Last week, the FCC released a Notice of Proposed Rulemaking seeking comment on a Petition filed last year by the National Public Safety Telecommunications Council.  The Petition urged the FCC to amend its rules to permit railroad police officers that are empowered to carry out law enforcement functions to access public safety interoperability and mutual aid channels in the VHF, UHF, 700 MHz and 800 MHz bands.  The Commission tentatively concluded that enabling railroad police officers to use these public safety channels to communicate with first responders would provide a public safety benefit.  The comment cycle will be established when the NPRM is published in the Federal Register.
