I took this photo during My lunchtime one afternoon, in early March of 2009. A Chicago Transit Authority maintenance worker prepares to go back to work servicing the mechanical safety gates, at the Isabella Street CTA rapid transit railroad crossing, in north suburban Wilmette Illinois. These automatic mechanical chain link motorized fence gates, keep people from trespassing on to the electrified 3rd rail CTA Purple line right of way, preventing electrocution accidents and other liability issues.
