Tie renewal on the Northeast Corridor, 2000s.

Color digital image showing tie renewal work near Elizabeth, N.J.; image dates to the late 2000s.

Tie renewal on the Northeast Corridor, 2000s.

In this image, crews use the track laying machine to replace ties along the Northeast Corridor (NEC) south of the Elizabeth, N.J. station; this section of the NEC is used by Amtrak and New Jersey Transit trains. To the right is a Northeast Regional train pulled by an HHP-8 electric locomotive.

Based on the design of the Acela Express power car, the HHP-8 can achieve a top speed of 135 mph. It has 8000 horsepower and features regenerative braking, meaning that energy generated during braking is returned to the power grid for greater efficiency. Fifteen HHP-8s entered service from 2000 to 2001 to supplement the AEM-7 fleet following the completion of the Northeast High-Speed Rail Improvement Project.
