It's a train, which is on brand with the theme of how dairy helps brains, bones and bodies work together grow. It's an important message; thanks to bizarre fads and activist campaigns, kids probably don't get enough food-based calcium and Vitamin D. New York, like California and a dozen other states, instead prefer pills and supplements because they think 'food is medicine' - unless it is yogurt.
The conductor of the train is, unsurprisingly, a cow.
State Fair attendees won't get to eat it, though. After the event it will be recycled.
