Wetter. Warmer. Wilder.
That long-term weather forecast for the Philadelphia region means trouble for SEPTA, especially on its railroad, subway, and trolley routes.
A federal report released this month, which used SEPTA as a case study for the nation's transit systems, predicts that average temperatures in Philadelphia will rise by 3 to 6 degrees by 2050, with greater annual rainfall and more frequent "heavy precipitation events."
That means SEPTA can expect more flooding, sagging rail-power lines, mudslides, toppled trees, and washed-out rail beds.
Already, agency officials are fighting back against climate change, elevating equipment, adding subway pumps, buttressing hillsides, and adding backup power and control systems.
