Ten days after Allen died, some of Allen's friends gathered for an operating session and discussion on the preservation of the railroad in accordance with Allen's wishes. When they left, someone set a furnace in the train room to 65 °F. Allen never used the furnace and had covered it with tar paper. This caused a fire, which was quickly reported and extinguished fast enough to save the house, but it destroyed the final, still-unfinished incarnation of Allen's railroad. The damage was mainly contained to the layout room, and the house was rehabilitated and sold. A few model railroad items attributed to Allen survive and have been authenticated.
