NS Sunbury Line Guide

Note: This guide is for the Sunbury Line outside of Scranton. Please see the Scranton Guide for railfanning the line in Scranton.

The Sunbury Line has a complex and interesting history. Currently, it is owned and operated by [[ Norfolk Southern ]]. The line is certainly not in its prime, having its second track removed. However, the line still sees regular traffic today and there’s always rumors of expansion!

The Sunbury sees a very diverse range of traffic, although it’s common to see intermodal, sand/rock/hoppers, fuel/tankers, lumber/centerbeams, and boxcars. Autoracks are sometimes seen on southbounds, but never on northbound trains. In the summer months it’s also more common to see MoW related trains.

Since the start of PSR across all of Norfolk Southern’s systems, most trains have lost their “regularity”, and so the “Usual Time” column has been temporarily removed.

  • A hi-rail usually inspects the track once a weekend.
  • MoW crews are very active in the summer.

Clarks Summit Hill

CP-669 to CP-665, commonly known as the Clarks Summit Hill, is a 4 mile climb into Clarks Summit. This segment of rail is extremely steep for trains. So steep in fact, the once-daily train 37T (pre-PSR) would sometimes stall on the hill, holding up the whole line for the rest of the day!
