Alternating current

Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction.

Auckland

Auckland (Tāmaki Makaurau) is a large metropolitan city in the North Island of New Zealand. It has an urban population of about It is located in the greater Auckland Region, the area governed by Auckland Council, which includes outlying rural areas and the islands of the Hauraki Gulf, and which has a total population of as of It is the most populous city of New Zealand and the fifth largest city in Oceania.

Australian Rail Track Corporation

The Australian Rail Track Corporation (ARTC) is an Australian Government-owned statutory corporation.

Axle

An axle or axletree is a central shaft for a rotating wheel or gear.

See Axle counter and Axle

Bogie

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.

See Axle counter and Bogie

Defect detector

A defect detector is a device used on railroads to detect axle and signal problems in passing trains.

See Axle counter and Defect detector

Direct current

Direct current (DC) is one-directional flow of electric charge.

See Axle counter and Direct current

Distributed acoustic sensing

Rayleigh scattering-based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing.

See Axle counter and Distributed acoustic sensing

Ethernet

Ethernet is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).

See Axle counter and Ethernet

Forth Bridge

The Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, west of central Edinburgh.

See Axle counter and Forth Bridge

High-speed rail

High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks.

See Axle counter and High-speed rail

Higher-speed rail

Higher-speed rail (HrSR), also known as high-performance rail, higher-performance rail, semi-high-speed rail or almost-high-speed rail, is the jargon used to describe inter-city passenger rail services that have top speeds of more than conventional rail but are not high enough to be called high-speed rail services.

See Axle counter and Higher-speed rail

Interlocking

In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings.

See Axle counter and Interlocking

Level crossing

A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or tunnel.

See Axle counter and Level crossing

Lists of rail accidents

This is the list of rail accident lists.

New Zealand

New Zealand (Aotearoa) is an island country in the southwestern Pacific Ocean.

Optical fiber

An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other.

See Axle counter and Optical fiber

Pneumatics

Pneumatics (from Greek πνεῦμα 'wind, breath') is a branch of engineering that makes use of gas or pressurized air.

See Axle counter and Pneumatics

Rail inspection

Rail inspection is the practice of examining rail tracks for flaws that could lead to catastrophic failures.

See Axle counter and Rail inspection

Rail signaller

A signalman or signaller is an employee of a railway transport network who operates the points and signals from a signal box in order to control the movement of trains.

See Axle counter and Rail signaller

Railroad switch

A railroad switch, turnout, or points is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.

See Axle counter and Railroad switch

Railway signalling

Railway signalling, or railroad signaling, is a system used to control the movement of railway traffic.

See Axle counter and Railway signalling

Safety-critical system

A safety-critical system or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes.

See Axle counter and Safety-critical system

Severn Tunnel

The Severn Tunnel (Twnnel Hafren) is a railway tunnel in the United Kingdom, linking South Gloucestershire in the west of England to Monmouthshire in south Wales under the estuary of the River Severn.

See Axle counter and Severn Tunnel

Severn Tunnel rail accident

On 7 December 1991, two trains collided inside the Severn Tunnel, between England and Wales.

See Axle counter and Severn Tunnel rail accident

Signalling block system

Signalling block systems enable the safe and efficient operation of railways by preventing collisions between trains.

See Axle counter and Signalling block system

Track circuit

A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. Axle counter and track circuit are train detection systems.

See Axle counter and Track circuit

Track geometry

Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track.

See Axle counter and Track geometry

Transmission system

In telecommunications, a transmission system is a system that transmits a signal from one place to another.

See Axle counter and Transmission system

Treadle (railway)

In railway signalling, a treadle is a mechanical or electrical device that detects that a train wheel has passed a particular location. Axle counter and treadle (railway) are train detection systems.

See Axle counter and Treadle (railway)

Tunnel

A tunnel is an underground or undersea passageway.

See Axle counter and Tunnel

8-bit computing

In computer architecture, 8-bit integers or other data units are those that are 8 bits wide (1 octet).
