First Steam Run! 16mm Roundhouse Billy | SM45 Live Steam Locomotive Test

All aboard for the very first steam-up of my recently acquired Roundhouse Engineering “Billy” — a beautiful 16mm scale (SM45 gauge) live steam locomotive! Watch as this British-built workhorse breathes steam and comes to life on the rails during its inaugural test run. Built by Roundhouse Engineering Co. Ltd., the Billy is a classic meths-fired (or gas-fired) live steam loco beloved by enthusiasts.
