Suggested definition: "All tracks that cross a module end plate and the track(s) that provide through route(s) between end plates
that are used by trains having the highest priority are mainline tracks. 'Between end plates' shall include tracks that return trains to the end plate where the train entered a module."
This definition allows passing sidings to avoid being classified as mainline tracks.
