**Describe the suggestion
A method of defining a node (eg circle in blender on the model, facing a certain direction), where dynamic connections between rolling stock can be joined, with one side being defined as a female or male connector
maybe like the track system where you model a 1m section, but obviously smaller length, and that makes the link. They follow when moving laterally and vertically.
This could work for brake lines, coupler chains and MU cables
with support for widgets to disconnect the lines which they will return to a modeled start position, eg coiled up etc

Along with allowing cars to have certain equipment if coupled, eg trains brakes, MU.

Looks nicer.
allows for more immersiveness
