WASHINGTON — A sweeping rail safety reform bill that envisions billions of dollars for Amtrak easily cleared the Senate Wednesday, its passage helped by the Sept. 12 train collision in Los Angeles that killed 25 people.

The bill, which passed by a 74-24 vote, now goes to President Bush, who has not indicated whether he'll sign it. The measure requires more rest for workers and technology that can stop a train in its tracks if it's headed for collision.

Such technology would have prevented the disaster in Los Angeles, the Federal Railroad Administration has said.

The bill caps the hours per week rail crews can work, and bars shifts longer than 12 hours. It adds 200 new safety inspectors for the Federal Railroad Administration and requires the installation by 2015 of technology that can put the brakes on a train if it runs a red light or gets off track.

The bill also calls for Amtrak to receive $13 billion over five years in subsidies, though Congress will have to separately approve the money year after year. The bill reauthorizes the railroad administration through 2013 and provides $1.6 billion for rail safety programs.
