Using a certain seed part as a focal point for a build can be challenging but in a good way. Constraints can fuel creativity… like in this clever little train by Thomas Gion that uses a particular Technic connector for the center of the steam engine. And while this is a great part usage, my eye was drawn to the genius use of sideways tiles inserted into the base to form the rails and slats for the train tracks. The simple stone arch and landscape round out this small but mighty model.
