That's a 20 minute trip where I believe you'll manage to get to 135 MPH for a brief period.
Unless they have recently installed ACSES Phase I in that part of the railroad I don't believe you get upto 135mph there. AFAIK ACSES is currently installed only in NJ (in the NYP - WAS segment of the NEC), but that information is about 2 years old, so it may have been added elsewhere, since they are supposed to progressively add ACSES as an overlay at least to those portions where speeds in excess of 125mph would be permissible with appropriate signaling and civil speed enforcement, i.e. track is FRA Class 8 (as per 49 CFR 213.9 and 213.307).
One way you can get a hint on whether ACSES Phase I has most likely been installed or not is to be on the lookout for one, two or three bright yellow passive transponders placed in the middle of the track right under the block signals. As you travel down the NEC between New Brunswick and Trenton look for them on the middle two tracks and at a few places on the outer tracks, specially at interlockings where a train can enter or leave the middle two tracks. I would be interested to hear about any sightings anywhere other than between New Brunswick (County) and Trenton (Fair) in the NYP - WAS segment of the NEC.
Of course you will see these at many places between NHV and BOS too.
Also note that the transponders used for ACSES are much larger in size than the transponders that NJT uses for ASES designed by a different vendor but fully interoperable with ACSES.
