What did you do?
Setup posted in the following images. I had setup a train refuelling system with solid fuel earlier. Since I now produce rocket fuel I thought of swapping the solid fuel of my trains with rocket fuel using the refuelling system. To do that I placed inserter with solid fuel filters at the station which took the old fuel out and the new rocket fuel replaced the old fuel. (Before I had the rocket fuel some solid fuel were still on the input belt going through the train. After all solid fuel went through the train I connected the rocket fuel).Interupt Current Train schedule Head locomotive fuel window Tail locomotive fuel window
What happened?
After replacing all solid fuel with rocket fuild the condition of "all locomotives are fully fuelled" was fullfilled and I guess in the next text unfullfilled leading to a flickering and the train not movingHere is a link to a video I recorded
