Track (rail transport)

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. It enables trains to move by providing a dependable surface for their wheels to roll. For clarity it is often referred to as railway track (British English and UIC terminology) or railroad track (predominantly in the United States). Tracks where electric trains or electric trams run are equipped with an electrification system such as an overhead electrical power line or an additional electrified rail.

The term permanent way also refers to the track in addition to lineside structures such as fences etc.

Structure

Traditional track structure

Notwithstanding modern technical developments, the overwhelmingly dominant track form worldwide consists of flat-bottom steel rails supported on timber or pre-stressed concrete sleepers, which are themselves laid on crushed stone ballast.

Power!

Power! (known as Critical Mass in Europe) is a computer game developed by Simon Francis in 1985 for the Amstrad CPC, Commodore 64 and ZX Spectrum.

Plot

The player operates a rocket-powered hovercraft whose mission is to destroy an enemy transfer beam that is protected not only by long-distance enemy raiders and mines, but also molecular disorientation that sucks the energy from the player's attack craft.

Gameplay

The player may control the hovercraft in either a normal joystick operational mode or with vectored movement. When the player pushes forward on the joystick, the hovercraft accelerates, and when pulling back on the joystick, speed decreases.

Reception

In 1988, Dragon reviewed Power!, and gave the game 4 out of 5 stars.

PoweredUSB

PoweredUSB, also known as Retail USB, USB PlusPower, and USB +Power, is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter. It is mostly used in point-of-sale equipment, such as receipt printers and barcode readers.

History

PoweredUSB, as a proprietary variant of USB, was developed and proposed by IBM, Berg (now FCI), NCR and Microsoft between 1998 and 1999, with the last revision (0.8g) issued in 2004. The specification is not endorsed by the USB Implementers Forum (USB-IF). IBM, who owns patents to PoweredUSB, charges a licensing fee for its use.

PoweredUSB was licensed by Hewlett-Packard, Cyberdata, Fujitsu, Wincor and others.

Implementation

PoweredUSB uses a more complex connector than standard USB, maintaining the standard USB 1.x/2.0 interface for data communications and adding a second connector for power. Physically, it is essentially two connectors stacked such that the bottom connector accepts a standard USB plug and the top connector takes a power plug.
