There was a discussion recently about whistle signals on a train with a tender-first (Backward) engine. This doesn't help determine whistle signals but you might like seeing three different doubleheader trains with steam shot in the olden days!!! Music is copyrighted also, was used in our America By Rail-The West Coast Route. This is an unlisted video, so only using this link can you see it. Enjoy!
