LEGO 40370 Steam Engine was a 188 piece promotional set with 1 minifig released in 2020. This set was a free promotion item in LEGO stores and LEGO.com online with qualified purchases. This is actually almost a brick for brick reissue of the LEGO Push-Along Steam Engine (7810) set that was released in 1980. There are slight updates to the build with newer parts but essentially the build concept is the same.
