An Amtrak Keystone, led by ACS-64 No. 631, roars south (Amtrak west) through West Windsor, NJ, leaving an NJT train in its wake while passing a MOW vehicle on the siding. The Princeton Junction station is just ahead, though the train will not stop until it arrives at Trenton. Note the new catenary supports recently erected along side the old as well as the new constant tension supports on the westbound tracks offering a unique contrast to the original rigid eastbound supports soon to be replaced. This is part of the NJ High-Speed Rail Improvement Program - a $450 million dollar project to increase speeds (160 mph) and reliability between New Brunswick and Trenton, NJ.
