Hi and greetings from Denmark.
I can recall a scene of a big train that doesn't stop but smashes into a trainstaion (is in slow-motion) and is at the end of the film. I believe to remember a (red?) spotscar is on display in the station and is gently pushed off it's display and gently rolls to a stop in front of the "heros" in the movie who then drive off in it.
Hope this rings a bell for sombody, and any and all help is much appreciated.

I do believe you are speaking of "The Silver Streak", staring Gene Wilder, Richard Pryor and Jill Claighborne.

Hi Donf
You are right on the button.
Thank you so much, now I can sleep again!
Best regards
Bent
