There are no weight limit signs anywhere else (don't ask me why, the 
council itself don't know).

I don't see exactly why if we consider the ends of the ways and that, as 
data consumer

    * a program can easily deduce a forward/backward if that's its best
      option
    * a human can just just hold the map north up instead of finding the
      nodes order

Only the circle needs special attention and only if it's 8 shaped is it 
a real problem.
I just checked that 
en.wikipedia.org/wiki/Circle_line_(London_Underground)

When I was a kid, I used it as a merry go round for a few pence.

But I won't fight for that ;-)
