9v Lego Train (Old Set)

Is there a year of release for this set Nigels? I like the character pushing the hand cart with the barrel on it.

This set is from 1991 and is called the "Load and Haul Railroad". Brickipedia and the Bricklink catalog seem to suggest that this was the first 9V train set released, with the introduction of 9V trains the same year. Hope this helps.
