Changing of the guard. Patrons awaiting the Georgetown Loop's evening dinner train watch with interest as Steam Locomotive #111 heads for the fueling station, as it comes out of service, following a day of excursions. Diesel Locomotive #130 has already pinned onto the passenger cars and will be the power for the evening train. As for the 111, after filling up on fuel oil, she'll head for the engine house, where her fire will be shut down and she'll be greased and oiled in preparation for another full day tomorrow.
