I’m sure by now, Caleb Schilling is sick and tired of the azure saddle LEGO part he’s been working with throughout this round of Iron Builder. But, build by build, the LEGO Master continues to find new uses for the clunky piece. This adorable locomotive is no exception, utilizing 31 of the saddles. While they’re primarily used to make up the sides of the engine and attached cars, each one features a new configuration, showcasing each of the part’s sides. The pairing of the dark azure saddles with dark blue and black makes for an excellent color combo, and contrasts the blurry green background of the countryside whizzing by.
