My wife and I spent a week away in Spain at the end of May. We attempted to do the whole return trip on trains. We managed to do the return journey by train. But the outward journey was slightly hampered by French rail strikes!
Lots of photos and notes below, including CO2 comparisons. And a description of the joy of French rail strikes.
We travelled 2,000km on electric vehicles, reaching a top speed of 190MPH. Without charging our vehicles' batteries once!
