How is the Longest Continuous Path measured, and can it branch or loop?

Question

Accepted Answer

It is one continuous trail of your own same-coloured trains with no train used twice. It may loop and revisit cities, and a figure-eight counts in full, but branches you cannot walk without doubling back add nothing. Count individual trains, not routes.
