I was just relaxing on a typical evening. My husband was preparing my favorite pasta (bless him), and I was scrolling through a Facebook Group when I came across this post: someone had posted a picture of the funky fence that runs along the train tracks in San Clemente, CA. I had no idea why something like that grabbed my attention honestly. This is more like my husband’s jam. The post read something like this: “Why is it crooked? What is the purpose? I don’t get it. Seems like it would cost more, doesn’t it?” The image was posted in Dull Men’s Club group, and obviously I stopped scrolling right away. That group has some really interesting posts.
I was intrigued by the post, so I showed the picture to my husband. He was equally surprised and asked me to read comments, maybe there were some good answers. I mean, once you see it, you can’t unsee it. The metal fence bends outward, zigzag in this weird shape—like it melted slightly in the hot sun or someone just messed up at the factory. But, nope, not a mistake; there’s a very smart, very intentional reason for the “bent” look of these fences.
Let’s break it down.
What’s With the Bent Train Fence?
First off, if you’ve ever walked near a set of train tracks—especially in places like San Clemente, where the tracks run alongside pedestrian areas or beaches—you might have seen one of these fences with a kind of “kink” or outward bulge a little more than halfway up.
And no, it’s not an optical illusion. That shape is real, and it’s there on purpose.
These are known as anti-climb fences, and that bend is a deterrent feature. It’s specifically designed to make it harder for people to scale the fence and access the tracks.
Here’s How It Works
Imagine trying to climb a straight vertical fence. It’s hard, but with enough grip and guts, someone could pull it off. Now imagine getting to a certain height—and then the fence curves toward you, basically forcing you to lean back or lose your balance.
That angled section throws off your center of gravity and makes climbing significantly more difficult. The further out it curves, the more awkward (and dangerous) it becomes to continue climbing.
And that’s the point.
These fences are trying to prevent trespassers from hopping onto the tracks—whether they’re thrill-seeking teens, tourists trying to cross quickly, or just people who don’t realize how risky it is. Railways are incredibly dangerous. Trains can’t stop quickly, and there’s no safe place to go if you’re caught between tracks and a train barreling toward you.
So these fences are shaped in a way that prioritizes safety by discouraging people from even trying to climb them.
Why Not Just Make the Fence Taller?
Good question. Taller fences are a thing, but they aren’t always the best solution. Here’s why that outward bend can be more effective:
Cost: Extending the height means more materials and a heavier structure, which can require stronger foundations.
Maintenance: Very tall fences are harder to inspect and repair.
Aesthetics and Viewlines: In scenic areas like beach paths (hello, San Clemente), you don’t want to completely block the view or create an eyesore.
Efficiency: That bend creates a psychological and physical barrier without drastically increasing height.
So instead of going higher, designers go smarter.
Is It More Expensive to Build These Fences?
Probably, yes. That angled section requires precision bending during manufacturing, and the whole setup needs to be strong enough to resist people leaning or pulling on it. But the tradeoff is worth it when you consider the safety benefits and long-term savings from fewer incidents and liability issues.
And don’t forget—railroad companies are constantly balancing risk management, public safety, and urban integration. A smartly designed fence can prevent tragedy and lawsuits.
Do These Fences Work?
Absolutely. Anti-climb fences are used in all sorts of places: prisons, military bases, secure government buildings, and yes—train tracks. The angled design is proven to reduce attempts to scale fences and increases the time and effort it would take to do so.
And in high-risk areas, slowing someone down even by a few seconds can be the difference between life and death.
Why You See Them More Often by the Beach
Places like San Clemente have a unique issue: train tracks running super close to the coast, often with pedestrian paths just a few feet away. That means lots of foot traffic and potential for people to cut across tracks to get to the beach or avoid walking around.
That “shortcut” can become fatal really quickly.
So these angled fences are part of a bigger safety strategy to keep people where they belong—and keep them alive.
So No, It’s Not a Design Error
The next time you walk past one of those strangely bent fences and think to yourself, “Who approved this?”—take comfort in knowing it was not a mistake or an inconclusive contractor trying to get through a bad day. This is instead a clever solution to a real problem, and a method for figuring out safety, cost, and function and making it all work.
Simply put: the bent train fence is not a failed design. It is a brilliant design. And now you know. We enjoyed some very entertaining information over dinner that night. We discussed it while indulging in the wonderful pasta my husband made for us.
