Climax model A geared steam locomotive - designed to fit a Kato 11-106 powered chassis. Perfect for logging layouts.Nice simple set of prints (no scaffolding or raft). Break off the supports for the tank in the frame then glue together with super glue. There are a number of voids, the loco needs weight to run well, so fill up every nook and cranny with BBs. You can also grind down a washer or copper disk that will fit between the boiler and chassis.
