As previously stated the Union Pacific is very serious on trespassers. At every safety meeting and job briefing,we are constantly told to report any activity.
For 2 and 1/2 years I was one of the flag men on the new concrete bridge, that the UP built over the Des Moines river in Iowa.
We were always getting people who just wanted to "LOOK". Gravel road ran under the old bridge. (now dead end) Didn't matter, they were told to leave.
On the other subject of rail the heavier rail is head hardened. Rail from 133-141# would make a perfect anvil. Cut the 3' in half and use for an anvil. Turn the base up on the other piece for a flat surface to beat things flat.
Wear ear plugs!!! After beating on it for a while your ears "WILL" ring.
