Chapmans Line (Lehigh)

I had a question reference the Chapmans Line which is operated by N/S, Where does the line end going to the North. I followed it by car up past ALPO or now called Friskies yard but it goes between private homes and not by any road.

Does anybody know where this line ends at?

They also added more track in the Breinigsville area for Nestle Distribution, DSC Logistics and a few other new warehouses one being DHL. The lower part of the line can be followed but get lost North.

THANKS
Steve
