I did this commute for a year a few years ago. The key for me was to make the commute on either end as short as possible. We lived within a 10 minute walk of Union Station and in Baltimore I could walk or take the bus to my office depending on my mood. That made it much for doable for me. I enjoyed reading on the train — in fact that’s the only thing I miss. The two biggest issues with MARC are that if you have to work just 5 minutes late or your bus is late it could mean missing the train and having to wait 30-45 minutes for the next one. Also the weather can easily bring MARC to a standstill and take down a huge part of the system.
