This is a Lego model of a BNSF train engine. It is based on Lego set #10133. I built the train and train cars in LeoCAD, and then exported it from there into Blender 3.5. The landscape was made using a geometry nodes setup, and it instances in around 4 700 000 bricks. I made the Lego material myself (you can download it here). The textures are from AmbientCG, and the scene is lit by an HDRI from Poly Haven. Rendered at 4k with 2048 samples, and then composited in Blender.
Here is a top view of the scene, which gives you a good idea of why my computer almost blew up rendering this:
