I used to see these boxed cake candle trains all the time at car boot sales in the 1990's. I even bought a whole mint lot and sold them on my toy stall at toy fairs as they appealed both to the miniature train and the novelty toy collector.
I always found the neat combination of the box and the item really nice particularly as everything is in miniature.
A similar set turned up again on a blister card. It's interesting but it doesn't hold a candle to the boxed set!
You can even get the set nowadays but the box seems to have gone up in a puff of smoke..
Would small plastic novelties like these appeal to you readers?
