Innovation in Railways: Decarbonization And Infrastructure-Inspecting Drones
Today, we start a series of videos dedicated to a topic that is now relevant more than ever before - innovations in railway traffic!
Among others, there are zero-emission hydrogen trains, advanced autonomous trains able to handle even emergency situations, drone-based automation of infrastructure maintenance, implementation of 4G technology in train management systems, implementation of big data technology for improving the safety, security and reliability of rail infrastructure, artificial intelligence used for real-time traffic simulations and delay forecasting, variable railway bogies allowing a single train to operate at two or even more different track gauges and many, many other.
There’s a good reason why innovations find their way to railways so easily. On one hand, rail technology continues to develop as rail customers are demanding faster, safer and more reliable service, while on the other, the railway system is, by definition, suitable for automation of certain processes due to fact that the freedom of movement of trains is, well, taken away by the rails.
However, as this aspect of railways has been always super interesting to us, we decided to share with you some thoughts, and to introduce you with the recent trends in this field. As, of course, it is impossible to cover all rail-related technological breakthroughs and innovation trends in one single video, we are now going to speak only about two - decarbonization and automation of infrastructure maintenance.
Now, let’s start!

How will people travel in the future? | The Economist
Hollywood movies have envisaged a future of hoverboards and flying cars - these imaginary machines might not be too far from reality. By 2030 a quarter of shared passenger miles traveled on America's roads could be in self-driving vehicles. It's believed eight out of ten people will be using Robotaxis in cities where available by 2035. There will also be more emphasis on sharing journeys. All this could reduce the number of cars on city streets by 60 percent, emissions by 80 percent, and road accidents by 90 percent.
And then there are flying cars - or more accurately - passenger drones and helicopter hybrids. Uber is investing heavily in this technology. Los Angeles, Dallas, and some states in Australia could see test flights within a couple of years - but these cross city flights will require changes to air traffic control systems, which will probably take longer to develop than the flying vehicles themselves.
Traveling across country could be far quicker too. China is leading the world in high-speed bullet trains that are capable of traveling over 400 kilometres per hour. By 2020, 80 percent of the country's major cities could be linked to the network. But for high-speed travel, the ambitious Hyperloop could leave bullet trains in the dust. It's an ambitious system in which pods move along tubes in a mere vacuum. The lack of air resistance means pods could reach speeds of over 1,000 kilometers per hour.
Virgin wants to deliver a fully operational Hyperloop system by the mid-2020s. The company claims its Hyperloop pods could travel from Los Angeles to Las Vegas in 30 minutes. But the potential dangers of travel at such great speeds, and the cost, mean the Hyperloop will not be a reality for decades.
In the air, the makers of supersonic jets are promising to slash travel times too. Arion wants to carry 12 passengers in luxury at 1.4 times the speed of sound - about 60% faster than typical aircraft today, and rival Boom hopes to be flying its supersonic airliner by 2023, carrying 55 passengers up to 2.2 times the speed of sound.
Skeptics say these ideas are impractical and expensive, with many technical challenges to overcome. Despite this, tech and engineering companies are boldly taking up the challenges of passenger transit - promising to propel us into the future.

Alemania empieza plan piloto para que el transporte Publico sea Gratis y asi bajar la contaminacion
Empiezan con 5 ciudades, con plan piloto, para luego expandirlo a todo el pais, y usarlo de modelo en todas las ciudades europeas.

Germany mulls free public transport to quash air pollution menace

“Car nation” Germany has surprised its European neighbours with a radical proposal to reduce road traffic by making public transport free, as Berlin scrambles to meet EU air pollution targets and avoid big fines.
The move comes just over two years after Volkswagen’s devastating “dieselgate” emissions cheating scandal unleashed a wave of anger at the auto industry, a keystone of German prosperity.
“We are considering public transport free of charge in order to reduce the number of private cars,” three ministers including Environment Minister Barbara Hendricks wrote to EU Environment Commissioner Karmenu Vella in the letter seen by AFP Tuesday.

