The bill amends the existing law regarding the discharge of firearms and the throwing of objects at trains, specifically targeting the penalties associated with such actions. It replaces the terms "wantonly, maliciously, or mischievously" with "knowingly" to clarify the intent required for prosecution. Additionally, it establishes that individuals found guilty of these offenses will be charged with a Class A misdemeanor, which carries more severe implications than the previous classification.

Furthermore, the bill increases the potential fines for these offenses. The previous fine range of $25 to $250 has been removed, and the new legal language does not specify a minimum or maximum fine, indicating a shift towards a more stringent enforcement approach. This amendment aims to deter individuals from engaging in dangerous behaviors that could harm train operations and public safety.
