Interesting that one is called 'Kendal Green Crash' rather than Kensal Green, and also appears to show D stock!
There is a Kendal Green station, but it's in Massachusetts and isn't a terminus. The crash seen in the video above happened at Richmond in west London.
I've been to Massachusetts three times, and strangely, just over 2 years ago we stayed in 'Historic Concord', which is the next stop along the line. So I have actually travelled through Kendal Green on the MTBA (Massachusetts Bay Transportation Authority.)
And the Kiburn crash is actually the Central Line crash at Leyton.
But it show A stock, so cannot be Leyton. Although the picture on the clip appears to be 59/62 stock, so may be a 'stock' (please excuse the unavoidable pun) picture.
The newsreel footage relates to the Kilburn crash (A stock and 1972 stock visible) but there is a brief mention towards the end of the clip to the then-recent crash at Leyton, and it is a still from that section of the report which is used in the caption. The Richmond overshoot in 1987 is wrongly captioned as "Kendal Green" (sic). There was a collision at Kensal Green the previous year, between a 1959 stock train and a class 313.
