That's the short version of a law that you probably don't know exists.

Everybody loves using train tracks as the background for photos. Standing on them though, is illegal! Touching anything that belongs to the railroad companies is illegal.

Apparently, the railroad is very cranky about people messing with their stuff. The Texas Penal Code says:

A person commits an offense if the person:
(1) throws an object or discharges a firearm or weapon at a train or rail-mounted work equipment;  or
(2) without the effective consent of the owner:
(A) enters or remains on railroad property, knowing that it is railroad property;
(B) tampers with railroad property;
(C) places an obstruction on a railroad track or right-of-way;  or
(D) causes in any manner the derailment of a train, railroad car, or other railroad property that moves on tracks.
(c) An offense under Subsection (b)(1) is a Class B misdemeanor unless the person causes bodily injury to another, in which event the offense is a felony of the third degree.

You should probably stay off the new trolley tracks El Paso is installing too. I doubt the city is going to be any cooler than the railroads.
