I think my favorite part of this model so far is the fact that it uses the interchangeable cargo pods that vanilla trains use. It allows the player that extra layer of flavor in terms of ship appearance to further make it their own. It also makes sense for the purpose of quickly loading and off-loading entire cargo pods on any given station to get the ship itself moving while dock workers deal with offloading the pods even after the transport is gone.
Additionally, the giant pair of struts running along the top-mid portion of the ship are neat. They also let the player see the pods from the top-down perspective (I'd also imagine slam-dunking a SNAC-shot between those rails and watching a pod blow off being immensely satisfying, even though the ship itself wouldn't take damage). I'm looking forward to progress updates!
