Japan Will Build Blazingly Fast Tokyo to Osaka Maglev Train Japan Will Build Blazingly Fast Tokyo to Osaka Maglev Train

Imagine making it from New York to D.C. in 45 minutes. That's how quickly Japan's maglev train will make it from Tokyo to Nagoya.

The route between Tokyo and Nagoya, Japan, stretches about 225 miles, the same distance that separates New York City from Boston and from Washington, D.C. For more than three decades, Japan has been considering building a train that would cut travel time between Tokyo and Nagoya to about 45 minutes. The line would use maglev technology, which channels magnetic force to levitate the train almost four inches above the track and propel it forward at speeds over 300 miles per hour.


But building a maglev train requires more money than most people can imagine: The cost for a route covering the 320 miles from Tokyo to Osaka has been pegged at 9 trillion yen or roughly $112 billion. Because of the cost, Japan has dithered over the project for years, until last month, when the government gave the Central Japan Railway permission to go ahead with it.

Imagine making it from New York to D.C. in 45 minutes instead of four hours, East Coasters. Imagine making it from Boston to D.C. in an hour and half, instead of nine. West Coasters, you could be flying from Los Angeles to Las Vegas in under an hour. Getting from Minneapolis to Chicago could take no more than an hour and twenty minutes. That’s what a train like the one Japan is building would mean in the United States.

Adopting this technology, though, requires long-term vision about transportation, which the United States has been lacking lately. Because the trains run on electricity, they’re already cleaner than fuel-burning trains, and as clean energy projects like solar and wind come online, maglev trains can pull power from those sources. But on top of the cost, building a maglev system takes time: The Tokyo-Nagoya branch of the Japanese train won’t be finished until 2027, sixteen years from now.

The system’s high cost comes in part from Central Japan Railway’s decision to make the route as straight as possible, sending it under mountains. (The trains will run through tunnels for 60 percent of the ride.) While high-speed trains like Amtrak’s Acela can run at slower speeds on tracks designed for traditional trains, maglevs require unique rail infrastructure, an expensive proposition.

Once they’re built, however, maglev tracks last longer. The trains we ride right now scrape metal wheels against metal rails, which wear down relatively quickly. The only friction between maglev trains and their track is air friction, easier on the metal tracks. The longevity of the infrastructure is an important selling point. To date, the cost of building maglev trains has outstripped any profits, and the trains will have to run efficiently for many years, with low overhead costs, to make financial sense.

In the United States, the most likely maglev train project is an L.A. to Las Vegas route, an idea that’s been floating around for two decades or so and has received a trickle of government funding. Its estimated total cost would come to $12 billion, a pittance compared to the Japanese project. At least one member of the administration, however, has been impressed by what maglev trains can do. Current Secretary of Transportation, Ray LaHood, took a ride on Japan’s maglev test track last year. His reaction: “I have to say, those trains are fast. Very fast."

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

Bernie Sanders' presidential campaign looks to be getting a huge big shot in the arm after it's faced some difficulties over the past few weeks.

Alexandria Ocasio-Cortez, a leading voice in the Democratic parties progressive, Democratic Socialist wing, is expected to endorse Sanders' campaign at the "Bernie's Back" rally in Queens, New York this Saturday.

Fellow member of "the Squad," Ilhan Omar, endorsed him on Wednesday.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
