I can't believe that I didn't think of a pipeline first. So... yes.

Also another argument against trucks: they consume fuel to carry fuel.

I'd say there are orders of magnitude of difference between attacking a narrow passage of water that borders your very large country (here the narrower the area you want to block, the better), versus a few-meters-wide railway that starts in another country and goes thousands of kilometers in a direction pointing away from you (and in the second case, the narrower the target, the more difficult to hit).

Well see? Problem solved!
