TALLAHASSEE -- Two unions filed a lawsuit Thursday objecting to the state's attempt to side-step an agreement from 2009 to use federally certified union workers in construction of the signal system that will guide trains on the $1.6 billion SunRail commuter line.

The Brotherhood of Railroad Signalmen and the Florida AFL-CIO asked a Leon County circuit judge to remove the company that won the signal bid, a national firm called RailWorks that has a Jacksonville office, and replace it with United Signal, a company covered by federal union and retirement laws.

The unions said they hoped the subcontractor could be removed and replaced by United without any disruptions to the project's timetable, which calls for trains to roll in mid-2014. But, they said, safety was more important than expediency.
