If there’s a more ‘Choo Choo!’y Lego creation than this, we haven’t found it. Wonderfully built by Owen Meschter, this is a Class Y14 steam locomotive, as used by LNER at the turn of the century who classified them as J15s, and which saw service on British railways right up until 1958. But that’s enough boring train facts. You now have permission to run around your house or place of work shouting ‘Choo Choo!’. If anyone stops you tell them TLCB sent you.
