It was never fixed but much minimized when TS2016 was installed on a SSD. it was worse going north from Philly than it was coming south to Philly.One fault with the NEC is that in a certain place on the route ( cannot remember the location) your computer would freeze for about 30 seconds and then you could continue. Other people had this fault. Don't think it was ever fixed.
It was situated at a huge bend in the line which has a 50mph speed limit and (I think that) it was called Shores Corner or similar.
As I wrote previously:
I liked the route and thankfully its still installed on my PC.The worst one I see (tile boundary stutter) is in the NEC about 12 - 15 minutes out of Philadelphia (going North) at a 50 mph speed limit on the approach to Shores Corner.
