Sorry but no. I used to live in Frederick and took the MARC train and drove. It took less time during peak rush hour to train than drive, and less time EARLY morning (4-5:00) to drive. I now take the bus from C.H. to Metro Center and then metro out to Silver Spring. It takes me 1 hour (5:00 leave time) to 2 hours (6:30-7:00 leave time)to drive in, and it takes 1.5 hours minimum to drive home regardless, and it takes me 1.5 hours to bus/metro anytime. Thus, the bus is as fast or faster than driving.
