The Santa Fe used them on their diesels in the 1950s, 60s, and perhaps beyond. They are really, really weird looking; sorry I don't have aphoto at this time, but basically, they look like vertical flaps above the blisters on the roof

I once read they were invented in the 1800s & by a lady. They were or are used to stop fires from getting started along side of the railroads. The early ones were on the smokestack of the engines.
Thanks,
