Its not only transferring power to eight wheels you need a very wide range
of gear ratios.  Starting from a complete stop you need a very large speed
reduction from the engine to the wheels.  You can't just slip the clutch on
a 12000 ton vehicle (numbers from Tim Clevenger) that would be a big waste
of energy.

Try coming up with a mechanical scheme to transfer power from one engine, to
eight wheels mounted on two pivoting bogies.
