A péniche (or spits in Dutch) is a steel motorized inland waterway barge of up to 350 tonnes' capacity. Péniche barges were built to fit the post-1880s French waterways and the locks of Freycinet gauge. They are 38.50 m (126 ft) long and 5.05 m (16.6 ft) wide. The specification is still applied for commercial navigation as Class I in the Classification of European Inland Waterways. By 2001, 5,800 km (3,604 mi) of navigable waterways in France corresponded to the Freycinet gauge, accounting for 23% of waterborne traffic. (from Wikipedia). While not an American prototype, these can seen on some smaller waterways in cities here in the US. In N scale they are 9.45” long and 1.25” wide. The Z scale models are 72.727% of those dimensions, or 6.9” by 0.9” wide. Two cabin configuration are included.
