The fast blow glass fuses look like the ticket. I will go with 8A ones. Thank to everybody for the other suggestions, but the prices on the fancy, made for trains breakers are truly out of sight cost wise. Fuses and fuse blocks (holders) will be less than $20.00… enough to do 4 loops worth.
And another thanks to Tom for letting me know about the other forums. I had never looked beyond the train forums.
