Well, it's been a while since I've seen the episode, but "Sidetracked" takes place mostly on a train, so there may be railroad crossings in it somewhere. I'm sorry that I can't be any more exact than that right now.

This blog does remind me of one of my favorite Disney shorts growing up. It's called Toy Tinkers and it has some toy railroad crossings in it. It's the first thing that came to my mind upon thinking about railroads in animation. It's been forever since I've seen it, and yet I remember the little train set pretty well.

Good luck on your search.
