It's been fine lately. I do the Camden to Union Station commute three times a week. I wish we had later train options and more than once an hour, but honestly, it's been more reliable the last few months than it has been in a while (been taking the Marc since Fall 2020). Best positive it that it's walking distance from home and if I miss the last Camden line I can still use my monthly pass on the Penn line but will either have to take a cab or ask my partner to pick me up.
