6A was built in 1901 by the Victorian Railways at Newport Workshops. It is one of Puffing Billy's NA classs of locomotives. In a recent overhaul (in the Puffing Billy Railway workshops) 6A was given a modern design exhaust system (in the smoke box) that makes it more powerful that other NAs. This new design also makes the locomotive use steam more efficiently and thus 6A has a softer exhaust than the other NAs.
