I have a train running on a loop where each stop has no conditions so it never stops, aside from the fuel stops which have a simple inactivity condition. However, the fuel stops never get the skip signal removed from them and the train will run out of fuel, because the train never changes state, so the code to check whether fuel is needed and enable the fuel stops never gets triggered!
Is it silly to have a train that never stops? Yes, but gosh darn it I want my silly train for scenic purposes!
