 t ; 11.2 and 14.6 short tons ) of coal per run— an approximate fourfold increase. Wagonways were usually designed to carry
3074-467: Was financed by Lord Ravensworth , it seems that it was known at the time as Blücher . In 1814 William Stewart was engaged by Parkend Coal Co in the Forest of Dean for the construction of a steam locomotive, which when trialled was reported to be successful. Stewart did not receive his expected reward and the two parties parted on bad terms. Stewart was 'obliged to abandon the engine to that Company'. In 1821,
3132-526: Was first used by William Jessop on a line that 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 laying rails with upstanding ledges or flanges on the turnpike . This difficulty was overcome by paving or "causewaying" the road up to
3190-444: 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, the number of joints per mile was reduced. Joints were always the weakest part of the line. Another advance was the substitution of wrought iron for cast iron, though that material did not gain wide adoption until after
3248-399: Was not the originator. This type of rail was known as the plate-rail, tramway-plate or way-plate, names that are preserved in the modern term " platelayer " applied to the workers who lay and maintain the permanent way . The wheels of flangeway wagons were plain, but they could not operate on ordinary roads as the narrow rims would dig into the surface. Another form of rail, the edge rail ,
3306-590: Was replaced by rolled wrought iron (and later steel ) "edge rails" which, along with realignment to increase the radius of curves, converted them into modern railways, better suited to locomotive operation. Plateways were particularly favoured in South Wales and the Forest of Dean , in some cases replacing existing edge rails. Other notable plateways included the Hay Railway , the Gloucester and Cheltenham Railway ,
3364-545: 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, ironworks, 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 soon its superiority
