Looking at the NEC schedule, I just noticed that there are 3 trains which make New Brunswick/Edison/Metuchen/Metropark-express to Newark within a 12 minute span (3124, 3126, 3712) in the AM rush. How did this come to be? Do the second and third trains carry any passengers other than last minute commuters, or are they needed due to the first filling to capacity?
