106916:10508 is Barbed Wire Fence by me and can be found here at USLW
106916:10510 is Road White Stripe Spline and has just been uploaded to USLW today
106916:1132 is my reskin of a David Drake tree, GF-OR White Oak leaf-off 24m, which I did years ago and thought I had uploaded to the DLS. If it can't be found let me know and I will upload it to USLW
155115:500026 is Criterion Store by galdalf0444, not sure where I got it
175455:101132 is JR RR Ties by 22alpha, should be on the DLS but if not then at JR
175455:101153 is JR Radio Signal Tower by 22alpha, should be either at DLS or JR
106916:100032 is my reskin of a JR ballast to match my reskin of one of the JR "ST" tracks to reduce the pink color in the ballast. Before I uploaded the route I swapped out the track and ballast for the original unreskinned versions to make things easier, but I must have missed a patch that might have found its way off my "ground texture" layer. You might just try deleting it and see if you have a small bare patch somewhere.
I'll try to chase down the rest for you tommorrow.
