Here's some background information about the Metropolitan Transportation Authority (MTA), which serves 15.3 million people across New York City, Long Island, southeastern New York state and Connecticut.
The MTA is the largest public transportation network in North America.
It is run by the state of New York, not the city government.
MTA is partnered with Operation Lifesaver, a national rail safety organization.
MTA has produced nine "generations" of the "If You See Something, Say Something" campaign, which encourages customers to notify the police and MTA employees of suspicious activity.
The MTA network includes these agencies: MTA New York City Transit, MTA Bus Company, MTA Long Island Rail Road, MTA Metro-North Railroad, MTA Bridges and Tunnels (B&T) and MTA Capital Construction.
