The likely answer is somebody took a budget, took some basic measurements of “train in Spain” and didn’t do the follow up on questions like “what’s the max dimensions” before putting in orders for hardware to a place like Japan or china. The trains are probably really good, but exceed max limits because numskulls would rather lock in contracts without ensuring that they are contracting for goods/services they can actually use, and that meet their requirements. Investors are gonna be pissed, because now more money is gonna be needed and more time to get returns because someone somewhere didn’t do their jobs right.
