49 U.S.C. § 20147 — Warning of civil liability

The Secretary of Transportation must encourage railroad carriers to warn the public that they could face civil liability — meaning they could be sued or fined — for two things: vandalizing railroad signs, devices, and equipment that are meant to keep people safe, and trespassing on railroad property. This encourages railroads to post warnings, but the section itself does not create the liability or set penalties — it directs the Secretary to promote awareness of risks that already exist under other regulations.
