Thanks guys.
Pure serendipity!
Jon, yes, the Catawissa Railroad was eventually absorbed by the Philadelphia and Reading, (P&R RR), in 1876 or so, and the next station stop after Catawissa was Rupert, where a spur went eastward and dead-ended in Bloomsburg. It's station in Bloom was shared by the Bloomsburg and Sullivan (B&S RR)...

...and the tracks heading out to the right of the next pic...

... are the B&S tracks, which began there, and ended in Jamison City, where the loggers came out of the hills Friday night! So indeed the "Ladies" had to brave all those trestles!
Incidentally, in an amusing footnote to history, most of the hotels in Jamison City aspired to cater to a more upstanding clientele, but the hotel where the 'ladies' plied their trade was called, (honest to God), The Blue Front Hotel. I'll leave it to wiser gentlemen to decide if it was because it was painted blue, or whether 'blue' might have referred to the activities within as being indecent/obscene/risqué, or if it was referring to the color of the logger's jewels come a Friday night!
