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?
