I figured on prioritizing things that would cut the run time (including add capacity). Gateway's a bit more important due to Sandy and volume, and will expand capacity in the long term. B&P Replacement will speed the line from 30 MPH to 79 MPH and expand capacity. BWI's essentially a 2-track station when it needs to be a 4-track, 3 platform station -- you can speed up even the Accela with a rebuild.
But then I'd also 4-track as much as possible through the line.
