Gov. Larry Hogan has applied for $27.8 million in federal money to put toward studying a magnetic-levitation railway to connect Baltimore to D.C.

That technology is popular in Japan, where a maglev train recently broke the land speed record for rail vehicles, traveling at 375 miles per hour. (The record it broke was one that it had set less than a week before.) Hogan reportedly went 314 mph on his maglev train ride in Japan on his trade visit to Asia.A Baltimore-D.C. maglev line would get from Point A to Point B in something like 15 minutes.

Itโ€™s a little strange that Hogan would be psyched about a maglev line, which could cost $10 billion total to build (and which even after Japan puts up $5 billion is still a lot of money), when heโ€™s been so critical of the Purple Line for being too expensive.

Also, if youโ€™ve been paying attention youโ€™ll no doubt have noticed that this is not the first time the idea of high-speed maglev travel between D.C. and Baltimore (and beyond) has been floated. So far, the futuristic allure has always run up against practicality. And itโ€™s enough to turn even the most fervent maglev enthusiast into a naysayer.

โ€œIt would make no sense to build such a high-speed system unless you are going to go further, presumably at least to New York if not to Boston,โ€ John Harding, the former chief maglev scientist at the Federal Railroad Administration, told WAMU. โ€œIt would be very hard to imagine that the ridership and fares would be sufficient to support such an expensive system, because obviously there are other alternatives which I would think would be much less expensive.โ€

But, hey, weโ€™re the only ones applying for that $27.8 million so might at least get that.
