What is this 'Funny Rail Set' ?

[Super]

Thats funny, why do they call it a "Funny Rail Set"? Definitely a clone but the question is was it made by Tomy? The box is almost exactly a copy of the Tomica World Road and Rail System ones. Everything about the train, tracks and accessories screams Tomy. I am recalling someone mentioning here about these but I can't find the thread. Something to do with rights or where it was released. Curious to here about it. Is this yours or you just saw this picture?
