What or where are the rules/regulations for the transit services operated by Bi-State in St. Louis, Missouri, USA, especially Metrolink? I'd like to know what rules I must follow as a passenger if I go there and ride the trains, and they don't appear to be online.
I am the Online Media Specialist for STL Metro, and I can see your point that rules and regulations may not have a cohesive home on the website.
Are there specific questions I can answer for you? Basic riding rules including must have valid fare, no eating or drinking, no loud music, no pets except for service animals, no leaving your bags unattended.
Having ridden on Metrolink a couple times when there, I'm not sure there ARE any. :(
But here's where the offical answer is buried on their site: http://www.metrostlouis.org/RidingMetro/Overview.aspx
See in particular the "How to Ride", FAQ, and "Safety & Security" sections.
