Subject says it all.

My main reason for this suggestion is as follows:
I created train crossings and have walled off my rails inside the base so I don't get killed by a passing train. I have little sections of wall jut out from my main wall to surround train signals and it really bothers me. I want to have nice straight lines if possible. Of course I could just make the wall one block further away but then it takes up even more space then the 4 wide with the walls as close as possible. Another reason I can't do this is because underground belts can't go more than 4 blocks.

I would be happy with just train signals being allowed on walls, but there are some other items that may be good ideas as well.
This other problem could be resolved by allowing walls to be built on top of underground belts. They are going underground after all. Underground pipes and even regular pipes could be as well (though they have a longer underground reach so not as needed)
Small and Medium electric poles could be another to be allowed to build on top of walls, of course they would be susceptible to attack if on the outside of the base.

I guess in implementation they would actually become a single item, but you would get both items back separately if deconstructed. Maybe when placing you would have to shift click to make sure you actually wanted to place the item on the wall.

That's about all I have.

One of the things I'd like to see integrate with walls is turrets. For example, using them as corner posts.

However, I usually end up putting them behind the walls anyway, because they're biter chew toys.

This is a bit of a quirky suggestion though. Walls are typically your first defence against biters and they get damaged / destroyed pretty easily. If you start putting stuff on them then that's going to get destroyed as well. You would just be making a target of your signals which could potentially mess up your rail network. You also don't want turrets on the walls since it makes them a much easier target.

So the request is for fringe cases when you have rail lines going through your base and you've set up walls for it. I don't think this would benefit the majority of players.

Yes it is true that the items built into walls would be susceptible to attack and that is where you would make the choice to do it or not.

I think i may start a different suggestion to make an item like chain link fence that can block the player as an alternate to this idea.
