Articulation of model locomotives

[NW Modeling List]

For the Riv Y conversion, I used the drive from the locomotive, I just had to reverse it.  I have also done one with the motor in the center, which also works.

>I think one of the main reasons these folks make them articulate the way 

they do is to simplify the drive train.  With a REAL articulated, they'd 
have to drive the rear engine in the normal way and then run a drive shaft 
forward to the front engine (some ingenious fellows put the motor for the 
rear engine in the tender and the motor for the front engine in the normal 
position, just driving the front engine through flexible couplings).

They way these guys do it, they can use a double-ended motor mounted in the 
middle of the boiler and run the front and rear engines like they would a 
diesel.  Easier, cheaper, and WRONG.

I'm surprised nobody has mentioned the Bowser 4-6-6-4 and 4-8-8-4, which do 
it right.  They're big engines, though, and are capable of sweeping cars on 
outer curves off the track if you maintain normal track spacing.  But they 
will go through a #6 crossover, etc. . .
