Blue Plastic Tracks

Hello everyone!
Could anyone tell me the name of the set that this feature comes from, or post a picture of what the box art looks like please??
Thank you.!!

I don't know the answer, Muddy, but I'm courious - is the poor cow spinning around when the train passes?

There's extra stuff in the box shown above.

Here it is at Akeda's Museum, D-51 Ranch Set (1976):


The cow rotates when a train passes (why? I don't know, I've seen a few cows in fields next to railways in my time, but I've never seen one do that!).

Akeda says that the cow crossing may also have been listed separately, but he's never seen one. No doubt Vio will add any further information that's available.

OK, I understand now, it's a technique for making butter inside the cow.

I knew the cow is doomed when I saw the first picture, but this....

I did write about this in the 50th Phantom Gem: https://blueplastictracks.com/showthread.php?tid=4035
Case closed?

Thanks everyone!!
