The Fukusen Plarail Station Set was released in 1969, initially with a white platform, a clear red roof, and a mechanism that moved the dolls on the platform when the train arrived. A number of mould changes were made, with the roof changing to solid red and the platform to green or yellow, and the doll-moving mechanism removed.
The set was in the product line-up until 1974, with the station as an individual item continuing until 1975.

On the other hand, the Plarail Museum exhibit of the individual item http://parlorfleur-pm.com/station.html tells us that:
"It was released at the same time as the double track system appeared. When the vehicle stops, the bell rings, and when the vehicle enters the opposite platform, it automatically departs. Accessories are included, and the Shinkansen platform display contains traffic lights, shops and office worker dolls. It seems that the earliest product had a gimmick in which the doll moved on the platform, but since it was only confirmed in the commercial, it may be a gimmick only for the prototype. There are three platform colours, white, green, and yellow, and white is the oldest. The roof of the white platform is clear red, and the one of the green / yellow platform is just red."
