To Bullet Train, or Not to Bullet Train: Why not do Both?

The Free Gauge Train
New Tech in Testing

This past weekend, the Asahi Shimbun reported that the Kyushu Railway Company began testing a very special supertech rail vehicle: the Free Gauge Train (FGT). It's special because it can do Bullet Training, but can also tighten up and get its Local Train on.

The trick is that the train’s wheels - or whatever we call those huge steel discs, because "wheels" seems awkward - can vary the train's lateral wheelbase to fit whichever track it needs to ride. It might seem a simple technology, but it’s totally not - this prototype high-and-regular-speed train is 17 years in the works, and is the first of its kind in Japan.

So, okay yeah, being able to narrow down the train’s lateral footprint is pretty cool, but why do that?

Because it’s Really Expensive to Build Two Sets of Tracks, Two Rail Yards (real estate is expensive), Two Kinds of Maintenance Equipment, Etc., Etc.
Now, Japan is famous for its high-speed rail this and that, the safety and super fast & comfy and on and on - we’re not here to reinvent the standard intro on the what, who, and how of J-rail. It’s the Japanese bullet train. The Shinkansen.* It’s awesome. You really should already know that.

But okay, if you are not hip to the Shinkansen, it's like this:
Even the oldest, cheapest Shinkansen seat is like airline first-class…but better, because you can get up and walk around anytime. To the vending machines. Maybe even the smoking room. Or like, just because you want to walk. Most trains have electrical outlets. They're super clean. Most have 3G wireless; some have wi-fi. There’s a roving food card selling souvenirs and boxed lunches and beer. A nice little hook for your jacket. Spacious bathrooms. No ridiculous security checks. Approximately 160-180 MPH (270-290 KPH). And, they're renowned for being aggressively on-time.

Naturally, all that awesomeness comes at considerable cost to companies and customers, and a very large chunk of overall expense lies in the Shinkansen’s specialized construction and maintenance equipment. Express and commuter trains can’t run on Shinkansen tracks (and probably never will/can/should), and that cannot be helped, but with a train like this, high-speed cars could switch to the smaller tracks, and that would add yet another notch to the Bullet Train's Awesomeness Belt.

So, after 3 more years of testing, if it turns out that this guy right here can do both, everybody wins.

*Guess what, Shinkansen just means “New Main Line.” Which is kinda disappointing, right? It should mean something like “Four-Bladed Throwing Knife.” So sad.

Long before Michael Bay, and even before Hasbro's incarnation, Transformers were Takara Tomy's Microman and Diaclone, and Nintendo's Super Mario, long a global phenomenon, was first a game for Nintendo's Japan-only Famicom console.

If it weren't for the wear and obvious age of the cars and elevated tracks, you'd be forgiven for judging the Tokyo Monorail as futuristic and technologically marvelous. And even if the big, big city is old hat, it's hard not to be moved by that ride - but what's holding up the 51-year-old inverted anachronism?

What I personally like about the Yurikamome is that, because you are gliding above the ground and between buildings on a winding track, it feels as though you’re traveling through the city aboard some kind of hover car.

Japanese Technology from the Future Friday! -

This week it looks like India is going to add Japanese train tech to their cart even though the pirated Chinese knock-offs oooops we mean "models" are cheaper, and here at the Tokyo Game Show, Square Enix has introduced a new company, Shinra Technologies, which they hope will kill all gaming hardware...kinda!

If you have landed or departed from Tokyo International Airport (A.K.A., Haneda Airport), you might have taken Tokyo Monorail. Tokyo Monorail started operation 50 years ago, in 1964. It was the year of the Tokyo Olympics in Tokyo, and since then, it has been one of the main accesses to get to Tokyo International Airport.

"Human Accident" -

It was approaching 4pm on a Monday afternoon in December last year, and I had just finished an interview with a company in Kawaguchi City, Saitama Prefecture, just outside Tokyo. It was time to head back into the city, but when I arrived at Nishi-Kawaguchi train station and saw the mass of emergency vehicles lined up outside, I realized that one of those all too common delays, a Jinshin Jiko (人身事故), a “human accident,” had likely occurred. It’s a curious euphemism.

Rapi:t collaborates with the new Mobile Suit Gundam movie, Mobile Suit Gundam Unicorn.

Rapi:t, a popular sharp-looking rapid train running between Kansai International Airport and Namba in Osaka, is normally colored in blue. However for a limited time until the end of June, the exterior of some of the Rapi:t trains has been changed to red, which is the color of Gundam's enemy, Neo Zeon. The special trains will make a maximum of 8 round trips every day.
