Caledonian Railway 72 Class
The Caledonian Railway 72 Class was a class of 4-4-0 steam locomotives introduced by William Pickersgill for the Caledonian Railway (CR) in 1920. Thirty-two locomotives were built and all survived to be taken over by the London, Midland and Scottish Railway (LMS) in 1923 and by British Railways (BR) in 1948. The earlier 113 Class (introduced in 1916), of which 16 were produced, were similar but slightly smaller. These were the Caledonian's last express passenger locomotives, and technically, the last of the Dunalastair series, and were unofficially dubbed, Dunalastair V. Numbering The two classes together totalled 48 locomotives. No. 54481 was scrapped after an accident at Gollafield Junction in 1953, the remainder were withdrawn between 1959 and 1962. Dimensions Figures given in this section are from BR Database. Figures given by Rail UK are slightly different. 72 Class See box, top right. 113 Class See table below.

Dingwall Railway Station
Dingwall railway station serves Dingwall, Scotland. It is located just south of the junction of the Far North Line and the Kyle of Lochalsh Line, and is managed and served by ScotRail. The station is from Inverness, and is the zero point for the Kyle of Lochalsh Line. It is sited after Conon Bridge heading northbound, with the next station being either Garve or Alness. History The station was built by the Inverness and Ross-shire Railway (I&RR) and opened on 11 June 1862 when the company's line was opened from to Dingwall. The extension to Invergordon came on 23 March 1863. The I&RR was consolidated with the Inverness and Aberdeen Junction Railway on 30 June 1862. The operating name became the Highland Railway (HR) on 29 June 1865. Under Highland Railway ownership the current station buildings were erected in 1886 by architect Murdoch Paterson. The HR became a constituent of the London Midland and Scottish Railway (LMSR) in 1923. The main passenger services through ...

Fire-tube Boiler
A fire-tube boiler is a type of boiler invented in 1828 by Marc Seguin, in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or " haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical ...

Caledonian Railway Locomotives
Caledonian is a geographical term used to refer to places, species, or items in or from Scotland, or particularly the Scottish Highlands.

Locomotives Of The London, Midland And Scottish Railway
The London, Midland and Scottish Railway had the largest stock of steam locomotives of any of the 'Big Four' Grouping, i.e. pre-Nationalisation railway companies in the UK. Despite early troubles arising from factions within the new company, the LMS went on to build some very successful designs; many lasted until the end of steam traction on British Railways in 1968. For an explanation of numbering and classification, see British Rail locomotive and multiple unit numbering and classification. Various locomotives were inherited from pre-grouping companies. Those from the smaller railways, and hence non-standard, were withdrawn quite early, while ex-Midland, LNWR and L&YR types persisted. The Midland had long had a 'small engine policy', preferring small engines hauling frequent, fairly short trains, and employing a second locomotive (double-heading) where necessary. However, this practice, while emininently suitable for the route from Sheffield, Derby and Nottingham to London was n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotives Of The Caledonian Railway
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Tractive Effort
In railway engineering, the term tractive effort describes the pulling or pushing capability of a locomotive. The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one or more wheels in frictional contact with a railroad track. Defining tractive effort The term ''tractive effort'' is often qualified as ''starting tractive effort'', ''continuous tractive effort'' and ''maximum tractive effort''. These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction () between the driving wheels and supporting surface, and the weight applied to the driving wheels (). The product of and is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Classification
A number of different numbering and classification schemes were used for the locomotives owned by the London, Midland and Scottish Railway (LMS) and its constituent companies. The LMS, formed on 1 January 1923 from many smaller companies included the Caledonian Railway (CR), Furness Railway (FR), Glasgow and South Western Railway (GSWR), Highland Railway (HR), Lancashire and Yorkshire Railway (LYR), London and North Western Railway (LNWR), Maryport and Carlisle Railway (MCR), Midland Railway (MR), North London Railway (NLR) and North Staffordshire Railway (NSR) as well as the minor Cleator and Workington Junction Railway (C&WJR), Glasgow and Paisley Joint Railway (G&PJR), Knott End Railway (KER), Stratford-upon-Avon and Midland Junction Railway (S&MJR), and Wirral Railway (WR) and from October 1936 the Somerset and Dorset Joint Railway (S&DJR) For information about individual classes and locomotives, see Locomotives of the London, Midland and Scottish Railway.

Valve Gear
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion". Purpose In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke) while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder (expansive working). The point at which steam stops being admitted to the cylinder is known as the '' cutoff'', and the optimal posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
