Action accessory for use with travelling toy

An action accessory for use with a model train, or the like. The accessory includes a first figure toy in the shape of a toy horse, and a second figure toy such as a cowboy for riding the horse and for removal therefrom. A frame is provided having an inclined ramp portion for rollably supporting the horse for movement on a path of travel generally parallel with the tracks of the model train. The frame includes a dismounting cam device at the lower end of the inclined ramp portion, which engages the foot of the cowboy figure on the side of the horse opposite the train tracks thereby causing the cowboy to dismount or alight from the horse directly onto a moving train, particularly a certain car thereof. A selectively operable lock is provided on the frame to maintain the horse and rider at the top of the ramp and for releasing the horse, causing him to travel down the ramp, in a timed relationship so that the rider successfully boards the moving train.
