WASHINGTON (AP) – As Congress considers spending more on rail security, records show that the Homeland Security Department has spent less than 7 percent of the $10 million it received this year to inspect and patrol rail lines.

Senators began debate on the Homeland Security Department’s overall budget Monday, a month after a committee slashed $50 million for railway security. Lawmakers are expected to restore that money because of the London transit bombings, and Democrats are looking to add $350 million more.

Democrats also say that the Bush administration hasn’t moved quickly enough to spend the money it already has. Congress approved $150 million in local grants for upgrading transit security beginning last October, but the money didn’t begin flowing until April.

Lawmakers also gave the Transportation Security Administration $10 million to make sure rail systems are taking enough precautions to prevent terrorist attacks. But spending reports show that as of May 31 – two-thirds of the way into the federal budget year – the TSA had made plans to spend only $711,000.

And it had yet to spend any of the $2 million for canine teams to patrol rail and subway stations in search of explosives.

“How hard is it to spend money that’s already been allocated, especially since these security measures are so badly needed to protect America’s commuters?” asked Mississippi Rep. Bennie G. Thompson, ranking Democrat on the House Committee on Homeland Security.

Sen. Charles Schumer, D-N.Y., accused the TSA of “slow-walking the critical security projects and initiatives that will help to make our commuters and our country safer.”

Telephone calls seeking comment from the Homeland Security Department, which oversees the TSA, were not immediately returned.

Rep. Harold Rogers, R-Ky., who chairs the House Appropriations Homeland Security subcommittee, is among those in Congress who say that TSA focuses too much on security for air travelers at the expense of surface transportation. The TSA spends about $5 billion annually on aviation security.

Last year, Rogers’ subcommittee ordered the Homeland Security Department to submit a five-year plan outlining how it would secure all transportation modes. The committee still is waiting for the plan.

The Madrid railway bombings that killed 191 people in March 2004 focused attention on rail security. Two months after the attacks, Homeland Security officials issued the first federal security directive to protect rail passengers from terrorism.

Railway operators were required to designate security coordinators, remove trash cans in some places and erect vehicle and pedestrian barricades in others. TSA inspectors are supposed to make sure the order is carried out.
