NS 93
The NS 93 (Neumático Santiago 1993) is the third generation of rubber tired rolling stock used on the Santiago Metro system. The trains were manufactured by GEC Alsthom in 1996 and went into operation in 1997. Originally designed for use on Line 5, the trains first operated on Line 2 prior to the opening of Line 5, and today work on the lines 1 and 5. Features The NS 93 series is based on the design of MP 89 series from the Paris Métro, along with sloped ends, automatic doors and through gangways from car to car. However, the NS 93 is slightly taller than the MP 89 to accommodate air conditioning, and they operate in 6 car formations on Line 5 (SN-NP-NNS), 7 car formations on Lines 1 and 5 (SN-NP-NRNS), and 8 car formations on Line 1 (NNS-NRNS). As a result, the trains can operate in six-car , seven-car , and eight-car lengths, depending which line they are assigned to. The length of each car is ( for cars containing the driver's cab). The interior of the NS 93 is graced wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wheel
A wheel is a circular component that is intended to rotate on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of Axle, axles. In order for wheels to rotate, a Moment (physics), moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumer, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word '':wi ...

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Wheel Tread
A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle such that both wheels rotate in unison. Wheelsets are often mounted in a bogie ("truck" in North America) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle. Most modern freight cars and passenger cars have bogies each with two wheelsets, but three wheelsets (or more) are used in bogies of freight cars that carry heavy loads, and three-wheelset bogies are under some passenger cars. Four-wheeled goods wagons that were once near-universal in Europe and Great Britain and their colonies have only two wheelsets; in recent decades such vehicles have become less common as trainloads have become heavier. Conical wheel-tread Most train wheels have a conical taper of about 1 in 20 to enable the wheelset to follow curves with less chance of the wheel flanges coming in contact with the rail sides, and to reduce curve resistance. The rails generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Système D'aide à La Conduite, à L'exploitation Et à La Maintenance

Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MP 89
The MP 89 (French : Métro sur Pneus d'appel d'offres de 1989) is a rubber tired variant of electric multiple units used on the Paris Métro. Designed by Roger Tallon, two types are built by GEC-Alsthom for service on Lines 4 and 14, and soon to be Line 6. The trains on Line 1 were moved to Line 4 between 2011 and 2013 to replace the older MP 59s, though only 48 trains are used for revenue service. The remaining four trains are stored either at Montrouge or Saint Ouen as operational spares. Conception In 1978, RATP possessed a large number of outdated Sprague-Thomson trains, many of which were rapidly approaching 60 and 70 years old. With the MF 77 trains in place along Lines 8, 9 and 13, most of the Sprague were replaced. However, there were still some trains in service along Line 9, which were approaching 80 years old. Those trains were finally retired in 1983, reducing the average age of rolling stock to 14 years. Anticipating further aging in its rolling stock, RAT ...
