Dave,
In all honesty it’s beyond that. He could make it a day with an overnight stay then back home.
Start at the furnace cause he’s coming north into Pennsyltucky.

Then walk or follow the the old beds into Lebanon. Honestly there is still a good bit there you just have to search it out along the old line.

Once in Lebanon check out the old Cornwall station along with the Reading station. Then head head to the Union Canal for a boat ride.
Mind you this is Lebanon County which borders Lancaster so a lot of rebels there with sheering, yarn, quilting etc.
Then you can head over to Dauphin county and grab a 5 star hotel in Hershey with a floor where you can see the NS Lurgan branch from your room along with everything else.
I’ll warn you that strange people can be seen walking around with cameras in Lebanon though.
