Amtrak is tapping into the rail fan community to help keep the nation’s passenger railroad safe.

Through a new program dubbed Partners for Amtrak Safety and Security being launched Tuesday, Amtrak will recruit people who are already watching and riding trains to keep an eye out for suspicious activity on trains and around stations and tracks.

Passengers and rail fans can register online to participate in the “neighborhood-watch style program.” They’ll be issued membership cards and learn more about what safety and security concerns they should look out for and how to report.

Amtrak Police Chief John O’Connor says rail fans are already out watching trains and tracks across the country every day and they’ll notice if something is amiss.
