I know this thread is somewhat older so I hope you all don't mind my bringing it back into action again.
I have never seen this movie (nor had I ever even heard of it, that I recall) until I seen it mentioned here. However, I am considering giving it a watch but, as odd as this may sound, I am a little uncomfortable/hesitant in doing so.
I never really paid any attention to the great supporting roles played by the likes of CN FP9As #6503 and #6525!!
It definitely appears that they used at least two locomotives (#6503 and #6525) from the footage between the concerts. There's some great footage at the very end of a CN worker closing the doors on a roundhouse with what looks like the back of an F-Unit next to it (I couldn't read the number).
Is this to say that CN #6503 actually appears in the movie and that a CN worker (an actual CN worker, not an actor) does, too?
Sorry if my questions sound weird, but there is a [personal] reason I ask of them.
My reasoning;
Unfortunately, her co-star CN#6503 appears to have taken the lyrics to the Grateful Dead's "Casey Jones" a little too literally and wrecked in a head on collision with SD40 5151 and 5080 on 28 September 1974 while leading 6609 and 6600 near McMurphy BC (mile 34.5 of the Clearwater Subdivision)...I guess I shouldn't have made that joke about #6505!
Of the two engineers (CN#6503) killed in this particular wreck...one just happens to be my Father!
