Hello Sebastian,
The best I've manage to work out on this is with my 4-8-4 Northern engine as
shown at:

In this case, I put the leading wheels forward of the steam cylinders. The
cylinders stay attached to the same bogie/truck that drive wheels are attached
to. Not entirely prototypical, but it performs well when running on all sorts of
track configurations.
Hope this helps. If you figure out something else, please do share.
Cheers,
Ben Fleskes
