Sydney Trains C Set
The C sets were a class of electric multiple units that operated on Sydney's suburban rail network from 1986 up until 2021. Built by A Goninan & Co between 1986 and 1987, they were introduced into service by the State Rail Authority, before later being operated under CityRail and Sydney Trains. A total of 56 carriages were built, with the last sets being withdrawn from service in February 2021, having been gradually replaced by A & B set trains. Design & construction The C sets were a follow-on from the K sets. They were built as an interim measure due to delays with the Tangara program. They were also used to train and familiarise staff with the new (at the time) chopper technology. The C sets were the first Sydney suburban trains to be fitted with chopper control, which gives the train smoother acceleration. Gate turn-off thyristors (GTO) were used to control power to the traction motors, hence allowing for smoother acceleration."New Suburban Train" ''Railway Digest'' S ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thyristor
A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large (breakdown voltage). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more complex devices that incorporate at least four layers of alternating N-type and P-type substrate. The first thyristor devices were ...

Pulse-width Modulation
Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of reducing the output of solar panels to that which can be utilized by a battery. PWM is particularly suited for running inertial loads such as motors, which are not as easily affected by this discrete switching, because their inertia causes them to react slowly. The PWM switching frequency has to be high enough not to affect the load, which is to say that the resultant waveform perceived by the load must be as smooth as possible. The rate (or frequency) ...

Sydney Trains T Set
The T sets, also referred to as the Tangara trains, are a class of electric multiple units that currently operate on the Sydney Trains network. Built by A Goninan & Co, the sets entered service between 1988 and 1995, initially under the State Rail Authority and later CityRail. The T sets were built as "third-generation" trains for Sydney's rail fleet, coinciding with the final withdrawals of the "Red Rattler" sets from service in the late 1980s and early 1990s. The Tangaras were initially built as two classes; the long-distance G sets and the suburban T sets, before being merged after successive refurbishments. Design The Tangara is a double-deck four-car set, with the two outer cars being driving control trailers (carrying a D prefix) that are fitted with one pantograph each and the middle two cars being non-control motor cars (carrying an N prefix). All sets are equipped with chopper control. Unlike most other Sydney Trains rolling stock, the seats on the suburban T set ...

Sydney Trains K Set
The Sydney Trains K sets are a class of electric multiple units that currently operate on the Sydney Trains network. Built by A Goninan & Co, the K sets first entered service in 1981 operating under the State Rail Authority, and later CityRail. The carriages are of stainless steel, double deck construction and share much of their design with the older S sets. All of the 40 K sets originally built (160 carriages) remain in service and are currently the oldest in the Sydney Trains fleet. Design & construction The K sets were the first New South Wales suburban trains to be air conditioned and have headlights. Two orders were placed for the K sets with all manufactured between 1981 and 1985 by A Goninan & Co in Broadmeadow: *Order 1 *Order 2 The first order featured low mounted upper deck windows, cream and brown interiors, and unpainted fronts.
