Um conceito de comboio interessante
#1
E' um comboio que nao precisa de parar nas estacoes.

[youtube]http://www.youtube.com/watch?v=p9Ig19gYP9o[/youtube]

O que e' engraçado e' que toda a gente acha isto espectacular! Eu olho para isto e penso "mas que imbecilidade!".
Mas mesmo assim tem a sua piada como coisa futurista.

Ufa... Quando vi o título da thread, só me lembrei do "A Centopeia Humana"...
É um filme estranho

epá, não não não. Quando comecei a ver o filme lembrei-me logo de uma coisa inteligente. Mas afinal não era isso que eles pensaram. Era bem mais inteligente se fosse:

Passo a explicar:

O comboio tinha um "anexo" por cima que deslizava sobre calhas. Em andamento estava à frente. Assim que havia uma estação, o comboio principal abrandava e o "anexo" parava, enquanto o resto do comboio seguia em frente, devagarinho. Assim que estivesse pronto (ou que o comboio acabasse, lol) voltava a ir para a frente da carruagem principal.

Hem? Esta minha cabecinha ainda funciona Biggrin (era preciso que o comboio fosse mesmo muuuito comprido, claro ^^)
De todos os fóruns que conheço, este é um deles.

Será que a nova estação de Barcarena já está preparada para este sistema?

A brilliant new Chinese/Taiwan train innovation - get on & off the bullet train without the train stopping.

No time is wasted. The bullet train is moving all the time.
If there are 30 stations between Beijing and Guangzhou...a distance of 2200 KM, just stopping and accelerating again at each station will waste both energy and time.
A mere 5 min stop per station (elderly passengers cannot be hurried) will result in a total loss of 5 min x 30 stations or 2.5 hours of train journey time!


How it works (view the movie - in mandarin though!):


1. For those who are boarding the train :
The passengers at a station embarks onto to a connector cabin way before the train even arrives at the station. When the train arrives, it will not stop at all. It just slows down to pick up the connector cabin which will move with the train on the roof of the train.
While the train is still moving away from the station, those passengers will board the train from the connector cabin mounted on the train's roof. After fully unloading all its passengers, the cabin connector cabin will be moved to the back of the train so that the next batch of outgoing passengers who want to alight at the next station will board the connector cabin at the rear of the train roof.


2. For those who are getting off:
As stated after fully unloading all its passengers, the cabin connector cabin will be moved to the back of the train so that the next batch of outgoing passengers who want to alight at the next station will board the connector cabin at the rear of the train roof.
When the train arrives at the next station, it will simply drop the whole connector cabin at the station itself and leave it behind at the station. The outgoing passengers can take their own time to disembark at the station while the train had already left. At the same time, the train will pick up the incoming embarking passengers on another connector cabin in the front part of the train's roof.
So the train will always drop one connector cabin at the rear of its roof and pick up a new connector cabin in the front part of the train's roof at each station.


What an Innovation?
Peng Yu-lun is a Taiwanese inventor who came up with an idea that promises to help save energy and significantly increase train speeds.
Peng Yu-lun says that a train like the domestic Kaohsiung MRT has a maximum speed of 85 km/h, but due to stops, it achieves an average speed of just 35 km/h. If the train followed his concept, it would be able to maintain an average speed of 85 km/h throughout the entire trip thus saving time and energy.

While the idea sounds great in theory, it does have its flaws. Leaving safety factors aside, the system is restrictive in the sense that some stations are more popular than others ? what happens if more people than the designated car can fit want to get off at a particular station, can you imagine the commotion!

Exactamente. Para alem disso ha' mais coisas:
1- A aceleração e desaceleração das duas mini-carruagens deve ser brutal. Nao estou a imaginar gente de 80 anos a aguentarem tal coisa, duas vezes por dia, cinco dias por semana.
2- E' preciso mais uns quantos motores do que com um sistema normal. E' preciso um motor para fazer a mini-carruagem da frente acelerar e outro para fazer a de tra's parar. E depois de passar pela estacao e' preciso mover a mini-carruagem que esta' no fim do comboio para o inicio do comboio.

Inventor rolls out efficient non-stop train system
07/03/2007 (Taiwan News)

Peng Yu-lun, a resident of Sanwan Township with a penchant for R&D, unveiled his "non-stop MRT system" to the world on Monday. The system avoids trains having to decelerate and stop at station stops, instead taking on boarding and alighting cars on the fly. The system saves energy and reduces equipment costs among other advantages, and Peng has already applied for a patent on his invention. However, Peng himself believes that the technical challenges will still require expert assistance in order to make the plan a reality.

Peng works in a sand and construction materials plant in Sanwan. A previous work of his, "Step Bricks for Recreational Trails", earned him a bronze medal from the Nuremburg International Inventors Exhibition in Germany, as well as a silver medal at the Taipei International Inventors' Exhibition. In 2006, Peng was named an outstanding Taiwanese inventor and received an honorary doctorate.

Recently, Hsinchu and Miaoli have announced their intention to join up in promoting "Hsinchu-Miaoli Light Rail Transit", and this idea sparked Peng's interest, the result being the new "non-stop" system. Peng has applied for patents in Taiwan and China, and was on hand at this year's Taipei International Inventors' Exhibition and the Nuremburg inventors' event as well.

On Monday, Peng publicly announced his hopes to provide a mass rapid transit plan which could be analyzed for feasibility.

Peng used toy trains and track models to come up with his idea. When a train comes into a station, passengers first enter a "boarding" car, which is put into motion ahead of time. After the rear of the traveling train catches up, the car is joined to the rest of the train.

Passengers wishing to get off the train change seats, moving to a designated car. Before they actually arrive at the station where they will alight, that car is detached from the train. The main part of the train continues onward, and the "alighting car" alone stops at the station. Peng says that making good use of these special cars can allow a train to travel its entire route without ever slowing down or stopping at a station.

Taking the Kaohsiung MRT system as an example, Peng says that its maximum speed is 85 kph. Because it must stop at every station, it achieves an average speed over its route of just 35 kph. If the non-stop system were in place, the top velocity of 85 kph could be maintained throughout the system, saving time and energy. Platform equipment and land area required for stations could likewise be reduced. But now the big problem is just precisely how the special boarding and alighting cars will be joined and detached from the main train. Peng says that those are questions that will require participation from experts in order to solve.
