Money Train — Michael Stewart

Danny Spence plans to stay in Gila Creek for only one night, but then he gets mistaken for a snake named Zeke Tolan, and from then on it is just one damn thing after another. He falls foul of the evil Ma Cole, gets himself on the wrong side of the vicious Hernando Ortiz and his sadistic bodyguard Bracho - and somehow this is all wrapped up with a train full of money that's rolling south of the border, right into the middle of the Mexican revolution.
