Bogie (locomotive)
A bogie ( ) (or truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Railway Vehicle
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, single or multiple units. A connected series of railway vehicles is a train (this term applied to a locomotive is a common misnomer). In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock in a train. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped to the buyer without much cost or delay. The term contrasts with fixed stock (infrastructu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ride Quality
Ride quality refers to a vehicle's effectiveness in insulating the occupants from undulations in the road surface (e.g., bumps or corrugations). A vehicle with good ride quality provides a comfort for the driver and passengers. Importance Good ride quality provides comfort for the people inside the car, minimises damage to cargo and can reduce driver fatigue on long journeys in uncomfortable vehicles, and also because road disruption can impact the driver's ability to control the vehicle. Suspension design is often a compromise between ride quality and car handling, because cars with firm suspension can result in greater control of body movements and quicker reactions. Similarly, a lower center of gravity is more ideal for handling, but low ground clearance limits suspension travel, requiring stiffer springs. Ambulances have a special need for a high level of ride quality, in order to avoid further injury to the already ill passengers. Technology Early vehicles, like the Ford ...

Midland Railway
The Midland Railway (MR) was a railway company in the United Kingdom from 1844. The Midland was one of the largest railway companies in Britain in the early 20th century, and the largest employer in Derby, where it had its headquarters. It amalgamated with several other railways to create the London, Midland and Scottish Railway at grouping in 1922. The Midland had a large network of lines emanating from Derby, stretching to London St Pancras, Manchester, Carlisle, Birmingham, and the South West. It expanded as much through acquisitions as by building its own lines. It also operated ships from Heysham in Lancashire to Douglas and Belfast. A large amount of the Midland's infrastructure remains in use and visible, such as the Midland main line and the Settle–Carlisle line, and some of its railway hotels still bear the name '' Midland Hotel''. History Origins The Midland Railway originated from 1832 in Leicestershire / Nottinghamshire, with the purpose of serving the needs o ...

Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-2-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer. Overview The wheel arrangement type was common on United States railroads from the 1830s through the 1850s. The first to be built was the ''Experiment'', later named ''Brother Jonathan'', for the Mohawk and Hudson Railroad in 1832. It was built by the West Point Foundry based on a design by John B. Jervis. Having little else to reference, the manufacturers patterned the boiler and valve gear after locomotives built by Robert Stephenson of England. A few examples of Stephenson locomotives were already in operation in America, so engineers did not have to travel too far to get their initial ideas. In England, the was developed around 1840 from the 2-2-2 design of Stephenson's first Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bogie Wagon
A bogie bolster wagon is a British railway term for a wagon designed to carry long thin cargoes such as timber or rails and other steel sections. The sides and ends are minimal and there is no roof. The load is carried longitudinally and borne by three or more bolsters (half baulks of timber) fixed transversely. The load is constrained sideways by movable metal stanchions fitted into the ends of the bolsters, and secured with chains and shackles. Design A bogie bolster has both bogies and bolsters. Bogies are four-wheeled, articulated carriages beneath the main load bed. They allow a long wagon to carry long loads, but still have individually short wheelbases, and so go round tight curves. Bolsters are baulks of timber fixed across the bed. The bed is thus not flat, but most loads such as girders, rails, timber lengths, signal posts etc. are stiff enough that they only need to be supported at intervals, not continuously across a flat planked bed. The space between baulks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
