If I'm understanding correctly, the headline on the above article is misleading, as it quotes the article below, which suggests that the bill is more narrowly focused. I haven't actually read the bill, but it's linked from the article below.
House bill extends TSA intel sharing to mass transit
The Transportation Security Administration already shares intelligence it collects with airports. Now a House bill would expand TSA's intel sharing to local mass transit systems as well.
Rep. Jackie Speier (D-Calif.), the bill's sponsor, said the legislation is a "common sense approach" to fighting terrorism. The House passed the bill May 30 and the Senate Committee on Homeland Security and Governmental Affairs is now considering the bill.
