Marking 125 Years Since the Great Gauge Change
Arnold Reinhold writes "This month ends with the 125th anniversary of one of the most remarkable achievements in technology history. Over two days beginning Monday, May 31, 1886, the railroad network in the southern United States was converted from a five-foot gauge to one compatible with the slightly narrower gauge used in the US North, now know as standard gauge. The shift was meticulously planned and executed. It required one side of every track to be moved three inches closer to the other. All wheel sets had to be adjusted as well. Some minor track and rolling stock was sensibly deferred until later, but by Wednesday the South's 11,500 mile rail network was back in business and able to exchange rail cars with the North. Other countries are still struggling with incompatible rail gauges. Australia still has three. Most of Europe runs on standard gauge, but Russia uses essentially the same five foot gauge as the old South and Spain and Portugal use an even broader gauge. India has a multi-year Project Unigauge, aimed at converting its narrow gauge lines to the subcontinent's five foot six inch standard."
I know I'm stating the obvious for many readers. But that's because post WW2, oil was cheap, and driving equated to the ultimate form of personal freedom. So much freedom in fact that the suburbs were created in that time period too. Of course, cheap energy wont last forever. I can't predict what will happen in the future with regards to transportation, but I can predict that the current status quo will not last.
The problem wasn't our desire for freedom and independence with how we lived our lives. The problem was the instruments of energy we chose to achieve that without a clear vision or plan in mind to maintain it.
Life is not for the lazy.

Still does. Try getting anywhere that's not in New York City, San Diego, or Chicago without a car, and you'll be spending a lot of time waiting or being herded where others want you to go. And you'd better plan in advance, because the bus isn't stopping at that quaint roadside diner you just saw.
I'd like to know which country has an electric grid that makes the US grid look primitive.
I don't think it's so much that the US grid is primitive compared to other countries. Rather it is primitive compared with the available technology and projected needs. The monitoring and control equipment on much of the grid remains rather primitive, the wire infrastructure is fragile (major outages every time a serious storm blows through), many areas still depend on sending a person out to read the meter for billing, there is a too much interdependence without adequate safeguards, local generation (solar, wind, etc) remains problematic in many places, generation sources are relatively dirty, usage controls are primitive, etc. Most of our infrastructure was built decades ago and (IMO) too little was allocated for ongoing upgrades nor were the increases in demand adequately planned for.
The grid works but it's not nearly as robust, efficient or clean as it could be. That's the problem.
