NH RR GE 302 and #306? vandalism wreck on the LIRR Bay Ridge Branch at Ocean Ave, Brooklyn overpass

This was a case of vandalism. Kids threw a switch and watched the New Haven freight run into the roll-up door.
I have this thus far: Thus far: GE EL-C Electrics - Class EF-4 301-310 built 10/1956 known as "bricks". A photo of NH RR EF-4 electric locomotives # 306 & # 302 lead a manifest freight train c. mid 1960's (these seemed to be paired, perhaps!?)

Found a photo of NH 302 Photo Date: 3/14/1965 and later went as PC 4602, Class E-33, in 1969
Thus: Was #302 repaired OR the accident happened after this date of 3/14/1965!? (The mystery thus far)
The accident between Oct 1963 and 1969… Anyone with further details?

Can anyone point me in the right direction to find the date of this wreck? Thank you.
