Yep, that did it. That is weird.

I need to add, it seams to work once, then doesn't load again event though there is plenty of fluid.

It is not working

I have pumps on both sides of the rail pointing to the rail. it is lined up at the center of the tank. There is plenty of liquid, it just don't load the train. What am I doing wrong. I have 1.3.1 and factorio 0.12.35
