Precisely! Well, not too precise, really. Actually only about 1/6 as much gravity as
on earth, IIRC, hence reducing the engine's adhesion significantly. The WEIGHT
of the train would also be 1/6 as much as on earth, but the MASS of the train &
its cargo - and the energy needed to accelerate it (or decelerate it) would remain
the same, so without the rack & cog drive the engine would spin its wheels use-
lessly trying to get the train underway, or slide for miles trying to stop it.

Really, Mr. Forney?

Surely you jest!!   And if you're not jesting, please see last line below (before the p.s.) ...
