The Rockaway Record and the Denville Herald were owned by the same man at that time...White or something similar...but now is when local news reportingis non existant rather than then; there is a whole world of differences between then and now in the media.
To the subject: look into the Morristown Record, the Newark Evening News as well as the Newark Star Ledger of the time.
Although the track existed for years up to Indian Lake Road I do remember my mother driving us (a car load of kids from the neighberhood) home from school on a rainy afternoon. As we approached the Indian Lake Rd crossing we were stopped and had to wait as a track crane lifted the rails out of the crossing. One of the girls cried that the were taking the train away. Before that, I was often told, that one of the older neighbor ladies was incensed that the railroad ran a train across that crossing just as school was being let out in the afternoon and often would go there to stop the train!
I did get to ride the line once or twice...remember in 1948 I became all of five years old..so most of my memories are quite dim! After the abandonment the Dover Drill would pull around the wye to turn before heading east to Morristown and Chatham and leave a car or two of coal at Young's Coal yard. Amazing today is that the roadbed and bridge abutments are still visible between the Catty Hole and The Pond from Indian Lake Rd.!
Oh, look for the book Denville Days by Gill. Do go to the Denville Library and check what they have.
God Luck.
