If i modify some built in content in 2010.
Is it later possible to deleted the modified content.
And how to I go about restoring the built in contend after that.
Also
Is there a way of seeing which items were built in before I modified them

You cannot delete built in content nor should you modify it. If you want to make changes to the built in content, make a clone of it first, then modify all you want. The clone can be deleted. To restore built in content if necessary, use the "revert" option in CM. I am basing this reply on TR2009. I believe 2010 is similar.
I messed up some built in content as well. I ruined the default CN SD40-2. I was sad about it, then I got cnr's stuff. The sadness left as fast as I could load the first SD40u! Gotta love creators. Sadly, nothing says "Trainz" then the "crappy" built in content!
I've been having trouble with that Revert option. For some reason, I haven't screwed up the engine enough to allow it to Revert (or for some other reason). I suppose I should change the KUID? Deleted half the textures by accident is the main problem.
