I just clicked the link posted by monica_pa and it looks the same as it always had for me. When I clicked on hints (bottom left) the possible moves were "highlighted" for me. (I don't use the hints so perhaps there is something different with that feature)

Here ya' go. Here is a link that might be useful: Train

It's not that hard. You just have to get the "hang" of it. One thing I learned is if the caboose is at the front of the line, start moving them. They go behind the passaneger train/ I try to start maneuvering the engine and getting it up front. You just have to learn what goes where. I lose, but then again I do win.

Oops! Sorry for the double post. I didn't realize the first one posted. I need to wake-up...lol!
