Can I build in my sleepers?

[Rooney]

As you can see in the pictures, my railroad ties aren't very pretty. Removing them seems like a huge project, but what do you think about building around them with pressure-treated wood? I first thought about covering them with landscape fabric (maybe unnecessary?) and then screwing on standing pressure-treated boards on the side and possibly having horizontal pressure-treated boards on top.
Some of the ties are a bit half-rotted at the front, but they are stable and don't lean.

That should work, right?

That's what I would have done too. They seem to be support walls for the passage. If you remove them, you'll need to cast a wall and redo the passage. Your construction will surely last for 10 years at least.

What a huge job to cover all those angles and corners and make it "tight".
How are the sleepers attached, what keeps them in place?

Maybe light green paint can make it look like pressure-treated wood.

They are nailed into each other with long nails.

Since it's been a while since I asked the question, I've already started the work. However, I have removed the top two sleepers and replaced them with new ones, and also cut all the sleepers at the front.
Before I cover them with geo fabric and pressure-treated wood, I will oil them with sleeper oil.

I can attach pictures when the work is done.

It contains, among other things, wood oil and pine tar.

Sounds good that it is creosote and arsenic free.
