I got a great suggestion in the last video's comments to limit the number of trains by using "sushi trains." I love this idea. I'm defining a sushi train as one that carries a little bit of everything in each car. As of this recording that means no filtered train slots, but in a future episode (Probably the next one) I'll change that, to ensure we check off every box as we go around picking up supplies.
