Highland Railway Classes Prior To 1870
The Highland Railway began as the Inverness and Nairn Railway (later the Inverness and Aberdeen Junction Railway), which operated the other lines which became part of the Highland Railway on its formation in 1865. For post-1870 locomotives, see Locomotives of the Highland Railway. Initial locomotive designs William Barclay The first locomotive superintendent was William Barclay, who was a nephew of Alexander Allan. The locomotives supplied initially were classic Allan designs, small 2-2-2s and 2-4-0s, outside cylindered and with external framing and (initially at least) not even a weatherboard to protect the enginemen. It was later decided that a cab was essential to protect them from winter weather. Only four of the Barclay era locomotives, all rebuilt by Jones, were still in service at the time of the Grouping in 1923. Raigmore class The first locomotives were two 2-2-2s were supplied by Hawthorns and Company of Leith in 1855, and a second pair delivered in 1857. Cylinder dim ...

Highland Railway
The Highland Railway (HR) was one of the smaller British railways before the Railways Act 1921, operating north of Perth railway station in Scotland and serving the farthest north of Britain. Based in Inverness, the company was formed by merger in 1865, absorbing over 249 miles (401 km) of line. It continued to expand, reaching Wick and Thurso in the north and Kyle of Lochalsh in the west, eventually serving the counties of Caithness, Sutherland, Ross & Cromarty, Inverness, Perth, Nairn, Moray and Banff. Southward it connected with the Caledonian Railway at Stanley Junction, north of Perth, and eastward with the Great North of Scotland Railway at Boat of Garten, Elgin, Keith and Portessie.Conolly 2004. During the First World War the British Navy's base at Scapa Flow, in the Orkney Islands, was serviced from Scrabster Harbour near Thurso. The Highland Railway provided transport, including a daily ''Jellicoe Express'' passenger special, which ran between London and Th ...

Inverness And Nairn Railway
The Inverness and Nairn Railway was a railway company that operated between the burghs in the company name. It opened its line in 1855 and its passenger business was instantly successful. At first it was not connected to any other line. However it was seen as a first step towards connecting Inverness and Central Scotland, via Aberdeen and when feasible, directly southwards. The Inverness and Aberdeen Junction Railway was building a line connecting Nairn with the Great North of Scotland Railway at Keith, completing a route to Aberdeen and Central Scotland. The I&AJR took over the working of the Nairn company in 1857, and absorbed it in 1861. The Nairn route was therefore on the main route from Inverness to Aberdeen, and from 1863 part of a new direct line to the south from Forres, the Inverness and Perth Junction Railway over a summit at Dava. On the opening of the Inverness and Aviemore Direct Railway route in 1898 most southward trains were diverted away, to that route. Nowad ...

Locomotives Of The Highland Railway
The locomotives of the Highland Railway were used by the Highland Railway to operate its lines in the north of Scotland. The Highland Railway locomotive works was at Lochgorm, Inverness. The works had been built about 1855 by the Inverness and Nairn Railway. The locomotive classes are listed under the names of the railway's Locomotive Superintendents. Locomotives William Barclay 1855–69 During Barclay's incumbency as locomotive superintendent various 2-2-2 and 2-4-0 locomotives were built, along with a solitary 0-4-0T. An 0-4-0ST was also inherited from the Findhorn Railway. Many of Barclay's locomotives would later be rebuilt by Stroudley or Jones - most of the 2-2-2s ended up as 2-4-0s and one became a 2-2-2T, a pair of 2-4-0s became 4-4-0s and the 0-4-0T became an 0-4-2T. Only 4 much rebuilt Barclay locomotives (all 2-4-0s) were still in stock at the time of the Grouping. William Stroudley 1865–69 William Stroudley produced only one new design, an 0-6-0ST of which 3 were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Allan (locomotive Engineer)
Alexander Allan was a Scottish mechanical engineer. He was born at Montrose, Angus, in 1809 and died at Scarborough, Yorkshire on 2 June 1891. Biography Alan was born in Montrose, Angus, Scotland in 1809. He undertook a apprenticeship to Mr. Gibb, a millwright. In 1832 aged about 23 he took a position at Robert Stephenson and Company, Newcastle upon Tyne. By 1834 he had moved to Liverpool and taken up a position with George Forrester and Company who were about to begin building railway locomotives. Allan was works manager for George Forrester and Company until 1840. He was the engineer sent for a year to supervise the maintenance of the three Forrester engines ''Vauxhall'', ''Dublin'' and ''Kingstown'' for the first year of their service at Dublin and Kingstown Railway in 1834. From 1843 to 1853 he was Works Manager at the Crewe Works of the Grand Junction Railway, later London and North Western Railway, under Francis Trevithick. He later claimed the credit for desig ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * Engine displacement Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of t ... References {{Steam engine configurations Engine technology ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Cylinder (locomotive)
The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in iron and later made of steel. The cylinder casting includes other features such as (in the case of the early Rocket locomotive) valve ports and mounting feet. The last big American locomotives incorporated the cylinders as part of huge one-piece steel castings that were the main frame of the locomotive. Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings. The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with. This assessment was known as ...

