Code Review

This pull request correctly fixes a bug in TrainHoppingAnimation where status listeners were not being notified of status changes. The change from notifyListeners() to notifyStatusListeners(status) is appropriate. The addition of a regression test is also great. However, I found a small issue in the new test case where the expectation for the animation status after calling reverse() is incorrect. I've provided a suggestion to fix the test.
