Help with trains

[Darth_Stewie]

Hi, I've inserted a basic moving platform with the func_train entity attached. I've set two path_corners, linking to each other as their next stops and set the train's first stop, al as outlined in all the major Worldcraft tutorials. When I compile my map, however, the train begins at the first stop target, but doesn't move to the second stop target. What am I doing wrong?

Thanks in advance for the help!
