Plarail

Plarail (プラレール, Purarēru) is a toy train and plastic track system made by Tomy and introduced in Japan in 1959. It was expanded into a battery-operated electric toy train system in October 1961. Plarail is not compatible with most other brands of model railway, although as it has a similar rail gauge to the wooden toy train systems, rolling stock may run on both systems to some degree.
