This March 10, 1899 article talks about a freight train collision at Riverside Junction, NY, but doesn’t mention on which of the three railroads that pass through the junction it occurred.
The Oil City Derrick, speaking of the engineer and brakeman who were injured in the freight collision at Riverside junction on Wednesday morning, says: “The injured men were placed in charge of Dr. G. W. Magee, but the work of the surgeon at Olean had been so well performed that there was little further to be done. The hurts of Mr. Spring, while painful, are of a rather superficial nature, but it will be months before Mr. McKinney will be able to use his injured knee, with the possibility of the joint being permanently stiffened.”
