My Z scale Layout

Item in this photo I have designed that are 3D printed. the coil car, the cranes, and the old time passenger cars. Even the switch tower behind the orange crane in the background. I couldn't find these items in a store so I just did a 3D file and printed it. these are all done in Z scale. They have the coil cars out now but when this photo was taken there was no cars in Z scale. The Brownhoist crane which only the black boom is showing the wrecking ball and crane block are also 3D printed
