As someone who actually worked on the original NECIP (about a half a lifetime ago), I find all this discussion by self-appointed experts amusing.
Two and a half hour nonstop timings NYP to WAS were achieved three decades ago with the original EMU Metroliners. If you want to go faster than that, and make stops, everybody knows where the bottlenecks are at this point:
1) NYP to Newark
2) The side-platform station at Metropark
3) Trackage from Zoo through 30th Street
4) The two-track segments between "Bacon" interlocking and "Bay" interlockings in Maryland
5) The Baltimore tunnels
6) BWI station and the three-track railroad between "Fulton Junction" and "Landover", which is congested with MARC local trains
Wilmington is a non-event. You're not going to skip it with many trains, if any. And the bottlenecks north and south of the station are being addressed by the state of Delaware right now (third track "Yard" to "Ragan"; proposed third track "Wine" to "Landlith"; proposed third track "Bell" to "Holly Oak").
Graham Claytor had the right idea, which Amtrak has pursued since the departure of George Warrington -- don't focus on more 150 MPH running; rather, speed up the slow spots. Over the last decade, Amtrak has installed a number of #32.7 turnouts at various interlockings. These raise crossover speeds from 45 MPH to 80 MPH, greatly increasing flexibility by reducing the time cost of moving from track to track.
A new route through Baltimore would save at least eight minutes of run time by itself. Do some work around Philly, and you could probably get another eight. Now we're down to 2:15 nonstop, and we can go from there.