Air pollution legal action decision due in mid-March
The European Commission will decide next month whether to launch legal cases against nine member states that are accused of breaking air pollution action, after additional information was submitted at the eleventh hour.The proposal will be tested by “the end of this year at the latest” in five cities across western Germany, including former capital Bonn and industrial cities Essen and Mannheim.
The move is a radical one for the normally staid world of German politics – especially as Chancellor Angela Merkel is presently only governing in a caretaker capacity, as Berlin waits for the centre-left Social Democratic Party (SPD) to confirm a hard-fought coalition deal.
On top of ticketless travel, other steps proposed Tuesday include further restrictions on emissions from vehicle fleets like buses and taxis, low-emissions zones or support for car-sharing schemes.
Air pressure
Action is needed soon, as Germany and eight fellow EU members including Spain, France and Italy sailed past a January 30 deadline to meet EU limits on nitrogen dioxide and fine particles.
Brussels environment chief Vella gave countries extra time to present further pollution-busting measures or face legal action.
“Life-threatening” pollution affects more than 130 cities in Europe, according to the Commission, causing some 400,000 deaths and costing 20 billion euros ($24.7 billion) in health spending per year in the bloc.

Germans ready to ditch cars in favour of buses, trains and bikes
German motorists are ready, in theory at least, to abandon their cars in favour of buses, trains and bikes, according to a new study. EURACTIV’s partner Der Tagesspiegel reports.Even without the pressure from Brussels, air quality has surged to the top of Berlin’s priorities over the past year.
Suspicions over manipulated emissions data have spread to other car manufacturers since Volkswagen’s 2015 admission to cheating regulatory tests on 11 million vehicles worldwide.
Environmentalists brought court cases aimed at banning diesels from parts of some city centres, and fears millions of drivers could be affected spurred Chancellor Angela Merkel into action.
Titans like BMW, Mercedes-Benz parent Daimler or the world’s biggest carmaker Volkswagen agreed to pay some 250 million euros into a billion-euro fund to upgrade local transport.
The government “should make sure that the car manufacturers finance the emergency measure” of free transport, Greenpeace urged, adding that more parking and road tolls in cities could help reduce urban traffic.
On their own account, the auto firms have stepped up plans to electrify their ranges, with a barrage of battery-powered or hybrid models planned for the coming decade.

Germany's energy and climate policy is taking shape
The coalition agreement between the German Conservatives and the Social Democrats outlines a relatively ambitious energy policy. EURACTIV’s partner Le Journal de l’environnement reports.Feet of clay
Public transport is highly popular in Germany, with the number of journeys increasing regularly over the past 20 years to reach 10.3 billion in 2017.
In comparison with other major European nations, tickets can be cheap: a single ticket in Berlin costs €2.90, while the equivalent on the London Underground costs €5.50 euros.
But cities were quick to warn that more planning was needed if free travel was to succeed.
“I don’t know any manufacturer who would be able to deliver the number of electric buses we would need” to meet increased demand if transport was free, Bonn mayor Ashok Sridharan told news agency DPA.
Meanwhile, Association of German Cities chief Helmut Dedy warned that “we expect a clear statement about how (free transport) will be financed” from the federal government.
Other attempts around the world to offer citizens free travel have failed, including in US city Seattle.
Ministers “should think again during a ride on the U6 (underground line) in Berlin at 7.30 am,” Die Welt newspaper commented.
“The conclusion would be clear: more carriages, more personnel, and maybe even more tracks and lines would be needed. Where would the billions for that come from?”

Perú se convertirá en el segundo país en el mundo en certificar bonos de carbono en el sector ferroviario
Se estima que un tren de seis vagones puede transportar a 1200 personas y solo emite 4 gramos de gases de efecto invernadero, mientras que se necesitarían 25 buses para transportar la misma cantidad de personas y emitirían 600 veces más de estos gases.
Poul Kudsen, especialista en Intermodalidad de Transporte de la Unidad de Gerencia de Desarrollo del Metro de Lima y Callao, destacó la importancia de que el Perú reciba esta certificación, emitida por Verified Carbon Standard (VCS), ya que el sector transporte es uno de los que emite más gases contaminantes a nivel nacional. Sus emisiones representan el 15%, mientras que en la industria es del 4%.
