Finland announces migration of its rail network to international gauge

In Spain, we already deal with both Iberian and standard gauges—trains like the Talgo models can change gauges with minimal delay. It's not seamless, but it works reasonably well. Spain also has the world's second largest high speed train network.

What the EU could really benefit from is greater support for small companies and independent freelancers who are driving innovation. Unfortunately, governments (Spain included) often treat them as revenue sources, with high taxes and complex regulations, while large corporations can navigate around much of that with ease.

There's no defensive reason for this other than in the cabinet talks.

First of all it's not just so easy to destroy infrastructure in a way that can't be rebuilt quickly; thousands of miles of train tracks would be difficult to destroy. This is happening all over Ukraine.

Second, blowing up your own country's rail infrastructure means you can't use it, either, which means you lose an advantage you have that your trains can move on your rails but your enemy's cannot.
