A bogie (in some senses called a truck in North American English) is a chassis or framework carrying wheelsets, attached to a vehicle, thus serving as a modular subassembly of wheels and axles.
Catch points and trap points are types of turnout which act as railway safety devices.
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
The Connington South rail crash occurred on 5 March 1967 on the East Coast Main Line near the village of Conington, Huntingdonshire, England.
A railroad crane (North America: crane car or wrecker; UK: breakdown crane) is a type of crane used on a railroad for one of three primary purposes: freight handling in goods yards, permanent way (PW) maintenance, and accident recovery work.
Crashworthiness is the ability of a structure to protect its occupants during an impact.
A cylinder (from Greek κύλινδρος – kulindros, "roller, tumbler"), has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes.
A derail or derailer is a device used to prevent fouling (blocking or compromising) of a rail track (or collision with anything present on the track, such as a person, a train or a fallen branch) by unauthorized movements of trains or unattended rolling stock.
The Eschede derailment occurred on 3 June 1998, near the village of Eschede in the Celle district of Lower Saxony, Germany, when a high-speed train derailed and crashed into a road bridge.
Estray, in law, is any domestic animal found wandering at large or lost, particularly if the owner is unknown.
In materials science, fatigue is the weakening of a material caused by repeatedly applied loads.
Fishplate on the Bluebell Railway In rail terminology, a fishplate, splice bar or joint bar is a metal bar that is bolted to the ends of two rails to join them together in a track.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials.
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
In rail transport use, guard rails or check rails are placed parallel to regular running rail along areas of restricted clearance, such as a bridge, trestle, or tunnel.
In classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x: where k is a positive constant.
The Hatfield rail crash was a railway accident on 17 October 2000, at Hatfield, Hertfordshire, UK.
On 5 November 1967, a busy Sunday evening train service from to was derailed near the Hither Green maintenance depot in London, between and railway stations.
Human error has been cited as a primary cause contributing factor in disasters and accidents in industries as diverse as nuclear power (e.g., the Three Mile Island accident), aviation (see pilot error), space exploration (e.g., the Space Shuttle Challenger Disaster and Space Shuttle Columbia disaster), and medicine (see medical error).
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium.
Hydrogen embrittlement is the process by which hydride-forming metals such as titanium, vanadium, zirconium, tantalum, and niobium become brittle and fracture due to the introduction and subsequent diffusion of hydrogen into the metal.
A level crossing is an intersection where a railway line crosses a road or path at the same level, as opposed to the railway line crossing over or under using a bridge or tunnel.
This is the list of rail accident lists.
The Nuneaton rail crash was a train crash that occurred on 6 June 1975, on the West Coast Main Line just south of Nuneaton railway station in Warwickshire, England.
The Polmont rail accident, also known as the Polmont rail disaster, occurred on 30 July 1984 to the west of Polmont, near Falkirk in Scotland, when a westbound push-pull express train travelling from Edinburgh to Glasgow struck a cow which had gained access to the track through a damaged fence from a field near Polmont railway station.
In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies.
In the Salisbury rail crash of 1 July 1906, a LSWR boat train from Plymouth's Friary railway station to London Waterloo station failed to navigate a very sharp curve at the eastern end of Salisbury railway station.
Shearing forces are unaligned forces pushing one part of a body in one specific direction, and another part of the body in the opposite direction.
The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade.
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.
A train is a form of transport consisting of a series of connected vehicles that generally runs along a rail track to transport cargo or passengers.
A train wreck or train crash is a type of disaster involving one or more trains.
A tram accident is any accident involving a tram.
A wheelset is the wheel - axle assembly of a railroad car.
On May 12, 2015, an Amtrak Northeast Regional train from Washington, D.C. bound for New York City derailed and wrecked on the Northeast Corridor in the Port Richmond neighborhood of Philadelphia, Pennsylvania.
