Royce Runaround: NS H76 has left its train on Track #1 (former Royce Running Track), proceeded east to Port Reading Junction, and is now running west on Track #2 (former main track) to Sully. At Sully, it will couple back up to its train and proceed west to Allentown, PA. Behind the mother leader is its married slug: NS 623 (RP-M4C). NS 4666 was rebuilt from GP59 #4629 in October, 2016. The slug unit was built on a newly constructed frame during the same month.
