@Raven87 posted:Since I’m new to the legacy locomotive world, I’m not sure I understand why the kinematic coupler is used versus the type of couplers on the ones I have which have the coupler fixed to the truck? Is it because of the C-C truck type or another reason?
That spring pre-loading on the kinematic coupler looks (to me) like it could be an issue, especially with a lighter rolling stock unit behind it. Maybe I’m missing something?
You can search the forum if there’s a issue there would sure be a post.
As for why this a preferred pilot is simply prototypical. In O scale we must accommodate sharp curves in small spaces. In order to make the locomotives fit and so the coupler doesn’t bind, the coupler and pilot are fixed to the truck. In small switchers you’ll see fixed pilots because it’s a smaller locomotive they can actually fix the pilot and the coupler for the most prototypical look.
this kinematic pilot gives the fixed pilot look but when it needs to it can move so the coupler doesn’t bind.
