We had discussed the catenary contact issue here and on Facebook. During the initial tests there was excessive arcing even at lower speeds through Princeton Jct, and some of us had commented that this would not be acceptable. Turns out apparently that is an issue that has been addressed and took time to fix. Interestingly all this is in a segment that very short few mile segment that actually got constant tension catenary.
Apparently there was more serious issue at the so called "upgraded catenary" that the rest of the NJ segment got. The fact remains that NEC is really still a line that is held together precariously with every mile a special case, and hence will continue to be more expensive to maintain and operate than a newly built line of similar length, and there is really no way to fix it beyond a point.
