NS Cement Region

Hi all,
Can anyone give me a bit of insight on the NS operation up to Nazareth, PA?
Thanks!

I used to live a few blocks from a grade crossing in Bethlehem along that branch. I believe service is daily, though I forget these days about what time the train made its way north. There are, I think, also a few lumber companies that get service along the branch as well as the various cement plants.
