City Rail A Set - Design

Design

The sets are formed of eight carriages – a break from the previous standard Sydney practice of four car sets, which are then coupled to form eight car trains. The configuration is: trailer driving car + motor car + motor car + trailer car + trailer car + motor car + motor car + trailer driving car. This means that guards operate from the rear of the train rather than the centre and that commuters are able to walk through the entire train in an emergency. Nightshine Australia was selected to produce luminescent arrow signs line, which are affixed on the base of outer seats on the lower and upper decks to direct passengers the most appropriate route of exit. The trains include external CCTV cameras to assist guards.

Inside, the train includes additional Emergency Help Points and CCTV cameras. Axis Communications was awarded the contract to install the train's extensive system of 98 CCTV cameras, which are linked together with Power over Ethernet and utilise Progressive scanning technology to allow capturing of events in clear high resolution, with no distortion in quick movement individual frames. The CCTV cameras are designed to withstand vibration and features technologies such as an in-built heater to prevent condensation and alarms to alert of removal or obstruction. The train flooring utilises Treadmaster TM8, made from a polymer-based material that is designed to be durable, vandal and graffiti resistant. They are also designed with safety in mind, being highly fire resistant with low smoke toxicity output.

Improvements to the DVAs (Digital Voice Announcements) with differential pitch of the voice allow more natural sounding speech. All the stations included in the stopping pattern are also announced prior to or soon after departure from a terminus stop. ‘Smart’ air-conditioning will automatically adjust to the outside temperature and the number of passengers on board. Accessibility features include 16 wheelchair spaces, portable wheelchair ramps in the end cars, red fabric on priority seating and additional handrails.

The A set is the first passenger train in the world to use LED lamps for all lighting (except headlights). Woollen moquette fabric, a durable, vandal-resistant material first used in the OSCAR trains, Hunter Railcars, and later adopted in the refurbishments of both the Tangara and Endeavour railcars, is used to cover the train's seats. Detailed design of the train was completed in July 2009.

Famous quotes containing the word design:

    If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.
    Henry David Thoreau (1817–1862)

    Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.
    Ralph Waldo Emerson (1803–1882)

    Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.
    François, Duc De La Rochefoucauld (1613–1680)
