@EvilMonkeyBoy it appears to all be scenery from within the exhibit. From what I read they are asiatic lions and the exhibit was made with the inspiration of how people and them live and tolerate each other in the Gir Forest. I’ve never been there myself but ran across the pic a couple months back.
Although not quite the same your train would be a perfect setting to represent the tsovo lions that terrorized the railroads of Africa.
