Regarding the above comments, i'll just say that sending the in place of the when it doesn't run is not a bad idea(weekends, maybe late night).
Here is the most recent article about the . The author is a board member of the Riders' Alliance:

I think there are 3 key points here:
An out of system transfer to the and to Atlantic-Barclays could increase ridership if these folks know they had an easier way to connect to these lines. It's something that the could explore.
A crowded train is defined as every seat taken and a quarter of the train standing. Well, some people put their packages on seats and since the uses a fleet with two-seaters, does that mean the considers a seat with a package as taken? If so, that's illogical and they need to seriously overhaul this definition of a crowded train.
The reason for low ridership is because, as the article says, they avoid the because it doesn't run very often(which is true), waits are too long(definitely true. I know this firsthand) and that the is always crowded(only point in the article that is not true). They can run more trains and cut wait times.
Simply put, I don't see the hesitation in at least experimenting with enhanced service. As I mentioned, run it in place of the when the isn't running and maybe follow the points I and the article points out and the low ridership that is pointed out in above comments may or may not change, but if we on't try this, we'll never know. It can't hurt any line and any commuter. A moving walkway at Court Square is not the answer(threw that in as a random thought).
