Karate from Shaolin Temple - Kazuma Kenji (1976) - KCR Railtrack, Shatin

I can't give a specific location for these following screencaps but will say that the first one was obviously taken at the northern end of Shatin due to the proximity of the slopes of Ma On Shan on the right handside. Train enthusiasts may be more interested in the engine number here - 57. Marcus Wong of Checkerboardhill notes that this was one of 3 engines bought in 1961. Apparently it was damaged in 2009 and eventually scrapped in 2014. As you can see in the images below, this was before the system was double-tracked (circa 1979) and electrified (1983).

In the film, Wu and his sister are following the gang and their boss onboard the train, but at some point the pursuit turns into a car chase.

Bruce Lee fans may recognise Fung Ngai as the gang boss.
