I too have heard the rumor about putting "grandpa" on the the Tom and Huck stage. But in the meantime, you can sometimes find "grandpa" sitting on the bench in front of the train depot (or one of the conductors standing nearby); and he is happy to tell you the Christmas story if you ask him. I got to hear it myself this past Sunday. It was really special even without the lights and music.
Also, I heard that the investigation into the train accident has been completed, but they haven't released the results to the public yet. So, hopefully we will hear something soon.
