I started by making a scrolling, tiling train.Then I used displacement maps (in a similar way to the shear filter) to make it slanty. Two copies of this with opposite slants on them can be combined into one animation to make a kind of braid of trains. Then the polar coorindates filter turns it from a tiling animation to a circular loop.
