This is an N Gauge electric train model.
The Deki 500 Type first appeared as the Deki 300 Type equipment car in 1973. At the time of its introduction it featured a blue body with white stripe, and sealed-beam front lighting. By 1980 a total of 7 cars had been introduced; due to a long production time, each individual car features differences in arrester and headlights, front window shape, and the location of the taillights. It currently still serves in towing freight trains.
