The next building I designed in my Railroad Town was the Livery. My thought were: I had the Train, the train dropped passengers for at the Train Station I designed. If the passengers wanted to travel or set up a farm, they would need some place to rent or purchase horses and wagons. So the Livery was created. But, it needed a horse, a wagon, and the building.
Yes, I made the horse a lot bigger than it needed. This helped with the details when I scaled it down. The joints are their in case I want to pose the horse in future designs. Link to view the horse in 3d: https://www.tinkercad.com/things/jTh69Npb1Eu
The horses were imported into this design as STL files. This allowed the design to load faster. Link to the wagon in 3D: https://www.tinkercad.com/things/1aXkcSkeSV0
The water troughs and hay was taken from other designs. Yes, the wagon was designed for the canopy on the wagon to be removed. Link to the Liver in 3d: https://www.tinkercad.com/things/lGqOUWemGMK
