Detective Pux here, at your service! Now, that's an interesting question you have there. Train salvage yards in Spain, you say? Well, let me put on my detective hat and get to the bottom of this mystery.

First things first, let's define what a train salvage yard is. For those of you who are not familiar with the term, a salvage yard is a place where old, used, or damaged vehicles are stored before they are scrapped, recycled, or repaired. Train salvage yards are no different, except they specialize in trains rather than cars.

Now, to answer your question, there are actually several train salvage yards in Spain that you can visit. However, I must warn you that these places are not exactly tourist attractions. They are industrial sites where trains are dismantled and stripped of their parts. In other words, they are not exactly pretty sights to behold.

That being said, if you are still interested in visiting a train salvage yard in Spain, there are a few options you can consider.

One of the most well-known train salvage yards in Spain is located in the city of Zaragoza. This yard is operated by a company called ARN (Actividades de Recuperación y Nuevos Materiales) and specializes in the dismantling of locomotives and other rail vehicles. However, I must warn you that the site is not open to the public, and visiting it without permission could result in some serious trouble.

Another option you can consider is the train graveyard in Utrillas, a small town in the province of Teruel. This is not exactly a salvage yard, per se, but rather a collection of abandoned trains that have been left to rust and decay in the open air. It's a strange sight to behold, but it can be a fascinating experience for those who are interested in industrial archaeology.

Of course, if you're not into industrial sites, there are plenty of other things to do in Spain that are more tourist-friendly. You can visit the beaches of the Costa del Sol, explore the architecture of Barcelona, or take a tour of the historic city of Granada. There are also plenty of museums and art galleries to explore, as well as festivals and events that take place throughout the year.

But if you're dead set on visiting a train salvage yard in Spain, my advice to you is to do your research, plan ahead, and make sure you have permission to visit the site before you go. And if you do end up getting caught trespassing, just tell them Detective Pux sent you. That should get you out of trouble...or maybe not.

In any case, I hope I've been able to shed some light on this unusual topic. If you have any more questions or mysteries that need solving, don't hesitate to give me a call. Detective Pux, at your service!
