:::: I have a few links that establish that the site of the crash in 1950 is near the Kew Gardens station. 
 ::::# A photo of a train involved in the incident. Notice the electrified third rail in the photo. The Richmond Hill station has no third rail. 
 ::::# The ICC Report of the accident. The report describes the location as follows. This accident occurred on that part of the railroad extending between Harold [Interlocking], 3.7 miles east of Pennsylvania Station, New York, and Jamaica, N. Y., a distance of 7.5 miles. In the vicinity of the point of accident this is a four-track line, over which trains moving with the current of traffic are operated by signal indications. The tracks are equipped with power rails for the electric propulsion of tramp. The main tracks from south to north are designated as No. 4 and No. 2, eastward, and No. 1 and No. 3, westward. The accident occurred on track No. 2 at a point 6.27 miles east of Harold and 1.23 miles west of Jamaica. From the west on track No. 2 there is a 1 degrees curve to the right 2,408 feet in length and then a tangent 4,665 feet to the point of accident and 1,868 feet eastward. The grade for east-bound trains is 0.3 percent ascending throughout a distance of more than 4,000 feet, then 0.4 percent descending 2,770 feet to the point of accident and a considerable distance eastward.  The Richmond Hill station is not on a line that connects with Harold interlocking. The lines which run east from Harold are the LIRR Main Line to Jamaica (which Kew Gardens station is located), the LIRR Port Washington line, and the Amtrak line to Hell Gate Bridge. Further, the Richmond Hill station consists of an island platform on a 2-track line. 
 ::::# A Diagram of the Accident Scene from the ICC Report. According to the diagram, the point of the accident is 1,960 ft. east of the Kew Gardens station. 
 ::::# I believe I have presented enough evidence to prove and establish the location as the Kew Gardens LIRR station, not Richmond Hill.
