“As a gift with purchase, LEGO 40370 Push-Along Steam Engine is a cute, nostalgic model that will likely be popular with train enthusiasts and those who like vintage LEGO sets. It does move and can technically be played with; however, it's presented as a shelf item more than... More a toy. The build is simple enough that it can be put together quickly, and the addition of the base with its slick black and silver nameplate and 40 years logo make it an attractive display piece.”

“40370 Steam Engine, then, is a very faithful reproduction of the original loco, but with a redesigned chassis and a few changes to avoid stickers across multiple parts. It's interesting to reflect that the original instruction manual had 13 steps. This one has 46. I know the... More chassis is more complicated, and there's a base, but even so... If you have feelings of nostalgia for the 12v era you will want to add this to your collection.”
