Our museum is only aimed to continue the old museum, as the old museum is not even updated since 2009. Things change and history was rewritten by us a few months ago, and some crucial information in the old museum is wrong.
Was this the very first transition from the non-motorized wooden to the motorized set Vio?
電池で走る プラ汽車レールセット(1961年) Battery-powered plastic train rail set (1961)
電池で走る プラ汽車レールセット(1961年) is the first battery operated plastic train in the Plarail universe. We don't have the プラスチック汽車レールセット(1959年) A and B sets yet. So it was really プラスチック汽車レールセット(1959年) transition to 電池で走る プラ汽車レールセット(1961年).
There were others.
First generation ふくせんプラレールセット(1968年), not second generation.
First generation でんどうプラレールでんしゃセットNO.2(1968年), not second generation.
Single item えき, Merry-Go-Round tag.
Thanks Vio, that white just stood out to me for some reason.
