Are They Serious?

[Super]

I am curious as too what it sounds like. Has a switch on the roof, wonder if it has a variety of sounds or just one which would become quite annoying after a while. There does seem to be some Japanese writing (I think) within the white stripe on the side. Wonder if this was part of a released train or sold individually. If it is from the 80's as the listing states, and it just makes a choo choo sound it must have been for a steam train and not a commuter or the early Shinkansens.
