Without the roadworks could be due to the amount of layover time at each end been too small so a specific journey wont be able to make that much time up at the other end because it will have to go out on another journey pretty much straight away (ie 2 mins layover or something, again, im no expert).
They get three minutes at each end. However, there is about five minutes at Washington and three minutes at Concord to load etc.
Still unnacceptable for it to be not turning up, 15 mins late late etc. on regulary occasions.
