Railways aren’t all built alike, and that’s what allows Pieter Post to create this awesome bit of recursion in a LEGO diorama. The green engine is a narrow-gauge steam engine, allowing it to be transported on a standard-gauge flatcar. The engine and flatcar both are magnificent, with lots of details that are so cleanly sculpted they blend in, even down to the wood-slatted structure on the back of the flat—a structure whose purpose escapes me. I also love that Pieter hasn’t simply shown the pair on a straight piece of track, but instead took the time to sculpt a small diorama. The uneven edges add a great deal of visual interest and give the scene a feeling of being part of something much larger.
