This 1938 map shows the crossing of of Hammond Creek in Trowbridge, and the crossing of Alder Run just east of it. I presume that is where the trestles were.

You might have to "click" on the map to get high resolution.
Also, Google turned up an interesting website - probably you know about it?

Reading the site brings up a question - it states the first RR to BLossburg was the Corning and BLossburg (1840), leased by the Erie in 1855. THen in 1876 tracks were laid from Elmira to connect with this line in Tioga Junction, and all of this was leased by the Erie as the Tioga Division. The 1927 timetable shows the train from Elmira only going north from Tioga Junction only going a few miles to Lawrenceville.
My question is, what happened to the rest of the line north of Lawrenceville, to Corning (the original Corning and BLossburg)? The NYC Fall Brook line (through Corning south to Jersey Shore, PA) also ran along this stretch before heading west at further south at Tioga. Did they have parallel lines for a while from Lawrenceville to COrning? From the website I mentioned, it seems this section of the Erie was gone before 1942 . ANybody know? Did the NYC/Fall Brook take over this section of the Corning and BLossburg, and there were never parallel lines?
