Young child's domino-setting train (The Sixth Form College, Farnborough GU14)

The train is powered by 2 x AA batteries (not included!). It trundles along, laying a series of dominoes in its trail from the large hopper you insert on top. There is a bag of many more dominoes plus a blue cactus (??!!). The battery cover is screwed in place to ensure small fingers can't pry it open! The train can be steered by rotating the funnel. Tested and works.
