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.

Crane (rail)

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.

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.

Eschede derailment

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.

Guard rails (rail)

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.

Harmonic oscillator

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.

Human error

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).

Hydrogen embrittlement

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.
