There are a total of 8 clips filmed mostly in 1966-1967. Some are dated, some have accompanying info (below) from Bruce Chapman, and I've done my best to label key reference points in each video. There is no audio that was recorded.

The first clips are the most exciting, as the footage is filmed from inside the cab of the engine, essentially providing an unbelievable opportunity to experience (at least to some degree) the feeling of driving down the CPR rail track along Scott Street inside a train in 1967.
