Crime requires: means, motive, opportunity The motive for crime is always present, and is mostly held in check by keeping the cost of means and opportunity high. In this case the opportunity cost is very low. The trains are just sitting there unprotected. And the means - will just grab a crow bar. EDIT: This regulation is well intentioned: https://www.law.cornell.edu/uscode/text/49/28101 https://www.law.cornell.edu/uscode/text/49/28101 The good intention is to allow interstate policing of the railsystem. The bad effect is to prevent local law enforcement 'interference'.
