All About Our New Electric Trains
Here’s the inside of Auckland’s new Spanish-built electric trains arriving from 2013:
And the outside…
- The new ones accelerate and brake twice as fast – a third as fast as a jumbo jet on full thrust
- Can do 0 to 60km in 24 seconds compared to 40 seconds
- Faster, quieter
- Have twice the number of air conditioning and heating units
- The doorways are 150mm wider
- Maintenance costs will be halved.
- Maximum power of 2720kW– existing trains are hauled by locomotives with a power of 1800kW
- Maximum speed of 110km/hr; the same as most of the existing trains but with the increased power this speed will be achieved more frequently
- Each car will have 77 seats compared with 66 seats on the existing cars
- 2 air conditioning units in each car will provide twice the air conditioning power of the existing trains
- Each car is three metres longer than the existing cars
Other facts about the new EMUs:
- Each car will be formed from 3 cars, one trailer car in the middle and a powered driving car at each end. The 3 car unit will operate in service as a single unit or as 2,3 car units couple together.
- Each car can carry 120 passengers.
- The trains are made from stainless steel and meet latest crash standards.
- They will be powered by the overhead 25kV supply through a pantograph on the roof of each train.
- Each train will be fitted with regenerative braking allowing energy to be produced by the train and fed back into the supply when the trains brake. This provides a considerable improvement in the efficiency of the trains allowing recovery of up to 20% of the energy used.
- They will be quiet, much quieter than the present trains.
- The trains have a life of more than 40 years.
- The trains used a state of the art propulsion system using IGBT technology to control the electric drive motors in an efficient manner. On board computers control and monitor each of the systems and equipment and provide real time information to the crew.
- Each car will have 2 doorways on each side located about 1/3 and 2/3 along the length of the car. The doors will be a sliding plug type proving a good weather and soundproof seal and will have an open width of 1450mm to make sure the swell times at stations are kept to a minimum. Doors are fitted with obstacle detection and will automatically open and re close is something is trapped.
- A dedicated space will be identified for wheelchair passengers with easy access to the platform.
- Space will be provided for bicycles alongside an area for people with restricted mobility such as elderly or mums with small kids.
- The units will have state of the art passenger information systems with both visible and audible information.
- All cars have air conditioning.
- An on board CCTV system will operate in all covers providing images to the driver from 16 cameras.
At peak times the trains will operate six trains an hour from Papakura in the South, on the Eastern line and from Swanson on the Western line.
The extra trains increases rail stock from 148 cars to 171.
AT predicts the number of trips on the Auckland rail network will increase from 9.7m a year to 17.3 m by 2016.
