Regarding security...
The security personnel I've encountered were nothing but polite and professional. Apparently others here that post pictures of construction, within park rules, have dealt with officers less civil, which is disappointing.
If someone was dumb enough to jump a fence, they should indeed be arrested. Especially when all you have to do is point your camera lens though a hole in the fence and press the zoom button.
And I don't even do that anymore. If you look at my recent posts, you'll notice I make sure to include some chain link in the frame to prove that the shot was taken from behind a fence. I've gone out of my way to help spread the word about restricted areas. Frankly, I don't know how more cooperative I can be.
Let me remind our security friends that I am a responsible 38 year old adult male who is married and well aware of the consequences of breaking the rules....
As far as getting pictures of track, which is in a restricted staging area, let the park handle that:
