Battery Electric Freight Trains can Help Reduce Emissions

- Adam Clare

Trains are great for efficiently moving freight long distances and are used the world over. Many regions already have all electric rail systems, but in North America electric adoption hasn’t happened. Historically, this has been due to the installation and maintenance costs for the vast distances of overhead electric wires. Advances in battery technology hopes to change this.

An American company, Wabtec, built and tested their FLXdrive engine last year and found it worked rather well. The engine is built on the same platform as their Diesel engines but runs off of batteries more powerful than a Tesla’s and can regenerate energy with braking.

However, the environmental benefits of rail have been undermined by the heavy reliance upon diesel to fuel freight trains, as well as a widespread preference among businesses to move goods via trucks rather than trains. This is a problem globally beyond the U.S. — the International Energy Agency has said that freight rail is “often neglected” in climate debates and currently carries only seven per cent of all freight moved around the world.

…

A greater tonnage of goods is now moved by trucks on roads than by rail, however, and the rail industry hopes action on the climate crisis will prove advantageous to its own prospects. “If we decarbonize all of the locomotives and decrease the number of trucks, we will get to where we need to be,” said Gebhardt. Medium and heavy-duty trucks are responsible for about a quarter of all U.S. emissions from transportation, according to the Environmental Protection Agency, more than double the pollution emitted by aircraft.

Leaded Gas for Cars Impossible to Buy Globally

After decades of effort by environmentalists leaded gasoline for use in automobiles is impossible to buy anywhere on the planet. Last month Algeria ended sales for leaded gasoline which marked the end of the dangerous fuel for consumers according to the UN Environment Programme. All gas burning is bad for people and the planet, but leaded gasoline use was the worst.

The next step in getting rid of leaded gasoline is to ban it’s use in airplanes.

Petroleum containing tetraethyllead, a form of lead, was first sold almost 100 years ago to increase engine performance. It was widely used for decades until researchers discovered that it could cause heart disease, strokes and brain damage.

UNEP cited studies suggesting that leaded gas caused measurable intellectual impairment in children and millions of premature deaths.

Most rich nations started phasing out the fuel in the 1980s, but it was still widely used in low- and middle-income countries until 2002, when the UN launched a global campaign to abolish it.

This Drone is Hitting the Rails

- Adam Clare

In order for train travel to be safe the rails the trains ride on need to be of a certain quality. You don’t want the equivalent of a pot hole on rails. In order to maintain good tracks workers need to shut down the rail line and physically go out to the rails. This delays trains, and therefore travelers. Nordic Unmanned, a Norwegian company, has created the BG-300 drone which is designed to monitor rail quality without having to alter train schedules.

As it does so, it inspects the tracks utilizing cameras and “other sensors,” plus it can lubricate rail switches if required. Importantly, though, if it encounters any other rail traffic, it will autonomously fly up off the tracks in order to get out of the way until that traffic passes. It can also use this functionality to move from one track to another.

As a result, stretches of rail lines do not have to be closed to trains while inspections are being performed. Such is not the case with traditionally used inspection vehicles, such as trolleys or rail-wheel-equipped trucks.

It’s Time to Destroy Highways to Build Cities

- Adam Clare

People make cities an interesting place to be. It’s the people that produce culture and economic prosperity, yet many cities have highways going right through them. These highways make the city worse in every regard.

Now, cities in America will be getting funding to repair the cities from the damage done by highways. Hopefully other parts of the world will see that highways are a thing of the past and we need to build cities for people.

The future of the country’s highway system is about much more than those neighborhoods, too. It will also affect public health and climate change. And the debate is happening at a fascinating moment: Many of the midcentury highways are reaching the end of their life span, and attitudes toward transportation are shifting.
…
“As recently as a decade ago,” said Peter Norton, a University of Virginia historian, “every transportation problem was a problem to be solved with new roads.” That’s not always the case anymore.

Ending the Gender Gap in Transportation

- Adam Clare

There is a gender gap in our cities and it’s all thanks to car-centric design. Everybody knows that cars destroy urban centers and cause a lot of harm to public health. but you may not have thought of the impact cars have on gender. As cities look to modernize themselves by returning streets to people they need to also think about how different people use transportation in the city. Part time workers are more likely to be women and that often means more trips per day than their typical male counterparts. Designing cities through a gendered lens means that the city can accommodate multiple modes of transportation beyond the male-dominated rush hour.

“The discussion on inclusive mobility is gathering steam,” said Ricarda Lang, deputy chair of the German Green party. “Feminism is not a stand-alone topic, but a perspective that we also apply in the area of urban development and mobility.”

The issue is more complex than cars versus bikes. In some cities, women cycle less, likely because lanes aren’t wide or secure enough, especially with kid carriers — underscoring the importance of transport design. But there’s no denying car-centric systems face strain.

Numerous grassroot initiatives are demanding restrictions on personal vehicles. One of the most radical is in Berlin, where activists are pushing for a referendum that would all but eliminate private autos in the inner city in favor of walking, cycling and public transport.
