Toy trains are inaccurate representation of equipment usually cheaply made for children.
Finally the Pangborns are mostly conjectural models of early locomotives constructed of wood and canvas. Finally there is the scale model. Many of these highly detailed models can be seen on the HO layout or in the model cases on the second floor of the Annex Building. Consisting of 1633 hand made parts, this model is on display in the Fair of the Iron Horse exhibit in the Roundhouse. The layout was built in response to visitors who were disappointed that the museum's famous travelling layouts were often being exhibited elsewhere.
