Trackbolt,
The Lehigh Line from Allentown to Lehighton boasts up to around 10 trains. The NS 40/41T run over it usually in the early morning on week days and usually 5 PM on Saturdays. The NS H66 runs to Lehighton to pick up interchange cars from the R&N PILE and to sometimes interchange cars with the H78. The H78 runs from Allentown to Hazelton. The train recrews in Hazelton while they are there. Canadian Pacific 166/167 and 410/411 operate on the Lehigh Line also. I am not sure of the exact times of these trains but they do run daily as far as I know. I am not sure if any trains run south of the Walnutport Area to serve any industries that maybe down that way. Also, don't hold me responsible for wrong times on the trains...I usually only foam there on the weekends.
:D
Here are a few links to pictures of the trains I spotted around the area.
NS H78 at Packerton.
This picture is at Packerton with the old CNJ or LV building in the background.
NS H78 at Lehighton.
This picture is of the H78 at CP-Lehighton. The Ex-CR SD50's are being taken to a leasing company after being held at Pittston/Riverside Yard on the Reading and Northern Railroad for the past 2 years.
Take Care.
