I think the issue here is the 3 axle truck itself.
To work on a switch you would need to float the center axle a little - I’ve
seen this done in LEGO trains before - so that it can make that really sharp
bend on the curved part of the switch track without derailing.
|
My breakdown
crane has 3 axle trucks using standard LEGO wheelsets, and traverses points
just fine, although it does have 4 weight bricks holding it down.
|
It’s also not hinged to another truck; it only has to rotate around its center
point. Being attached to the motor truck, the 3-axle trucks in the GG1 are
being pulled a little bit off center as the wheels go into the curve, and I
think that’s why the 3-axle truck can’t make it in this case.
I’ll play around with the trucks at some point - but the layout won’t require
traversing the curved side of any switches at the show so I’ll live with it
as-is for now.