Adams Bogie
The Adams axle is a form of radial axle for rail locomotives that enable them to negotiate curves more easily. It was invented by William Bridges Adams and patented in 1865. The invention uses axle boxes that slide on an arc in shaped horn blocks, so allowing the axle to slide out to either side. This is similar to the movement of a Bissell truck, but with the notional centre point of the curve being where the pivot of the truck would be. This design, using slide bearings, is more expensive than one employing a shaft, but takes up less space. Trials In 1865 the Society of Engineers, London, made direct comparison between the radial axle, invented by William Bridges Adams, and a bogie design with an india-rubber central bearing invented by William Adams: during trials on the North London Railway the laterally sprung bogie was thought superior to the radial axle, but when William Adams moved from the NLR to the London and South Western Railway he adopted the design of his rival ...

Highland Railway F Class
The Highland Railway F class 4-4-0s were a class of British steam locomotives introduced in 1874. The first 10 were built by Dübs and Company in 1874. A further seven were built in Lochgorm works between 1876 and 1888. Originally they were the first ''Bruce'' class, and later became known as the ''Duke'' class to avoid confusion with the second ''Bruce'' class. As part of Peter Drummond's 1901 classification scheme they became class F. Dimensions They featured 6-feet 3½-inch driving wheels and weighed . The original batch had boilers pressed to , the later batch had slightly smaller boilers but a higher pressure of . Of typical Allan/Jones appearance, they had outside cylinders of . Disposal Withdrawal commenced in 1907, and by 1909 all-but-one of the Dübs-built examples had been withdrawn. Numbers 31A and 74 were retired in 1913, number 71A was broken up in 1915. The remaining five survived until 1923 but none of them acquired a new London, Midland and Scottish Railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highland Railway L Class
The Highland Railway L class, also known as ‘Skye Bogies’ due to their association with the Kyle of Lochalsh Line. They were essentially mixed traffic versions of the earlier ''Duke'' or F class. Construction Nine were built at Lochgorm Works over the period 1882 to 1901. They were never named. Dimensions The cylinders, valve gear and motion were common to the two classes, but they had smaller driving wheels and higher pressure boilers.

Neilson And Company
Neilson and Company was a locomotive manufacturer in Glasgow, Scotland. The company was started in 1836 at McAlpine Street by Walter Neilson and James Mitchell to manufacture marine and stationary engines. In 1837 the firm moved to Hyde Park Street and was known as Kerr, Mitchell and Neilson and, in 1840, Kerr, Neilson and Company, becoming Neilson and Mitchell in 1843. Locomotive building began in 1843 for the local railways. In 1855 production of marine and stationary engines discontinued and the company changed its name again to Neilson and Company. Among those who later became notable in the field were Henry Dübs and Patrick Stirling. By 1861, business had increased to such an extent, that a new works was built at Springburn, also named "Hyde Park Works." In 1864, Henry Dübs set up in business on his own at Queens Park Works, as Dübs and Company, taking a number of key staff with him. James Reid, who had previously worked for Neilson, however, returned and became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharp, Stewart And Company
Sharp, Stewart and Company was a steam locomotive manufacturer, initially located in Manchester, England. The company was formed in 1843 upon the demise of Sharp, Roberts & Co.. It moved to Glasgow, Scotland, in 1888, eventually amalgamating with two other Glaswegian locomotive manufacturers to form the North British Locomotive Company. Early days Iron merchant Thomas Sharp and mechanical engineer Richard Roberts first formed a partnership, Sharp, Roberts & Co. (about which, see also company section in article on Roberts), to manufacture textile machinery and machine tools. They opened the Atlas Works in Manchester in 1828. They had built a few stationary steam engines, and in 1833 built a locomotive, ''Experiment'' for the Liverpool and Manchester Railway. It was a four-wheeled 2-2-0 with vertical cylinders over the leading wheels. After a number of modifications, three similar locomotives (Britannia, Manchester, and ''Hibernia'') were built in 1834 for the Dublin and Kin ...
