Hi Ed, There's basically three reasons they use the twin motor design. First
is the toy train sound systems are huge compared to DCC so they need that space
in the center of the loco to fit all the crap in. Second is they are more
reliable in a toy train environment as they are mounted to a rigid truck with
no u-joints to worry about. and third is the toy train crowd hear the words
"two motors" and think they are getting more for their money, they don't know
that two crappy motors cost less than one nice motor.
The dis-advantages of the twin motor system is they usually use a high speed
gearing design to keep it cheap, as you said two motors are harder to
co-ordinate than one motor co-ordinating with it's self, The twin motor trucks
are rigid not equalized, and the front motor sits in the cab area....DaveBranum
