## Resource

U.S. passenger rail is an open network. Airport-style checkpoints do not scale across hundreds of stations and platforms. Effective security is layered and intelligence led: visible policing and K9 presence, randomized checks, strong reporting and intel sharing, and fast incident response and recovery. The real high-leverage work sits in the cyber-physical stack that moves trains safely: signals, interlockings, dispatch, power, and communications. The post lays out a clean threat model, clarifies federal and operator roles for “critical rail,” and closes with practical guidance for travelers as well as feasible improvements for policymakers and operators. https://www.thesecuritynexus.net
