This is not exactly what you requested but I have the dispatcher's train sheet for the stretch between Sparrowbush (just west of Port Jervis) and Newburgh Jct. for Wednesday, July 23, 1958.
I would assume that the symbol freights listed would have come off the Delaware Division. This is a hard trainsheet to interpret because it included Maybrook and there are several freights that show up for just a few miles, maybe connections to and from Maybrook. Anyhow, here are the freights that I assume would have come from or gone to the Delaware Division:
#77. 35 loads, 45 empties.
#87. 33 loads, 58 empties.
#91. 56 loads, 63 empties.
#99. 88 loads, 1 empty.
One train just labeled "ORDY", I assume it means "ordinary", the Erie's expression for an extra. 4 loads, 67 empties.
One train labeled "XC". 91 loads, 75 empties.
One train labeled "RW" (I think). It appears to have terminated at Port Jervis. 2 loads, 7 empties.
The trainsheet lists two different numbers of cars, one at the top and one at the bottom. I listed the top. The bottom numbers were usually larger, some like RW were much larger (33 loads, 143 empties). Since the westbound trains proceeded up the sheet, I don't know which are starting and which are finishing numbers.
#A74. (advanced?) 93 loads.
#NE74. Went to Maybrook. 81 loads.
#98. 118 loads.
#NE98. Went to Maybrook. 73 loads.
#100. 101 loads.
One train labeled "Drop" (I think). 95 loads. This one started at Port Jervis and somewhere along the line it split into two trains. One with 35 cars went to Maybrook, the other with 60 cars went on towards Jersey City.
One train labeled "MF." (I assume it meant manifest ) Also started at Port Jervis. 38 loads.
You will notice that the eastbound trains had no empties. The prevailing direction of traffic was east -as were the other railroads.
It is worth noting that 1958 was a recession year which may have curtailed this list somewhat - I don't know. Anyhow, here it is. Hope it will be of some use to you. If you have any question, let me know. Ted Jackson
