You 'can' have the centre axle driven: you need to use an axle hung
motor and have side beams between the centre axle and one end axle,
and then have a centre pivot for the other end axle (like on an 0-4-
0). All axles need to have sliding hornblocks and guides. See
'Locomotive Kit Chassis Construction' by Iain Rice.
I've not tried this; the only 6 coupled chassis I've had a go at was
in OOn3, where there really isn't room for side beams on the driven
axle. In any case it's more complicated, and if I could I'd fit the
drive to one of the outer axles.
Best of luck with it, whatever you decide to do.
