Conductor Switching Quiz with Coins???

[Corkscrew67]

Some of you Old Heads will know what im talking about, I have been trying to find the work sheet where you have a loop with 3 or 4 cars/coins and you have to set them out in so many moves somehow and the Engine can only go under the bridge 1 or 2 times. I have been trying to find it for 3 or 4 years now and we can't find the one we had at the yard office and would love to get a new one. Thank you for any and all help. if i posted this in the wrong spot i am sorry and please let me know, Thanks again

I've never seen this quiz, but Model Railroader used to have switching problems sometimes.
