When the weekend-only Super Off Peak Day Returns [CBA] were introduced
to where I live on what's now Great Northern they were only into London,
but now there's an outward flow as well.

Yes, they must have been introduced not so long ago. Annoying that they
didn't exist in the first place.

I suspect they were to encourage local yokels to go up to London for the
day, rather than give an unexpected discount to tourists visiting
Cambridge from London.
