Relates to the availability and use of opioid antagonists on trains

This bill requires all trains and train stations operated by public transit authorities in New York to have opioid antagonists (like naloxone) available for overdose emergencies. It directly affects public transit systems, mandating that they stock these medications and provide employee training on their use. Key provisions include amending the Railroad Law to add opioid antagonists to required first-aid kits on locomotives and updating public health and transit authority laws to require the availability of naloxone and staff training. The law takes effect 90 days after enactment, with implementation plans due within 180 days for some authorities.
