This is a Baureihe 57 / Prussian G10, a German steam locomotive built in the 1910s-’20s for heavy goods transport. Around 2,600 Prussian G10s were produced, with an extra one – pictured here – arriving courtesy of Pieter Post, who has recreated the steam train in beautiful detail. Powered by a hidden Power Functions L Motor and BuWizz bluetooth battery, Pieter’s Prussian G10 is depicted navigating a wonderfully constructed forest track, complete with a transformer building and the best pine trees we’ve ever seen. Top of the billing however, is the smoke – which looks as real as anything made from plastic bricks could possibly be. Click the link above to smoke your way through a German forest in the 1920s.
