moved your train there auomatic or was it driven by you/just new build there?

i´ve seen this in my save often when driving the oil train manually around and not parking 100% perfect, i think the pumps could be a bit more tolerant here......
(so maybe let the train go there by it self will solve ...

while playing with the fluid wagon I have found that the pump doesnt actully pump the fluid into the fluid wagon.
this is my first time using the fluid wagon so I might be the one to blame, but I checked in videos that shows what to do and I have the exact setup as they have and still doesn't work ...
