Another loop that springs to mind is the Cathcart circle. If you have
just missed a train and going round the long way gets you home faster
than waiting for the next train along the shorter route then what's the
problem?

I live about 1/3 of the way round[1] a circular bus route, and might
also find this effect kicks in, because the frequency is only every half
hour. Tickets allow travel either way, though.

[1] compared to where the shops are on the route.
