I’m not sure how well it shows up in the pictures, but the middle driver
axle is a ‘blind’ driver - the flanges have been removed from those two
wheels. This way, I’m really just running a two-axle configuration, the
middle axle is more for “show” than anything else!
By taking off the flange, the middle wheel can slide on and off the track as
the train goes around corners.
I’ll take some more close-up pictures of the trains this weekend, we’ll have
our train layout set up for the first time in a couple of months. And I
found the power cord for my camcorder, so I can shoot some short videos of
the different trains in action.

fyi
Big Ben Bricks LLC is working on a mold to produce an unflanged wheels for
purchase. John has a few prototypes of the ‘blind’ driver.

Well, stop wasting your time on LUGNet and get on with it! ;-)
Seriously Ben, we can hardly wait.
I gather these prototypes have some of the back of the wheel missing too, so the
flanges of the outer wheels can tuck in behind. These means the drivers aren’t
so widely spaced that they bind on corners.
Of course, you can always follow Larry’s suggestion and put the blind ones on
the outside, but it may look a little odd on a 6 driver set like this.
I’ve always kept all the wheels on the track, so my 4-6-2 runs as a 4-4-4 set.
I’ve only ever been able to link two axles with rods though, not all three.
The problem with a full set of coupling and push rods is that you tend to fix
the cylinders and driver wheels to the body, which means that the very front of
the train swings out a long way on corners.
A bigger challenge is to fit the cylinders onto the wheelbase, so it’s then free
to move around under the body of the engine. Your body can then be pinned to
the wheelbase on the front and rear sets of wheels, so it swings out less. The
drawback to this is that most prototypes have the cylinders right up alongside
the front bogey.

P.S. Is there anyone who isn’t doing a Mallard? I’m really going to have
to think of something else...
P.P.S. Whaddya mean, “FINALY a steam engine with drive rods!”? ::Ahem::
