Sparking Things Up: Acela Express power car #2009 experiences some arcing as it brings up the rear of Train 2170 on Track 2 at Princeton Junction during the golden hour on Thursday, February 15, 2018. With the ongoing New Jersey High-Speed Rail Improvement Project, constant-tension catenary is being installed on this stretch of the Northeast Corridor. Track 2 has not yet received that upgrade. Once it does, arcing like this will be less commonplace.
