Making big LEGO steam engines that run is hard work. LEGO train track has very sharp curves which mean all sorts of clever trickery is required to make a steam train even get around it without looking totally stupid. Fortunately Cale Leiphart is quite an expert in it and shows off a lovely 4-4-0 locomotive (that’s eight wheels) from the Maryland & Pennsylvania railway. The presentation in front of the Twin Cities LEGO Train Club’s layout is pretty snazzy too.
