Having trouble digging out your car this morning? The CTA was probably a better option to get to work. Unless you lived along the Blue Line. The southbound Forest Park-bound train was delayed up to 20 minuted due to weather-related mechanical issues. Once that started, rush hour got nasty. We already showed you the "tardy slips" the CTA provided riders, but WBEZ's Samuel Vega caught glimpse while waiting for the train.
