Dish carrying system
 Rails are laid out between a kitchen or food preparation area and a dining room in a restaurant and a number of tables are arranged along and on opposite sides of the rails. At least one vehicle for carrying food and pulled by a model locomotive runs on the rails to convey food prepared in the kitchen or food preparation area to a specific one or ones of the tables. Travel of the dish carrier on the rails is controlled by a control device installed in the kitchen or food preparation area. The food carrying vehicle has doors which are operable from both sides thereof to permit access from both sides of the rails, and the doors are preferably interlocked with a slidable tray in the vehicle to cause the tray to automatically slide at least partially out of the vehicle upon opening of a door.
