The Belfast & Moosehead Lake Railroad is run primarily by volunteers and runs only on certain weekends. One of the promo fund raisers they have done is a "Train Robbery" in which a show is put on and passengers are asked to chip in funds to the "Robbery", but the money actually goes to support the railroad and museum. Check the website events page to see if the "Robbery" is on.
